Servo Bus Voltage Spike

[nickyd]

Ive zoomed in on a voltage spike which shows the voltage dropping down to about 2volts for maybe a tenth of a second.

I never noticed anything like this before V4.02

Is this normal or something to investigate?

Cheers...

That doesn't look good....what BEC are you running? could be about to die

[nickyd]

cc 10 amp bec

I lost a heli beyond repair few months back due to CC BEC PRO dying mid flight....so im not using them again.

Check your wiring. disconnect and reconnect into the unit. make sure you don't have too long wires or any connectors between the bec and the unit.

after that - do some bench testing moving the collective fast and stressing the servos and check the voltage. i did some of the testing while connected than you can see the V in the GUI.

=] Nick, run a bench log (which we can now do) with "pitch boost" turned all the way up in a cyclic bank, and give the collective fast movements to see how the bec is holding.

but, really having seen a similar log yesterday with the same thing, could be a logging bug, but we have to be careful as Omer suggests,

DONT forget to turn the PB down!

cheers. will test and report back tmorrow

ok. bench tested as advised and no spikes.

Go for it. Fly far from yourself...
Check logs after first few flights
