RE: Larger Revolver
I'm glad they made a larger Revolver but i agree that the suggested engines are not enough.
In a nutshell, the new Revolver has a 4" larger wing span than the Venus II and is about the same weight.
After flying the Venus II with a 1.20AX i wouldn't want anything less for the Revolver. An os 1.20AX with a 14x12 would really move.
I would suggest the .95AX - 1.20AX in a 2-stroke and the OS 1.10a for an easy sport 4-stroke or YS 1.10-1.15 for some fun.
