Thanks, I drilled it for a Fox .35. That may be more than I can handle, the Ringmaster (and a Goldberg Cosmic Wind) with an Enya .19, and that had plenty of power.
I have been flying a ARF Bi-Slob, so I am not completely rusty, but I a little worried about the Ringmaster. Also, I never really flew any stunts, just circles and an occasional loop.
Anyway, I am glad to get back into it.
