So, I'm out of the running this year for stunt due to a sore shoulder.  I'm learning to fly left-handed.  I figured out today that while I can't fly stunt, I can probably manage carrier.

I don't have any suitable engines on my shelf for either Northwest 40 or Northwest 15, but I do have a Flying Clown and a Ringmaster that would work (with some work).

Is there a good off the shelf 15 that can be used for casual carrier flying?  I have no chance of winning; I'm more interested in something that'll be easy to start & adjust so I can go out and have fun.

ASP .15 or Magnum XLS .15 same engines!

It looks like 40FP's are more common on eBay; I'm thinking of jamming that on a Ringmaster for NW 40.
