Arducopter is limiting the total power output of my hexacopter to 37 amps when it has the potential for 66amps when at full throttle.I bench tested many different motor and prop combinations to see…Continue

"It could also be that multicolor is too heavy for the propellers/motors combination.  You might need bigger props or higher pitch or both.  I have a quad with 850kv motors and 11x5 props, 50cm motor to motor and it weighs 1300g all upp…"

"Default tuning is great and stable . But wont do flips and rolls . However  if that is what you like then  the stock settings are just fine . I only got into the apm because of the return to home after loosing a tricopter to 20 mph wind.…"

"Ditto on the raves for the APM.  I also was hesitant to upgrade from KK2 and CC3D but no longer.  My H-Quad flies perfectly with the default tuning."

"What you have is a simple enough setup, I have one myself. Reading through your post, and the replies, I can see no mention of doing an erase/reset after a firmware upload. Have you done these? The reason I ask is because the PID values do not look…"

"Well, it's certainly a tangential question..   I was just curious about how the motor was being limited--by voltage or current  (rpm, watts?)  Adding much larger props would cause the motor to obviously jack up the…"

"Question for you Luis...  I'd be very interested to see if the current usage goes up (significantly) if you change the props to couple inches over recommendations.  Do the motors just slow way down to keep pulling only 37amps or does…"
