Thanks RCPilet!

I'll take a look at .90 size four strokes.

The story of your Bingo's demise makes me cringe ... even without the 100 spectators! [&:]

You're at 6,000 feet. Do you think being at about 700' I might do well enough with, say, a SAITO 82? Being on the lighter 72 case it's reputed to have a lot of "pop" for an 80 size four stroke.

I'd love the power I could get while saving some weight. What do you think?

BTW, hope your back is better. IIRC from your 4* thread, you were hurting considerably.

Thanks agin!
