RE: Raising stall speed?
Now the spoiler idea is a good one. I will try that. I think maybe just some 3/8" tri stock. I want to add, this Nextsar aircraft, I do not like. I do not like the wing droops and flap dealios they added as a marketing ploy. The only good thing about this trainer is the engine. It is basically a .46 AX. Once you get the stupid needle restrictor off it runs great.
It would be nice to just have a simple, practical, tried and true design without auto pilot, simulators, wing droop, spoiler flaps, lean needle restrictor, poor inefficient props included with these trainer packages. Just lower the price! As an instructor, these are just obstacles that have to be overcome every time I greet a new pilot.
