Lets just say that this plane is no "Slow Stick". I have tried stalling the Funtana but it just starts loosing altitude. Give it more throttle and it flies away. The Funtana does not bleed off speed fast, so a longer appoach will be needed.
As far as the four stroke question goes there are guys using up to .40 four strokes I guess and if that is your thing, go for it. I like flying planes that have a good combination of power and maneuverablity. A Hemi powered brick is not what I'm looking for. If I stop and think about it a Hemi powered anything probably isn't in my future.
