Bec

[Brushless01]

Im going to run a sv27 motor and esc in a Delta force 29 knock off. I will be running 4s lipo :) But will i need a Bec or not ????

If running just on 4s for a total of 14.8v the stock esc bec will work, but if you disconnect the esc bec (pull back red wire for plug) and run a rx pack the esc temps should go down and run cooler since it's not working as hard. Either way will work. You gonna run the new sv27r motor or the older sv27 blue motor.

The older supervee motor found it in a draw and thought id use it. is the shaft meant to have play in it ??

side to side or in and out? A little in/out is normal

In and out i have 2 motors a used and new used doesnt but new does ??

That's weird, I think my old had just a little and worked great, i know my feigao has in/out movement
