On my 69 Twinkie I'm converting the yolks from standard Piper yolks for that year to Cheyenne yokes. A lot more buttons on the Cheyenne yolks but in particular I'm curious if the split electric trim switch will work or will I have to transfer my existing trim switch to the new yolks. I thought I may have read the electric trim switch was somehow propriety to the Stec 50 AP currently installed. I don't have a yaw damper.
