I've had a long-stanidng saga with a GAUI EP100 SE Pro that loses power, and the AR6200 (with QC) indicates a power failure.
I'd assumed this was down to the motor drawing too much current. Having lowered the gearing a lot, and still seen the problem I was getting sceptical about that. Today I tried to eliminate a few things, and doa serious debug session.
The notes are below at the bottom. You may well not want to wade through them, unless you want to get the detail. Here's an 'executive summary':
With no blades; a flat (no lift) pitch curve; no gyro/tail servo connected; ELEV & PITCH swash servos connected:
With either the installed AUX1 swash servo, or a brand new (same) servo pluggd into AUX1, it won't spin up properly.
With nothing in AUX1, it spins up fine.
[I've not tried AUX1, but nothing in ELEV, etc.]
The servo in AUX1 isn't being required to move.
Any ideas ?
The only thing I can think of is some kind of problem with the power routing in the AR6200, such that plugging into AUX1 causes an intermittent short, or an intermittent break in the power feed to the Rx. (?)
(Too Much...) Detail below:
[[[
Flat blades
Constant flat pitch curve (no lift)
Won't reliably spin up/stay spinning on bench
Remove blades.
Still won't reliably spin up/stay spinning
A lot of tail torque. Hold rudder stick so not there.
Still won't reliably spin up/stay spinning
Swap ESC & battery.
Still won't reliably spin up/stay spinning
Disconnect gyro/tail servo
Still won't reliably spin up/stay spinning
Slacken tail belt a bit – to be sure.
Still won't reliably spin up/stay spinning
Disconnect 3 swash servos.
Spins up.
Reconnect all 3.
Won't reliably spin up/stay spinning on bench.
Disconnect AUX1 servo (front l/h).
Spins up
Reconnect/disconnect a few times. Spins up properly only when disconnected.
Plug another (new) servo in AUX1.
Won't reliably spin up/stay spinning on bench.
It seems possible on one or more occasions jiggling AUX1 connector allowed to spin up.
NB, not tried with AUX1 in, but ELEV removed, etc. (ie related to # servos).
NB flat pitch curve, so servos not moving as throttle increased.
