Help,
I used the engine intended for my 40 size Kyosho Cap 232, (Saito .72) in my World Models P-51. Now I'm ready to start work on the Cap, I don't know which engine would work best. I have an OS 46 FX, an ASP .46, and a Thunder Tiger GP .61 . Any suggestions from someone with one of these? Is the .46 enough? Is the .61 too heavy?

Thanks,
Randy
