RE: GWs A10 EDf55's
If you don't put a new esc in - don't run the lipo to LVC as it will be set to low and you will destroy your lipo. Just make sure to use a timer.
The problem with your battery is the 300's will not run on AA cells. This setup has flown very well on 8 cells - but they are GP 1000, or any other sub A cell.
