I'm sure this question has probably been discussed numerous times on the forum. I'm really tired of wrestling with those upper hinge pins on my RV-6. And I would really like to investigate the possibility of replacing them with some more conventional fasteners for my RV-7. And possibly retrofitting them on my 6. Are there quarter-turn fasteners that have proven good on the RV's? Does anyone offer a kit?

Numerous builders chose this option. They make a total cowl kit and partial kits.
Firewall 1/4 turn. Cowl sides are hinged.
They have worked great on my -6 for 225+ hours.

Cowl fastners...
Two big companies:
Skybolt:

MilSpec:

any others?
I installed like the previous post and picture: 1/4 turn around the firewall, and kept the hinge between the haves. I think that looks best. Your mileage may vary.

Yep ..... for me it's the best combination of practical and aesthetics. Pulling my top cowl takes 2 minutes. (Yes, I've timed it.
) I used Milspec and have high praise for them.

Ouch... Unless you are building an F-16...
Oops. Got the wrong web site for the MilSpec folks.

I fixed it in the original post as well.

Definitely Skybolt
Skybolt offers prefabricated mounting flanges that saved me a lot of time and the professional look is much better than I could fabricate. I don't think Milspec offers the flanges. Get the flanges. As far as the sides, I went back and forth. Quite frankly, the tie breaker is that the fasteners look good on the sides and are functional. I see no restrictions to changing out the hinges on the RV6. Also, for bulging between the fasteners, I used another Skybolt product called Skybeam to carry loads around the firewall. An option is to glass in a bead of clear hose around the inner skin adjacent to the firewall fasteners. Either method works perfect to carry the load and is a no brainier to fabricate.

Used the Skybolts for the top cowl along the firewall and the sides. For the bottom cowl, I used #10 flat head screws with washers into nutplates. You have to look pretty hard to see the difference. Pulling the top is really fast, and the bottom, when I have to do it, doesn't really take long either.
