My CB100's tail motor had start problems and would go wild at times in general (does anyone know of this?).
Anyway, I decided to rip the tail assembly off my old 4#3B and replace the CB100's with it. Apparently you can just take the tail brushless ESC and plug the motor right in the Rx. I haven't tested it a lot so I'll have to see how it holds but it appears to keep up, although it is a bit less authoritative than the brushless. All of my CB100 tail rotors are broken and lost, can anyone tell me if there's a size difference between them and the 4#3 ones?
