FWIW, I just ordered an RCG26 to replace the Zenoah G20 I'm struggling with (see other thread).  If it weighs about the same, and turns a 16x6 at 8500 or faster, I'll be happy.

My G20 will eventually get sorted out (ran awesome before I crashed it), but for the price it was easier just to buy this motor and have something that runs.  I can't imagine anything worse than a 1:1 flight to deadstick ratio that I'm experiencing with the G20.
