The STORM RG revolutionizes the flying
experience, offering pilots more performance, more freedom,
increased satisfaction, and a better value than any other fixed gear
aircraft in its category.
Now, 10 years after the STORM revolution began, the history of
unparalleled innovation, and the heritage of best-setting
performance continues with the STORM RG. The STORM RG represents the
culmination of more than a decade of research, testing and
invaluable input from STORM builders and fliers. Redesigned from the
tail forward, it’s fast and easy to build.
The fin had to perform up to the tremendous top speeds that pilots
expect from STORM aircraft. However, a higher emphasis was placed on
low speed handling. To keep area to a minimum, the fin has a unique
double taper to maximize the lift distribution from root to tip.
This also allowed us to eliminate all "washout" which can compromise
efficiency. This new airfoil creates extensive laminar flow across
more than 50% of the surface. The low-drag laminar "bucket" is also
wider than before, further increasing overall performance. The
result is very carefully "tuned" fin design, which enhances overall
S.G.Aviation is very pleased that the new STORM RG fin exceeds all
expectations, with lower stall speed; better roll rate, improved low
speed handling and higher top speeds. Ultra-high-speed cruise,
comfortable control stick forces are the result of an intense design
At the other end of the performance spectrum, the STORM RG’s
low-speed roll control is nothing short of remarkable, and the stall
behaviour is "straight ahead." The addition of simplified Fowler
flaps further increases the wing’s maximum lift coefficient to
enhance this low speed handling. This translates into the safety of
slower approaches and shorter landing distances.
The main landing gear is made by two supporting beams hinged around
the end of two metal leaf springs house inside the fuselage. This
arrangement still allows, in a retractable gear, the use of the
spring leaf for the landing shock absorption, preserving therefore
all this advantage (simplicity, reliability, maintainability). The
main legs are simply rotate by two pneumatic actuators.
The front wheel is integrated with a high efficient oleo-pneumatic
shock absorber. The steering and the braking system are unchanged.
When the landing gear is down the torque-arms are mechanically
blocked, preventing the rotation unless driven by the actuators. An
electrical compressor gives the necessary pressure to the pneumatic
system headed up by two spherical tanks. One tanks gives the
necessary compressed air in case of system failure. In any case the
gravity assures the landing gear extension. The panel indicators
(up-and-locked, down-and-locked) comply with FAR requirements.
