SUKHOI SU 31 LARGE SCALE
The Sukhoi SU 31 is a very capable aerobatic aircraft with a 400bhp 9 cylinder radial engine and a top speed approaching 300mph.
The model is also excellent at aerobatics and whilst not an out and out 3D design it is pretty good at this also.
Outfitted with display smoke, sprung u/carriage and wheel brakes it’s exciting to fly.
Rates on ch5 with up for normal, brakes on up elev’ and smoke on ch7.
Thanks to heelycopter and twoeleven for the excellent...
