It will work I was running a Sidewinder with 4s and CCBEC on a Novak 17.5 (~2200 kv). There was quite a bit of cogging at startup due to the gearing but once rolling it was pretty smooth. Now running a MM Pro though.

The Sidewinder was not designed for running above 3S. Some percentage of Sidewinders will NOT work at all on 4S. The BEC has a maximum voltage of 16.0V, 4S is maximum around 16.8V. Some percentage of the BEC chips detect an "overvoltage" condition, and shut the BEC output off.

i was planning on using an external BEC. can 4s be done WITH an external BEC?
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
