RE: GWs A10 EDf55's
The battery you have will NOT work! It is way to big and heavy. They are sub-c cells and you need 2/3 A or AA depending on what motors you have.
A brushless motor is way more efficiant so you get more power and longer run-time. There is also no maintenance to do and no brushes to spark causing interferance.
We could help more if you told us exactly what motors , fans, esc etc that you have.
