RE: E Flite Eratix 3D 25e ARF Owners Club
IdeaBeing is right. The Eratix is a great slow flyer. Unless you reinforce the ailerons, you are looking for trouble with aileron flutters and wing damage at high speed.
It's the closest thing to a "3D trainer" that I know of. Great hovering, harrier and knife edge capabilities. Great flat spins also with some practice.
I never get bored with this plane.
