which is a better 3D model?
Sounds more like you need a Morris Hobbies Sledge 540...
It will do 3D better than ANY .40 size airplane that I know of. Rock solid harriers upright and inverted. High alpha Knife Edge, great rolling harriers, high alpha circles are all great. Almost hovers hands off. It is completely nuetral, mine actually climbs just a tad when I roll inverted. It will do great KE spins and great flat spins...Elevators are easy, and especially fast with flaperons.
After the Sledge, I'd for the Seduction Wildstyle. I owned a Freestyle for about 6 months and LOVED it. Best kit I've ever had along with the best flying airplane I've ever flown! Just more pattern than 3D. The Wildstyle should be great...
