nano qx problems
Hi
I have just got a nano qx and dx7s controller. Everything was fine after calibrating and setting up. A few nice flights. Now its flipping forward while trying to take off.. Its like the yellow probs dont spin properly. If i pick it up and angle the nano different angles the props start firing like its trying to stabilise or something. I have tried, resetting the transmitter settings Any ideas? |

nano qx problems
Check for hair or lint on the motor shafts.
When you plug the battery in,before bind is it on a level surface? |

ok the plot thickens.
I just managed to have another successful flight. Dont know why but it just seemed to take off again. battery then died. So replaced the battery on the Nano QX and then seemed to have to re-bind it to my dx7s. Now same problem again. 2 props not spinning properly causing takeoff to be impossible. |

I would contact HH, sounds like a bad board.

If you took any blades off, are you sure they were put back on correctly? Wrong blade placement could be causing the flipping you refer to.
EDIT: Just saw you had a good flight after the flip flights, so the blades must be fine. Last edited by ronj; 12-21-2013 at 09:13 PM.. |

Did you make sure you put it on a level surface right after you plug in the battery? It calibrates "level" every time it initializes. If you plugged in a battery and held it tipped forward while it initialized, then it would act like that when it was level, it's trying to find the angle it thinks is "level".
And btw, this is the Nano CPx forum. Most of us also own an Nqx so we didn't notice.

I too am having the same problem. I cleaned the shafts one at a time as to not mess up the props. Also I bought extra batteries and i noticed that the new ones were 45C not the 25 that comes with the Nano. And I did run two of them at least before this problem. Could this be exchanged for new?

you have to put it on a lvl surface before the light goes blue

Most likely the sensors are thinking the quad is in some degree of bank or turn and trying to get there, even though it's sitting still...
Try re-binding, that should set the values to zero again If the quad lands suddenly, it probably remembers that bank angle and keeps trying to get there until it gets another command |

I don't have a NQX but I would try to move the motor cables to the opposite plug and see whether the failure moves along. If the front motors run properly from the back plugs the board is faulty (the FETs?). If not, the motors are bad.
BTW... It is a hoax that gyro stabilized items require level. At different temperatures and while any movements the gyro system emitts different voltages which are detected and analyzed by the stabilizing system. If there weren't different voltages at different temperatures the initial phase wouldn't be necessary at all. While the initializing process the system checks the actual voltages and does a zeroing. The new zero is the point where the system assumes it doesn't have to counteract any moving. "In flight" the system always tries to maintain zero voltages. Zero voltages happen on "no movement" and "no movement" happens when the copter is level. So it levels the copter by itself all the time. The angle while initializing does never come into play. |
