Bug: Coax Mode ignores Ant-Gravity SetUp. Pitch Jumps Down.
Posted: Sun 03. Jul 2022 14:23:54
Hi, I have a Goblin 570 with Geolink and I set it up with one bank 0 only.
Steering between receiver and Spirit2 I'm doing via functions using the new channel selection modes in 3.4.
Transmitter is FrSky.
Bug:
I set up in the expert mode the anti gravity to 25%. That works fine.
Now I want to setup the Coax mode because I want to combine it with the Geolink "Position hold" and "Return to home" function.
When I start the coax mode via a separate channel setup, it works. When I activate the Coax, the swashplate goes down some degrees and the heli sinks unexpected.
I checkt it at home with the software. Then I found that the most difference is at full minus pitch and the less effect at full pitch when I switch between coax and regular mode.
I took the anti gravity value then from 25% to 0% for testing. The effect was gone. No jump of the swashplate any more. Taking anti gravity back to 25% the effect is again visible.
Then I switched in the software directly the bank 0 between Stabi normal and Coax mode by changing the Function field with the PC software. This shows the same effect, a jumping swash plate.
This shows me the the Coax Mode is generally not considering the anti gravity. This causes a jump of the swash plate down if you switch on the coax mode and has setup the anti gravity.
I have not checked, if other modes have the same bug.
From my point of view, this should be fixed immediately, because with high anti gravity values the swash jump can move the heli down to ground fast.
Best Regards
Bernhard
