If you guys want to know EXACTLY what is going on in your models, buy or borrow a Weatronics Gizmo receiver. This device records , amongst many other parameters, voltage and amperage at .1 second intervals for highly detailed analysis after your flight (s), rather like a quick access recorder as fitted to many fullsize jets. Real information, no more guesswork or assumptions !
This is an invaluable tool and has, for me, blown away many of the urban myths about power requirements for large model aircraft.
In addition, the 8 regulators are short circuit proof and divided amongst the servo banks to give a total delivery of upto 40 amps.
I have a couple of Airworld Hawks with multiple (11) JR 8711 servos, average current draw in flight is around 3.5 amps with very short spikes upto about 9 amps total, usually caused by large servo movements on the stab. or flap selection.
Need gyros? Just use the software to assign a gyro function to any channel from any axis !
