Weight, balance and current draw

The target payload capacity is 50 kg, but it seems that might be far out of reach in the price range that we are considering. The Bergen Twin is capable of lifting 10 kg and costs nearly half of our budget. And the weight of the systems directly subtracts from the available payload, so keeping down the weight of all the components is important.

The components that have been identified are:
Current Mass Volume
Onboard computer 1 A @ 5 V 200 g 10 x 10 x 4
AHRS (PC Flight systems) 50 ma @ 9 V 400 g 18 x 10 x 4
GPS 50 ma @ 9 V 100 g 8 x 4 x 4
Servo controller 20 ma @ 5 V 40 g 8 x 4 x 2
Wireless card 200 ma @ 5 V 20 g 8 x 3 x 1
Camera (X-Cam 2) 78 ma @ 9V 100 g (?) ?
Batteries ? 1000 g ?
