Separate batteries for Motors and APM

Started Apr 1 0 Replies

I've been worried about the APM browning out when the motor's batteries get low and it was suggested that is what caused one of my crashes.  Would it be possible to have two sets of batteries, while…Continue

I have a 3DR HexaCopter with the 880kV motors.  With the default settings across all PIDs, the copter lands without bouncing.  When I set the Rate D for Pitch/Roll just a hair higher ( .007 where the…Continue

"I've looked through my logs and it looks like I did the 2.9.1 upgrade around February 8.  I made about 6 successful flights using various modes before I had the first reset on March 7."

"Actually, by loading 2.9.1b the problem went away completely.  I made 2 11 minutes flights flawlessly.  If would like me to go back to 2.8.1, I would have no problems doing that if you would like."
