Here is the configuration that he suggests:
Jim lets get this configuration up on your website as the Electric Stock
class configuration. "3 cells Lipo for stock and 4 cells and up for open".
This is the config I used at the meet on Sunday.
Motor: 1110KV Scorpion SII-3020-1110
Battery: 3 Cell 3300mAh 40C TURNIGY 3300
Motor Controller 60A TURNIGY or Castle Creation
If we just limit the battery to 3 cells it will be easier to monitor and it
won't be as limiting to the new people interested in going electric to
selecting or finding what they think is a better solution.
And he was running a 10x10 prop with that and claimed it tested out at 85% efficiency (quoting from memory)
