Default RE: How to test total amp draw under load?


ORIGINAL: pilotpete2

I hafta ask, what is the number and type of servos you are planning on using. The Idle and stall current is usually published for the servos, receivers also have a published current drain and is usually insignificant.
Pete
am running : 1 JR ls4001 (older and don't even know the pecs) for throttle
4 Hitec 625MG's 2 on ailerons 1 on elev 1 on rudd
Spektum AR7000 revceiver
JR heavy duty switch with charge jack (18ga)

idle and stall current specs mean nothing in this case though because published stall definition (according to Hitec and for that matter ALL manufacturers) is at no load.Meaning nothing connected to the servos ie:control rods,control surfaces,and really doesn't give you a proper idea of what the actual current drain would be under flying conditions to give you guidance as to what you should be using for power.

So what I was hoping to do was create a worst case environment, take some draw readings both in extreme (3D) and normal flying conditions
