RE: Zenoah G20 prop and rpm numbers?
Z,
I'm at work until 7 this evening. I will be able to measure the motor then and post result.
You might call one of the CRRC 26cc distributors and see if they have it. One is PRCmodel.com (Canada), another is valleyviewrc.com, and one more RCOnlySite.com
Hope you can get info from one of these, I know you are ready to buy an engine.
I will check this thread before I go home and if you have the info I will not measure mine (it's inside the cowl, I should be able to get a reasonably accurate measurement).
Bill
