Okay. Ive got a new weapons and set-up, and updated the drive and batteries.

Drive: 2 S28-400 Magmotors @ 36v
Batteries: 4 x 36v NiMH, capacity = 3600mAh
Weaponry: A rear-hinged flipper powered by two 2kg Nitrogen tanks, each used seperately. (so I can use more gas)

Id like calculations for this please.
