Been setting up the Beastx unit on the 500 and it all works fine but it has a side to side tail wag I just cant get rid of. Its a torque tube tail with a DS520 on it.
I set the tail gain to 70% which shows up as light "G" on the beastx unit as the manual recommends, but when I bring it up into a hover I get quite a rapid tail wag of around 4-5cm side to side. If I increase the gain the tail wag gets smaller and faster up till 100% gain where it is only moving around 1-2cm to either side but very fast. If I reduce the gain below the recommended 70% the tail wag gets bigger and slower.
The wag only occurs in heading hold mode, not in normal mode which makes me think its the setup of the beastx not a mechanical issue.
Any help greatly appreciated
