Is this loud sound flutter?
Had a friend put my Lazy Tiger P51 in a start of a dive and heard this pop -pop -pop noise. Is this a control surface or is the wing sretching the rubber bands out and bouncing. this was a very loud noise.. I'm running a 32sx, which has pretty decent power. any Ideas how to correct? or what the heck is going on, I dont think a small surface could make that loud noise? Could it?
