Hi everybody!
I've got a large 1280mm hexacopter, Multistar 5008 330Kv motors, 18x5.5 props. I've got it tuned pretty decent in stabilize, but in PosHold (Pixhawk running 3.3) it's slow and mushy when it brakes. While in PosHold, I think because of the large wingspan, the amount of time it takes to roll or pitch into the brake angle takes much longer than normal. It's kind of like I need to speed the rate of roll and pitch when braking in PosHold.
I've got PHLD_BRAKE_RATE set to default (8) at the moment, tomorrow I'm going to up that one digit at a time and begin slowly increasing I and D via Ch6 to see how it responds.
My question is with a copter this large, is there anything else I should be considering while trying to PID tune?
I've tuned many smaller quads and hexes, but this 1280 is nothing like what I've dealt with before.
Any help or feedback is GREATLY appreciated!
Dan
