Post subject:  Tail drift counter clockwise JR nxb89g Glogo
Hi,

I did my maidenflight with my second Glogo today.

Aside from a continuous tail drift all went very well.

The tail servo is a JR nxb89g and I use a spirit pro which got replaced by Tomas - so it never flew before.

The drift starts after take off - I did two - so each time the same behaviour. I did check any trims on my Jeti.
After I land the behaviour is still visible and only stops if I unplug the battery.

Could it be a servo failure or has it something to do with the fbl unit? Anything I can do to provide more debug information?
On my first Glogo with different servos and a spirit pro this behaviour never showed up.

Many thanks! Andreas

Hello,

can you make sure that gyro is in Head Lock mode?
This is visible in the Diagnostic tab.

If it is HL, then please make sure that after disengaging throttle hold there is no trim. The trim could be set just for flight mode while for hold it might be OK.

The issue could be caused by a wrong initialization as well. It is very important that model is completely without any movement during initialization.

Yes it is. I compared all settings to my other glogo. Settings are good.

Checked everything there as well.


Behaviour of the Spirit changed while testing - it took sometimes now 30s until the Swash-plate did its "dance" - and yesterday evening it was constantly blinking (slowly).

This morning all unplugged only battery and usb-cable - I was able to connect one time - but not it is blinking again.

Really weird as yesterday morning all was fine.
