A-40cc gas migt get a 15 lb plane up to speed but it would take a while. I would say you are looking for something like the 3W-56cc twin. If it's in your price range. No one makes off the shelf power like 3W IMnotsoHO I have one and a ZDZ50, the 3W56 makes half again the power. I also have a SPE-40. I think they bought these engines off a used paint shaker salesman. Mine flew twice and shook a tailsurface off each flight on a giant UDO. By the way it's free to the first person to come get it.

Have RCIGN1 build you up a G62 lite. Best around!!!! Capt,n

There is some solid advice. More money than the 40's but WAY more power. You would have a very overpowered, fast 15lb aircraft there. You could prop it for speed or for vertical and have a ball. As a bonus, the Zenoah's like to rev and there is no better way to speed than a small, high pitch prop at high rpm's. And Ralph's work is superb and prices dirt cheap.
