mQX acting schizophrenic
I haven't flown my mQX in a while, and I started to try again the other day and it did a number of odd things:
- On throttle up some blades would spin up then all would give up - On throttle up a couple of times one blade would suddenly race full speed while others did nothing - When it would launch from the ground it would be pretty responsive to throttle but barely to other inputs (slow to turn, slow to rotate) - When I brought it up to speed in my hand, not on the ground, it would sometimes go back to being its highly responsive self when flying I bought a couple new LiPos in case the others had gone bad but nope, that wasn't it. I see no burned out FETs. It's the total inconsistency which confuses me. Anyone know what's up? I don't know what needs replacing. |

Unfortunately there are a lot of possible reasons for that. I'd try the following:
a) Rebind as Pfloyd suggested b) When you're using a transmitter like the DX6i or better - check if the tx-setup is still correct. Maybe it has been changed accidentally. c) Have the motors been disconnected from the main board. If so, are they all connected correctly and are the rotors (CCW, CW) mounted in the positions they should be mounted. d) Did the configuration accidentally change from X to + mode? e) Also check the connectors of the motors. Is one or more of them sloppy or loose or corroded? f) One of the motors maybe weak. Hold her on one motor, add a little throttle and watch if one of the sides is lower than the others. Try this round robin with all the motors. Hope that helps.
