                                        Taylorcraft BC-12D pilot test report 
                                        
                                         
                                        
                                        
                                        You can almost guess how long an 
                                        individual has been aware of classics of 
                                        the late 1940's by the amount of awe in 
                                        his or her voice when seeing a pristine, 
                                        restored BC-12 Taylorcraft. The reason 
                                        for that is the image many carry in 
                                        their minds of a Taylorcraft is of it 
                                        sitting lop sided on the back tie down 
                                        line, one tire flat, a bird-nest 
                                        apartment in the cowling and mice 
                                        running up and down inside the rotting 
                                        fabric. Cubs and Champs never slid down 
                                        hill as quickly as did the Taylorcraft 
                                        breed. Even though every pilot on the 
                                        airport recognized that Taylorcrafts 
                                        were far faster than the rest of the 65 
                                        hp group (with the possible exception of 
                                        8A Luscombes), the airport hobo was most 
                                        likely to be a Taylorcraft. 
                                        There's no good 
                                        explanation for the Taylorcrafts past 
                                        image except that there were just so 
                                        many of them around, some were bound to 
                                        go down hill. Although never produced in 
                                        the same numbers as the Cub, as soon as 
                                        old C. G. Taylor introduced his side by 
                                        side Model A in 1937, the market forced 
                                        him to crank them out like cookies. It 
                                        wasn't unusual for the factory to be 
                                        doing 30 airplanes a month in 1938 
                                        before the depression had even wound 
                                        down. 
                                        The Model A's had the 
                                        less then overwhelming A-40 Continental, 
                                        but it performed so well, every one 
                                        loved them. Then came the first of the 
                                        overhead valve Continentals, the A-50 (Taylorcraft 
                                        Model BC) and then a shining knight came 
                                        riding over the horizon in the form of 
                                        the Continental A-65. The A-65, more any 
                                        other single technological event, made 
                                        the Taylorcraft and every other of its 
                                        peer group take a giant step forward. 
                                        What had been a good airplane became 
                                        astoundingly good. 
                                        C. G. Taylor had an 
                                        eye for building clean, low drag 
                                        airframes. He got his lift from lots of 
                                        wing and his speed from low drag. On the 
                                        same engine with which a Cub could 
                                        barely make 80 mph, the BC-12 series was 
                                        easily doing 95 mph and some would touch 
                                        100 mph. 
                                        Taylor built 
                                        thousands of airplanes before the war 
                                        shut him down to start making L-2's. 
                                        After the war, they cleaned up the 
                                        airplanes still further and introduced 
                                        the BC-12D. There are probably more of 
                                        this model existing than any other. By 
                                        the same token, more BC-12D's died on 
                                        back tie-down lines than any other given 
                                        type. Go figure! 
                                        Mechanical 
                                        Description 
                                        Considering that it was built to beat 
                                        the Cub and humiliate C. G. Taylor's 
                                        late business partner, William Piper, 
                                        there's very little Cub in a Taylorcraft 
                                        BC. In fact, he did everything he could 
                                        to do it different and do it better. 
                                        The side-by-side 
                                        seating was a major departure, as were 
                                        the novel, for the time, control wheels 
                                        sticking out of the panel. Boarding was 
                                        via an automotive type door on the right 
                                        side. Eventually, another door on the 
                                        other side was offered and became 
                                        standard in later postwar airplanes. 
                                        
                                          
                                        The wing's airfoil, 
                                        rather than being the flat bottom Clark 
                                        "Y" or USA 35 everyone else was using, 
                                        was a semi-symmetrical 23000 series 
                                        known for low drag and less gentle stall 
                                        characteristics. For a wing that long to 
                                        be that fast with such a small number of 
                                        ponies available, it had to have a 
                                        low-drag airfoil. 
                                        The pre-war airplanes 
                                        used 1025 steel tube or a combination of 
                                        1025 and 4130. Postwar airplanes are all 
                                        4130. All of them have to be inspected 
                                        carefully for rust, if nothing else 
                                        because they are so old and most sat out 
                                        for so long. 
                                        The wings use 
                                        pressed-aluminium ribs over wooden spars 
                                        which also need careful inspecting. 
                                        Besides age, a surprising number of the 
                                        aircraft have been ground looped at 
                                        least once and the incident may or may 
                                        not be in their log books. The wings 
                                        have a lot of overhang past the strut 
                                        attach points and they could easily have 
                                        spar cracks which don't show except 
                                        under careful inspection. 
                                        Most Taylorcrafts use 
                                        Shinn brakes which are mechanical shoe 
                                        types with the lining on the drums, not 
                                        the shoes. Considering that the airplane 
                                        really doesn't need brakes most of the 
                                        time, the brakes work just fine. Their 
                                        cams can wear, but the units are easier 
                                        to repair than most of the period. 
                                        The A-65 Continental 
                                        engine is the standard by which all 
                                        small reciprocating engines are 
                                        measured. It's reliable, user friendly 
                                        and easy to maintain. Parts are still 
                                        available and overhauls still relatively 
                                        inexpensive, when measured against more 
                                        modern engines. If the mag. coils are 
                                        good and the timing is remotely right, 
                                        the engines will catch on the first or 
                                        second blade every time. 
                                        
                                        
                                         
                                        
                                        
                                        Flight 
                                        Characteristics 
                                        We prevailed on Gary Towner, an FAA 
                                        airline maintenance inspector in 
                                        Phoenix, to let us use his freshly 
                                        restored BC-12D as the test vehicle to 
                                        remind us how a T-craft flies. Towner 
                                        says when he bought his Taylorcraft, it 
                                        was a flying airplane but in need of 
                                        complete restoration. In the course of 
                                        taking it apart he found the spars were 
                                        riddled with cracks. As he put it, 
                                        "...they were really scary looking." He 
                                        feels all owners of aircraft that old 
                                        should take note of his experience in 
                                        that area. 
                                        His airplane was, as 
                                        near as he can determine, originally a 
                                        BC-12D-1, which he says was the bottom 
                                        line, low-buck airplane that didn't even 
                                        have a left door. The second door was 
                                        added sometime in the 1970's by a 
                                        previous owner. 
                                        As with most 
                                        two-place, side by side airplanes of the 
                                        era, getting in is as much a project as 
                                        flying it. In the T-craft it is made 
                                        more difficult by a diagonal brace 
                                        running across the end of the seat. 
                                        Once loaded up, Gary 
                                        and I were, shall we say, "cozy." Our 
                                        shoulders were definitely touching part 
                                        of the time. We didn't measure the 
                                        cockpit, but it is probably several 
                                        inches narrower than a C-150/152. 
                                        Visibility over the nose, however, was 
                                        good without even stretching. This was 
                                        important because the headliner was 
                                        nearly touching my head and I would have 
                                        touched it if I had to stretch. Part of 
                                        the Taylorcraft's speed comes from 
                                        having low frontal area and this means a 
                                        low cabin. It is low enough, in fact, 
                                        that turning your head sideways puts 
                                        your eyes right in the middle of the 
                                        wing root. To see to the side requires 
                                        ducking down quite a bit. This is more 
                                        of an aggravation than a danger, but the 
                                        lack of visibility is something to be 
                                        remembered at all times. 
                                        
                                          
                                        The big control 
                                        wheels are fun and the brake pedals are 
                                        funny. They are two tiny, thumb sized 
                                        pedals located well back and right 
                                        between the rudder pedals. They are 
                                        nearly touching one another. 
                                        Fortunately, they are used very little 
                                        in normal flight. 
                                        Taxiing is straight 
                                        forward with the only complication being 
                                        having to look down to dial frequencies 
                                        into the handheld radio mounted between 
                                        us on the front seat edge. That location 
                                        keeps the cockpit looking absolutely 
                                        original. 
                                        I hadn't been in a 
                                        Taylorcraft in years and my primary 
                                        memory was one of the airplane flying as 
                                        if it was very light. Gary's airplane 
                                        re-enforced that memory. As soon as the 
                                        power was up, the airplane wanted to fly 
                                        and I barely had the tail up before it 
                                        floated off. The tail is so far behind 
                                        us, it has lots of authority so very 
                                        little rudder movement was needed to 
                                        keep it straight. We had barely a breath 
                                        of wind, maybe two or three knots, 
                                        across the runway. Most airplanes 
                                        wouldn't have even noticed that wind, 
                                        but the second we left the ground, the 
                                        Taylorcraft instantly reacted to the 
                                        wind by drifting. I found myself 
                                        crabbing into a wind the windsock barely 
                                        recognized as being there. 
                                        The airplane has a 
                                        definite thistle down feeling to it and 
                                        wind is a challenge to it. The best 
                                        pilot on any airport is the Taylorcraft 
                                        pilot who easily and routinely conquers 
                                        a gusty crosswind. With firm hands, the 
                                        airplane will handle more crosswind than 
                                        is prudent, but most folks study the 
                                        windsock carefully before pulling the 
                                        airplane out. With such a light wing 
                                        loading and those long wings, it's 
                                        second cousin to a parachute. 
                                        It was fairly cool 
                                        out, about 70°, and the airplane 
                                        responded by giving us a fairly solid 
                                        rate of climb in the 400-500 fpm range 
                                        at about 65-70 mph. Gary says he gets 
                                        about half that during the summer and 
                                        prefers to fly the airplane solo in 
                                        those situations. 
                                        The air was liquid 
                                        smooth so we didn't have much turbulence 
                                        to show the Taylorcraft's cork-like 
                                        ability to ride over even the softest 
                                        bump. We also didn't have any thermals 
                                        to help us to altitude. More than any of 
                                        its peers, the Taylorcraft is eager to 
                                        lock on to even the weakest thermal and 
                                        convert it into altitude. 
                                        As we levelled off, 
                                        the airspeed stabilized at 90-95 mph and 
                                        Gary says he can flight plan 95-100 mph 
                                        and be fairly close. He's generally 
                                        burning around 4.5 gallons per hour and, 
                                        considering his airplane has both wing 
                                        tank options as well as the fuselage 
                                        tank, the airplane will stay in the air 
                                        far longer than he can. The ability to 
                                        go long distances in a reasonable time 
                                        on pennies has always the Taylorcraft's 
                                        long suit. 
                                        Because Gary had gone 
                                        completely through the control system, 
                                        including installing ball bearing 
                                        pulleys, his controls were surprisingly 
                                        smooth. There was none of the common 
                                        feeling that a cable was sawing a pulley 
                                        in half. Also, when racking the ailerons 
                                        around, the airplane was quite willing 
                                        to respond. We're not talking Pitts 
                                        Special roll rates here, but even with 
                                        those long wings, it rolled faster than 
                                        most of its peers. 
                                        Adverse yaw is 
                                        significant, but not as much as a Champ 
                                        and about the same as a Cub. The amount 
                                        of rudder required to coordinate is 
                                        minimal, but definitely there. In 
                                        checking pitch stability, it damped out 
                                        completely in less than three cycles 
                                        when pulled ten mph off trim speed. 
                                        Doing stalls was, as 
                                        is usually the case with this period of 
                                        airplane, almost a waste of time because 
                                        they are so benign. In a normal, slow 
                                        approach to a stall, the wheel hit the 
                                        stop somewhere in the low 40 mph range 
                                        and the airplane just mushed. If 
                                        accelerated, either in a turn or 
                                        straight, it would break slightly and 
                                        then mush. During the process I was 
                                        careful to keep the ball centred because 
                                        the rudder is very effective at those 
                                        slow speeds. As I remember, if asked, 
                                        the airplane spins very nicely and 
                                        willingly, with a positive recovery. 
                                        There's no doubt 
                                        you're in a fairly small cabin, when 
                                        cruising. Even though you can see over 
                                        the nose quite well, your eyes are 
                                        closer to the thrust line than we're 
                                        used to so the visual down angle is 
                                        pretty flat. Also, the necessity to duck 
                                        to see sideways is always there. The 
                                        overall feeling is one of being in a 
                                        long, narrow cabin, when really it's the 
                                        vertical height that gives that 
                                        illusion. Skylights would probably open 
                                        up the cabin feeling considerably. 
                                        When we came back 
                                        into the pattern, I reminded myself that 
                                        this airplane would really glide, so I 
                                        spaced us out accordingly on base. Even 
                                        so, I was too high. Fortunately, the 
                                        airplane is a good slipping machine. Not 
                                        as good as a Cub, but still good. Gary 
                                        said he uses 70 mph, so I did too, which 
                                        seemed to work out fine. 
                                        As I came out of the 
                                        slip and into ground effect, the 
                                        Taylorcraft's reputation as a floater 
                                        was again re-enforced. We may have been 
                                        a little fast, but, as we floated along 
                                        while I felt for the ground, I was very 
                                        conscious of having to be very judicious 
                                        with what I did with the elevators. Just 
                                        the slightest amount of too much back 
                                        pressure and the airplane would try to 
                                        balloon. Since we were slowing to a 
                                        near-walk this was more of a game, than 
                                        anything else. The airplane clearly 
                                        telegraphed when it was about to settle 
                                        or balloon and I just had to adjust 
                                        accordingly. 
                                        
                                        
                                          
                                        
                                        
                                        After a few seconds of floating, it 
                                        would give up and settle on to the 
                                        ground. On one, I held it off just a 
                                        little too long and felt it unhook and 
                                        drop us the last several inches. That 
                                        surprised me, but shows it's not a good 
                                        idea to hang it on top of ground effect 
                                        for too long. 
                                        All of the landings 
                                        were three-pointers, some better than 
                                        others, and none were even remotely 
                                        challenging during roll-out. The 
                                        airplane didn't want to do anything 
                                        unusual and was at least as easy as a 
                                        Champ or Cub to control. The wind had 
                                        pretty much died down, so we had the 
                                        best of all possible situations going 
                                        for us. 
                                        The T-craft is 
                                        actually quite a good bargain, even in 
                                        this period of rapidly inflating classic 
                                        airplane prices. A quick perusal of 
                                        Trade-a-Plane showed that even the 
                                        restored airplanes seldom touched 
                                        $20,000 with many restored ones with 
                                        low-time engines at $15,000 and below. 
                                        Un-restored airplanes were in the 
                                        $10,000-$12,000 range. When buying an 
                                        un-restored airplane, however, inspect 
                                        it very carefully. At sometime in its 
                                        life, it was doing duty as shelter for 
                                        all types of mice and varmints. When 
                                        buying a newly recovered airplane, make 
                                        certain all the rust and rot problems 
                                        were attended to.  |
