Hi *
I want to add a BEC into my Quad as I'm getting a marginal voltage from the ESC's onboard BEC. The ESC/BEC gives me 4.7 as measured on the APMv2 and I'm nervous of reboots and drop-outs, so I got a Turnigy 5V/3A dedicated BEC. Problem is, its measured open-loop output voltage it 5.27 volts. Normally I'd use this (I have some digital experience), but after a few dire warnings about not "over-volting" the APMv2, I'm checking here.
Is 5.27V too much? Will it take out the APMv2?
I'm aware of solutions like using a Schottky diode to drop the voltage, but I'd rather do it right than have multiple hacks.
Thanks!

With a 15R load (so 0.33A) the Turnigy BEC's voltage drops to 5V. What current does the APMv2 draw, please?
Hmm. This may be worth making a multimeter probe for. (Way make one? I'm disabled, with dodgy hands, and I don't trust myself to not short stuff out without having it unarguably in place!)
