I come to consult the Oracle!
I'm hoping someone out there can shed some light on a possible issue I have with my quad. I just tore the stock quad apart (was flying perfectly!) to install Tarot 2D gimbal w/ Gopro, video transmitter, and MinimOSD on screen display. I've installed everything and it functions as it should (OSD, gimbal, camera pitch RC control, etc)
When I'm testing it (haven't flown yet), the #1 motor ESC gets VERY warm (motors are off). Not sure if this was an issue before the installation of all the equipment, but I definitely notice it now. When I'm looking at the OSD it shows between 1 and 2 amps with motors not armed. This is through the 3DR power management doohickey. I've tried my best to "calibrate" using a voltmeter and adjusting the voltage divider in APM. The stuff drawing power is APM, gimbal, Gopro, vTX, OSD.
#1: The consumption seems high which can be attributed to the Gopro charging. I've tried with a fully charged Gopro and it's around 1.5A, motors off. What are others seeing as their "standby" current? Is my power consumption normal?
#2: From what I've read about the 3DR power distribution module, it has it's own 5V regulator so it's not pulling from a BEC somewhere else on the quad. Is this correct and 2nd part would be, why is the #1 ESC so hot (the others are cold)?
3DR Quad c-frame
880KV motors (11x4.7 props)
4000Mah 3S battery
1W vTX - 12V Directly from battery
MinimOSD - 5V powered from 3DRs PDM / 12V powered directly from battery
Tarot 2D gimbal - 12V powered directly from battery
Gopro 3 Black - 5V powered from 3DRs PDM
I apologize in advance if this is the incorrect forum and accept the public flogging that will insue.
Thanks for any and all help! :)
