Hello everyone. I hope you are all well.
I am putting together a large octocopter and have come across an issue. A friend purchased the parts for the octo based off a list I put together but OPTO ESCs were ordered by accident instead of ESCs with built in BECs.Unfortunately I didn't notice until now, due to having issues getting the motors and ESCs to fire on the octo, that they were they were OPTO ESCs....the APM would arm ok but the motors would not spin etc. I also ran the motor test in mission planner and the motors do not spin from there either. So I eventually narrowed it down, after many many hours, the ESCs not being powered.
I have not used OPTO ESCs before with the APM 2.5 so I was wondering how I go about powering them?
I believe in order to power the OPTO ESCs I need to use a UBEC or SBEC which must be 5V, how many amps should it be?
Where do I connect the UBEC/SBEC, does it go into a spare channel on the input side of the APM 2.5, a spare channel on the output side of APM 2.5, or into the Rx (I am using a Frsky DR8-II Plus).
And finally, with the UBEC/SBEC attached, should the jumper (JP1) be on or off the APM 2.5?
Thanks very much,
