F-772 fwd bottom skin overlap

[FlyGuy65]

I understand the concept of having the skins overlap in a shingle type manner, allowing liquids to flow top to bottom, fwd to aft, and not enter the fuselage. However,...

The forward bottom skin F-772 would seem to fit much better being on the outside, not tucked into the side skins. Tucking it in creates a gap at the firewall where the side skins have to go outward to accommodate the bottom skin, as well as some poor fitting at the lower longeron/F-902 bulkhead area. Thoughts/comment from those further along? Plans are somewhat confusing (to me) as some drawings have parts omitted for clarity.

Thanks!

Take a peek at drawing 28.

If you look at the side view, it shows 772 as a hidden line, which implies that 772 is under the 770 side skin.

Thanks for raising this question. Guess what step I’m at?

Good luck continuing your build and thanks again.

I was convinced it went on the outside, then stumbled across that drawing. Then this afternoon I came across this: https://vansairforce.net/threads/rv-7a-kit-for-sale.225648/
(Classifieds, Rv-7a kit for sale if the link doesn't work). Fuselage pic clearly shows the bottom skin riveted on the outside. Now I'm just confused again!

Unfortunately, that's incorrect.

F-772 goes under F-770 as articulated previously.

Thin plastic cutting board to help it slide.


Manageable gap that will probably close up nicely when fastened. A little gooey stuff to seal firewall gap.

Good to go!

Hope this helps you!

Yes, thanks for the picture! I thought I was doing something wrong to produce that gap.
