I am 100% sure that this used to work, but having problems now.
My Flier ESC’s do not have 5 volt out, so I used to have an extra battery to power the Maytech receiver.
For some reason I’m not able to get this to work anymore
When I use an “old” BEC that does supply 5 volts all is working fine.
I think that I used to have the external 5 volt on the BATT+ and the MOT connector (see image below)
Anyone here who can confirm that this is the correct way?
