I've decided to build a 110 from the ground up as a little project. I've got mostly everything figured out I just don't know which motor to buy. I've been looking at a few sites and can't figure out whether the motor is for a 110 or a 50. The motors that I'm interested in are the GPX/YX ones. From the looks of it though, their 150/160cc motors have mounts a 50 frame instead of a 110. Any tips?
