Goes horizontal after take off

[DevourU]

After take off, goes sideways and difficult to controll. Appears to be always the same direction. GPS is good on controller and drone. Controller appears to not have stick problems. Controll board replaced. Compass calibrated.
Help? TIA.

Are you flying in Smart mode or Angle mode?

Are the sticks reacting properly in Hardware Monitor?

Enter the Final Output display by tapping on the Volts readout on the ST16.


With the sticks centered CH2 should be at 0% moving the right stick left and right should cause the value to change between 100% full left to -100% full right (with the Rate Slider at full rabbit position). Move other controls and ensure CH2 does not change value.

Thanks for the reply. This in angle mode. Tried smart mode with same result.
I'll try to reproduce your results with Typhoon GUI and ST16 hardware monitor.

If you send some of the last flightlogs we could easily identify or exclude some typically problems. That may help in diagnosis.

The final output display is accessed by double tapping the Volts on the ST16. The aircraft does not need to be on to test the output of the ST16.

As @h-elsner suggests, your flight logs from these errant flights could give us a clue into the cause for this behavior.

CH2 is at -015% and is slow to zero, then goes -015%. Other controlls snap to zero and stay at zero.
This help from y'all helped me find this:

It sounds like a hardware problem rather than a calibration issue. I'm uncertain if you would have any luck getting electronic cleaner to penetrate to the inside of the control, but it might be worth a try. I'm guessing some dirty contacts on the pots could cause this. Guess the next step after that is look for and ST10+. I've seen them for sale at a very reasonable price from people who have totaled their Q.

Hello steve,do you have video on how to clean st10 sticks?kinda scary if i open it.

I'm gonna get some contact cleaner and try again. Stay tuned . . .

This sounds like a contact problem. Unplug and plug the connections on both sides sometimes to remove oxid from the pins. Try to clean the potentiometers.

Electronic contact cleaner into the aileron stick got it back to normal. Thanks for all the support.
