The Sonerai I is a mid-wing
sport plane, racer, designed to meet all Professional Race Pilots
Association (PRPA) and Formula Vee Racing requirements for 1600cc
Volkswagen powered aircraft. The Sonerai I will accept engine
displacements from 1600cc through 2180cc.
The Sonerai I uses a minimum of different sizes of tubing to reduce the
cost, without hampering the integrity of the design. The wing is all
aluminium and is composed of two panels that fold along side the fuselage,
enabling the Sonerai I to be towed tail first on it's own gear.
Stainless steel cherry rivets are used to skin the wing. The fuselage and
tail surfaces are constructed of standard sizes of 4130 steel tubing that
are fabric covered. All aluminium sheet used is 2024-T3 .025" except for
the spars which are .040". The fibreglass cowling removes easily to allow
complete access to the engine, magneto, tank and instruments. The landing
gear is manufactured from 1/2" x 5" 2024T-351 aluminium. The Sonerai I
features an 11 gallon tank.
