Aileron / Flap / WIngtip Alignment

[Andy Hill]

In response to an RV-8 question, I made a post [Link] that others seem to agree is a good summation.

The same process seems to be good for the RV-3B, but may be more informative since the instructions are silent on some aspects of it.

My suggested sequence:

1. Fit Wings / Rear Spar attach to final drill
2. Align Ailerons using tool v outboard rib holes. RV-3 note: This tool is not described, but basically, using a piece of wood and AN3 bolts into the tooling holes in the OB Rib aft portion, align these holes with the Aileron TE.
3. "Lock" Ailerons using Bellcrank tool RV-3 note: This tool is not described, but make up a piece of AL with AN3 hole, onto each Bellcrank 2" (or 2.5") long (as stated in the drawings) from aileron pushrod against the spar surface
4. Align Flaps to Ailerons
5. Fit Fus/Flap Fairings to match Flaps RV-3 note: Easier to use RV-8 parts
6. Fit Wingtips and attempt to align with Aileron/Flap.
7. If Wingtip fitting not going too well, aim to align Outboard Tip of Wingtip with Aileron/Flap. Then "unzip" some TE of Wingtip, and use the fitting of the Tip Rib and some Resin back in TE to now align Inboard end. RV-3 note: This seems less of an issue than the larger RV-7/8 Wingtips.
8. Some creative artistry is now required to bend up the Inboard Flap ends to match the fuselage somehow...

It is a "homebuild" and some of the above will likely not all work [ RV-3 note: certainly! ] to the accuracy of a modern digital protractor Just do your best and hope the (small) errors balance out
