Post subject:  Heli wants to tip on its side with Spirit GT
Today I went to maiden my 700 Gasser after finishing the assembly, I started the Heli and when I try to take off the Heli will tip to the side and i can see that the swash is completely tilted, I restarted the unit several time with no success, my unit orientation is correct in the software, unit is in upright position with wires facing the back, my channel mapping is all correct.

I attached a picture of the setup as well as setup files and logs file.
Note that the vibration feels normal compared to my other gassers, I also activated extended processing.

Hello,

can you see when the problem appear?
Is it before spoolup or during?

Can you confirm that the compensation of the swashplate is working properly on the bench?

I checked the logs but they seem to be corrupted somehow or there is something very interesting happening.

When RPM is getting higher all readings are going crazy. Also all readings from receiver are abnormal once there are higher RPMs.
It seems as high voltage is going to the rest of the electronics.

Please make sure to route HV cable as far as possible from the rest of the cables otherwise it can cause crash and/or damage to the rest of electronics.

By HV cables you mean the ignition cable to the spark plug? It is far already, check the image. ImageImageImage

Thank you for the details,

I want to ask if you are running the latest 3.3.2 firmware and software? - because of the data in the log

Dear ZeXx86

I did another try today with the same result, i attached the new logs with 2 videos one showing what happens when engine is off and the other when the engine is running.
