Express are you going to run it on 6S or 12S Just ordered mine and haven't decided on what motor to go with yet.
You are right about 6s being just fine. There are some benefits to be gained by going with higher voltage though. It would cut the amps in half which gains efficiency by less heat loss etc. We have one or two threads here on the site discussing the benefits of 12s on a 30cc airframes.I don't really see the need or reason to go to 12S. 12S is a 50CC type of power system, that'll fly any 50cc airplane with power and authority. This is a 35cc airplane, and 6-8s would be ideal. It flies awesome on 6S.
