HELI engine for a plane?
 

Is there any advantage of using a HELI engine for a plane?
If a .90 size engine is mounted in a biplane for example, would it have better performance than the standard plane? If YES, is the price difference worth it?

Any one who has done it, please share your knowledge :cool:

I had a 61 os surpass and put a o.s 32 heli carb on it and the difference was incredible in all areas. the heli engines have superior {o.s} carbs and can work on several types of engines if adapted to fit properly.

Well - one of the fellows here has an old OS .32SX heli engine in a .25-sized pattern plane (can't remember the name of the kit offhand). He'd retired the engine from heli use - many many flights in a Concept 30.
Performance is sparkling - it's really too much power for such a small airframe, as sudden applications of power will torque it HARD.
