I have been flying a Phoenix extra 330S for some time. A couple of weeks back, the club instructor took it for a test flight and wrung it out. His remark was that the airplane did not recover from a spiral / spin when commanded- it did two complete spins before it flew out after neutraling the sticks. He pointed out that one of the elevator halves had a bit more play and that the deflection on one was more than the other. He was right, since putting a DLE20 on this airplane, I myself have not been too comfortable as the airplane snaps out of line at the top of a loop.

This is a dual aileron dual elevator setup with the pull-pull rudder. I am a novice to transmitter programming and I had someone else set up the airplane for me. When I decided to check out the trim yesterday, first thing I noted was that the two elevator halves neutral was not the same. I corrected the same by opening the clevis and turning them out till I got both the halves fairly neutral. Now, I am using 'mix' rather than 'ailevon' to link the channels. The elevators are linked using mix-2 with elev->flap, 'flap' being chanel 7. Now having neutraled the elevator, I noted that the elevator deflections at low and medium rates were fairly equal- within a mm of each other. However, at 3d rates, one elevator deflects 10mm more than the other. The one that deflects more is the master, so I cant reduce the throw from 'mix'. If I reduce from 'end point', I lose neutral as well as alignment at the other end of the throw and at low and medium throws. If I swap the channels over in the RX, I lose neutral again.

So what (the hell) am I doing wrong? I spent most of the evening trying to figure things out
