  • 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.
