means capacity, so u calculated draw of 20c times pack size so say 2000mah would be 2amps. 2X20=40 amp draw, sometimes they tell you the burst too. Charging is 1c generally whatever the size of the pack is, so for the 2000mah charging should be 2 amps/hour.

Anyways thanks for the link to that sites, wish they had more hulls listed. But certainly some good info. I may do the renegade size but will try making smaller rigger first, hell it's not a lot of money to make an attempt, and I have almost everything cept the drive line stuff.
