RE: 15cc Gas RCGF engine information thread
Siday,
Go with the RCFG 20cc. I have two. One in a Hanger 9 Hellcat and another in a BH P-36. They both work great. Plenty of power but not "over powered". I think that the 15cc would be a little underpowered and not much difference in weight or deminsions between the 15 and 20.
