Hi.
I have mounted the elevators on the stabilizer to complete fairing assembly. The forward edge of the elevators are rubbing on the stabilizer spar, most notably on the stabilizer attach brackets.
To remedy, I have:
1. Contacted Vans. Answer: Perhaps you will need to remove rivets on the elevator forward skin bend, tighten he bend and re-rivet (new holes). Did not do this.
2. Added additional rivets in between current rivets on elevator bend to hold shape better. Seemed to help a bit.
3. Worked to form the elevator forward bend radius from circular to more of a "D" shape (flatten the curve). This helped a bit.
4. Checked, re-checked and adjusted rod end bearings from print 13/16" nominal to 7/8" nominal (7/8" is max length called out on the RV-9A). Helped somewhat.
All these items helped, but still slight rub on the stabilizer attached brackets.
Any other ideas? Anyone else seeing? Does anyone have a spar to spar measurement that I can double check against?
Thanks
