Hey Everyone! [8D]

I have a 31cc gas engine . . . and i was wondering if it would be able to handle a 1.20 sized aircraft . . . would it be underpowered??

Thanks for the help

That depends on a few things:

- the engine (sounds like a Ryobi 31cc conversion)
- the airplane
- your definition of "being able to handle", and "underpowered"

I used a Ryobi conversion on a Dynaflite Super Cub and a Chipmunk. They both flew just fine.

I would not recommend such an engine on something like a CAP, Extra, Ultimate, mainly because of low power to weight ratio.

Well your correct about the engine being a 31cc ryobi coversion . . . and i wanted to put it in a sport plane something about 1.20 size . . . i want to be able to do some 3D . . . would this engine work or no?

Probably not. High weight, low power, better suited to a Cub or other slow flying plane.

That engine weighs almost 5 pounds ready to fly.
