Taking elevator servo off

During first 8 flights in one day I realised that I did not change tail angle much, and bird flew well. Also tail was pretty wobbly and shaking a lot during flight, because linkage between elevator servo and ruder servo had to much free play. So I temporary took elevator servo off and set fixed tail angle of attack.

After that I made four flights with my yellow bird, and all was fine. Bird was lighter 2 g because of 1 servo less.
