Has anyone tried this motor?
You have to scroll down and the motor is listed as an optional motor for the Freewing F-16. It is shown to be a CP480-3300-40EDF 3300kv Upgrade Motor. It is an outrunner, but does NOT have the standoff like this CP motor.
The first one I'm sure has the 4mm shaft while the second one is the 3.17mm shaft. The problem though is the first motor isn't listed seperately on the RC Castle website.
