I have a 35% Panzl with 4 x 5955 and 4 x 5985 servos. My Weatronic Rx has recorded AMP draws of 20A. 10 to 11 A occurs even in gentle flight like IMAC Sportsman. But those loads are VERY short lived. I have never seen a sustained load of more than 1/3 of a second. Average loads are still around 1.5 A for IMAC flying.

I like the HiTec servos - I never liked them in cars but in airplanes they work well. I am sure the torque numbers are exaggerated a bit but I have not noticed them fading in flight.

I don't doubt the 8711 numbers. I have seen those suckers suck batteries like mad in other airplanes.

A lot of it depends on how hard you fly too - los of 3D stalled flight with full throw and prop wash is going to pull a lot of amps.

I have noticed that in hot temperatures servos and engines and basically everything with an engine or motor in it loses performance.

It would be interesting to see how some older servos drop off like the 5945/5985/8411/8611 ... maybe the big motors in the new ones cause more heat and result in greater fade than the older ones?
