Spartan quark

[Dardoug]

Got a relatively new quark prob bout a month old came from 450 onto gaui with a ds520 new servo connected up centring servo first and centring tail slider and now when switch between rate and head hold the servo travels in one direction and the quark is flashing blue twice which according to manual means no centre is found its starting to drive me mad now what have I done wrong along the lines? On a ff9. When dirt putti on trex450 it was just plug and play really!! I have centred servo before plugging into gyro and set all right angles?

It is reading a rudder input which often means you have not got zero trim on the rudder so check that first.

[Dardoug]

I've got all trims and sub trims at 0 that's why can't understand why it travels between modes?

Then check the servo monitor on your radio and make sure it really is showing 0 when the stick is centred.

If the rudder channel is getting any jitters that will also cause this.

Is it that the gyro is initialising before the reciever, try and switch it on normally and if it drifts leave the transmitter on and switch the RX off and on quickly and see what happens, i think it will then centre ok.
