Hi! Newbie here, please bear with me.
I have built a F550 hexacopter with Ardupilot and Ublox GPS. I fly with a 5000mah 30C battery.
To cut things short, here's my problem:
First time I tried to fly it outdoors the darn thing doesn't even budge from the ground. My remote (a Devo7) says that I have throttle 50% and the hexacopter just wobbles slightly. If I increase throttle it looks/sounds like the motors throttle DOWN instead of giving more juice.
I tried this for 20 minutes and one time it almost tipped over (the two front motors giving a little bit more power then the rest) but this was solved (I think) with a all-at-once ESC-calibration.
But still, the darn thing won't move. I try holding it above my head and give it 100% throttle and it feels like it pulls slightly backwards, but still no lift.
I hook it up to MissionPlanner and go into "motor test", I put 50% and 2 seconds test and press "test all motors" and the freaking thing jumps up from the ground and flies two meters away - horizontally.
Yeah, I'm stupid to leave the propellers on while testing in MP, I know.
Sitting at home at my desk and trying the thing (without propellers on) I notice the following:
When my remote gives 100% throttle, the motors spin at a speed that is much much slower than when MissionPlanners tests the motors at 100%. Going by the sound of the motors, remote throttle 100% equals about 50-60% MissionPlanner motor test throttle.
THR_MAX is set at 1000 and I can't find any other thing to change.
Please... anyone? My already gray hair is starting to get white.
