I think this whole thread points to how easy it is to misread the plans even when reading over and over again. After five years of building my only advice is if you think the plans are wrong and the part just doesn’t fit, step back and take a break and then reread. Can’t tell you how many times I’ve thought the part or plans or both were wrong and my discarded parts bin reflects it

The solution is to mark the interference point on the tie-down and grind away the metal on the tie down bracket to allow for the dimpled skin. Just FYI, I am not the creator of this fix. Other threads have previously been posted on this topic with the solution.

Also, make sure you grind away enough metal to fit a flat squeezer edge in to squeeze the working end of the rivet

I did the same.

For the tri-gear, I dimpled per the instructions; but undimpled because it was not needed. It is clearly a flaw in the directions. There I am almost done with the Empennage and it is clear that they give less instruction as you move on in the project.

For example, look at page 10-27 rev 1. You will see the F-01414 Deck calls for a few flush 426-3 dimples; however, the bulkhead flange under them was never called out to be dimpled. I think you have to assume, that you have to dimple the flange. I also notice a lot of rivets are too short.

Just wanted to close this out with the response from Van's support. They confirmed that these holes are not dimpled/riveted in the tri-gear version and recommended that I flatten them out and build on.

I just finished undimpling those 2 holes to get the tie down to lay flat by using the squeezer to make them flat again.

By the way note that you will come across 2 F1037A parts you will find that they don't go anywhere in the empennage. Thought I'd have 2 parts left over! Save them they are part of the bell crank assembly in the fuselage kit.

The two parts are called "battery angles" (but nowhere near the battery) and are used in the tailcone as part of the structure of the pitch control rods and pitch servo.

Do you have a page reference for the battery angles in the empennage kit? Van's referred me to the pages in the fuselage kit and mentioned the bell crank assembly.

I think you guys are talking about the same thing. Page 36-06 Step 5 of the Fuselage instructions is in the tail cone and working with the pitch control rods.

Yes - part of the bellcrank assembly - it is physically in the tailcone but part of the fuselage kit, and installed in section 36, page 06.
