Default power consumption

how can i calculate the actual power consumption requirements when flying? is it a simple matter of adding up all no load mah servo power consumption specs? And if i add them up can i then come up with a reasonably sized battery?

Unfortunately, no-load servo current only applies when the model is sitting on the ground without the engine running.

The current will depend a lot on the servos you use and how you fly. E.g. my World T-34 with four s-148 servos will fly for a least 50 minutes on a 600 mAh pack before a recharge is needed. The current is probably around 0.5 A or so.

My Tai-Ji 40 with four 9304s and a 3001 will get maybe 30 minutes of pattern-style aerobatics from a 600 mAh pack and then I have to recharge. This means the average current while flying is around 1 A.

My helicopters with four digital servos need 2 to 3 A continuously while flying.

My 2m plane installs 4 digital servo, 1 normal servo and a 1500mah battery.
This airplane can be flown eight times as usual.
But, it consumes maximum current with snap-roll in a moment. When it does snap-roll, a receiver detects a voltage decline with about the third flight, and it is within safety recovery mode.
Consumption current changes by the flight conditions of an airplane.
