SECTION 23: AILERON ACTUATION: Difference between revisions

Revision as of 03:27, 7 February 2023

In summer 2022, Vans could not source the correct push rod material for W1018A, so they sent out ones that are slightly narrower inside. The plans call for 4130 1/2 O.D. .035 steel tubing material (powder coated), the replacement had thicker walls at same OD, 4130 1/2 O.D. .049 tubing (not powder coated). A 7/16 reamer (e.g. $21 at Yardstore) is needed to make the AN490-HT8P (AKA VA-4908P) rod ends fit. The replacement rod material is not powder coated and needs to be primed.
It is common that the rod end doesn't easily fit into the push rod tube. Sanding is then necessary. See also this FB thread.

Part WD-421-R, the bellcrank, is used in several models. The RV-10 plans show it without nut-plate mounting holes for the autopilot servo attachment. Ignore those extra holes for the RV-10. See also this VAF thread or this FB post

Important: Read this VAF thread on rivet interference with rear spar. Aileron may jam in full up position if rivet has ability to be in contact with spar.
