L size without overheating

[lincpimp]

Well, I have had experience with most of the l can motors, and the best combo I have found in an emaxx is a 15l on 5s thru a bk9920. I can get slightly more than 30mins on a 4400 5s lipo. The bk esc does fine and does not really get warm. I have a clip on heatsink on the motor and it says under 150 for the entire time. I do have an RCM heatsink/clamp that I will put on the motor. I am not sure that you will have as much success with 4wd, but it is your best bet with a l can motor. The xl series will stay cooler, but I just purchased a hacker 15l, and I feel that the better quality will help with temps and effeceintcy, which is the main issue with feigao motors.

A 9l on 4s will run hot. A 10l will be better but not much. An 11l will be the best bet on 4s, but I am not sure the temps will be what you are looking for. A hacker eqivalent may possibly do what you want.
