RE: Big Stik 40
If the control throws were reduced to about 50% of the recommended ‘low rates’ values it might be OK. I have a Big Stik 60. Even with a good bit of exponential dialed in, the plane is extremely touchy compared to an actual trainer type plane.
Like a Cub or Cessna, don’t let the fact that the wing is on top of the fuselage fool you into thinking it is anything like a trainer.
