Sorry about the length of this but I was trying to make it as clear as possible.
Alrighty then, let's see if I can explain.... I'm building an RV-9. The Fuselage instructions (page 8-13), under the section labeled "THE ELECTRIC FLAPS" has a list of procedural steps to install the flap actuator system. About the seven paragraph down, beginning with "Make the F-766B angle, the F-785B attach angle, the F-766D Spacer and the F-767 Attach Plate.", etc.
So I go to DWG 33 to check out all of these parts and there at the center top of the drawing is the F-767 Attach Plate. Only one problem, there are no dimensions except where and how to make the bend and there ain't one in the inventory!
Moving on.... the plans (DWG 33) call for two (2) F-758's to be used to attach the F-766A Flap Actuator Channel to the seat floors and the F-767 Flap Actuator Attach Plate to fasten the F-766A to the F-705 Bulkhead. Okay, I got the two (2) F-758's in the Fuselage kit but, again, not the F-767.
Then I looked at the separate plans and instructions that came with the flap installation kit (for an RV-6/6A I might add). No mention of an F-767 Attach Plate or the (2) F-758's, but they do mention the EF-603 and an EF-604!?? Both of these parts came in the flap actuator installation kit. I presumed that the EF-604 is to be discarded in-lieu of the two (2) F-758's but what about the the F-603? The F-767 is a much larger, beefier plate than the little F-603 and I would rather use the F-767. Luckily the plans show the F-767 in full scale so I measured the drawing and fabricated an F-767 out of some .063" AS that I had.
In conclusion (yeah!), my question is.... Has anyone else, building an RV-9/9A, had the same situation?
I think the plans that come with the flap actuator install kit are designed more for a retro fit into an aircraft that is already built with manual flaps.
Another question comes to mind. What if this were the situation with the LSA RV-12? You have to build exactly by the plans - but which plans?
