Hi All,

I have the Ucan Do 3D 60 Size with a Super Tiger .90. Not happy with the engine the way it runs. I would prefer to get an OS max. The question is Should I get the (.91 Surpass 4 stroke) (The 120AX -2 Stroke w/ rings) or ( the 2-Stroke OS Max .90). Not looking to race around the field because the plane will explode most likely. But I want the power to do some nice 3D rising Spins, Blenders waterfalls etc. New to the 3D but have been flying for a long time. Any suggestions would be much appreciated.

Thanks a Bunch Guys
