New Build Tries To Tip Over Left

Maiden flight when giving a little throttle in stabilized, the quad tries to top over to the left. Attached is the log if anyone knows where to go look right away while I slowly go through it.

  1. Motors and propellers are correct. Really, they are lol
  2. No wind

What does it do when you give it a squirt of throttle to get it off the ground? I wouldnā€™t be the 1st time a timid application of throttle tipped the craft over.

Is that Ramp-up power default? Other than Low RPM Power Protect default settings work for most applications.

It tries even harder to top over left. Itā€™s quite pronounced. Ramp up is not default but I did try a few different percentages from 15 - 50% which made no difference.

Iā€™m hoping itā€™s just something simple I overlooked.

Iā€™m still skeptical even when someone says they ā€œtripled checkedā€ the Motor Order but we can only take your word for it that Motor Test in Mission Planner was done right!

haha I hear ya. But yes, spinning parts are correct.

When you Pitch and Roll the craft is it correct in MPā€™s HUD? A basic test I know and with a Cube itā€™s pretty difficult to get this wrong.

Roll and pitch are good. And just verified motor order again. :wink:

I just tried some setting changes in blheli_32 and looks like maybe I have either a bad ESC or something else wonky is going on. I didnā€™t try to take off but raised the throttle just a little bit. Iā€™m in a confined space atm. Take a look at the RPM for ESC 1. It races above the others.

Iā€™d hate to just ā€˜go for itā€™ and see what happens but that may be what I have to do.

Thatā€™s exactly what you have to do. But youā€™d best quadruple check that motor order and directionā€¦along with prop pitch orientationā€¦

Set the Blheli setting back to default with only Low rpm power protect off. Try setting the PWM frequency low to itā€™s lowest setting.

What Iā€™m also seeing in the logs is that the copter is (or thinks that it is) on a 2-degree slop/roll. If this is not the case and you place the copter on a perfectly level spot, try to calibrate the accelerometer before takeoff.
