Has anyone built this plane and used the .70 surpass engine, and if so How did it do in hover and about high would it get before it ran out of steam.

I'm right now trying a .65 LA on mine and I dont think I like the 2 stroke in this plane, people at the field say's it hard to get a 2stroke to hover and tork roll...

and aslo would anyone consider the .90 to .91 4 stroke a good engine size for this plane ???

thank you
