I know the design of the other RV's necessitate a protective tape as they are always in contact with the upper skin in any position. Just curious what other RV-10ers are doing, bending the top skin trailing edge slightly, or adding a protective tape? Thanks -Mike Sent from my iPhone ________________________________ Message 2 _____________________________________ Time: 05:28:14 AM PST US Subject: Re: RV10-List: Flap Question From: Seano I put the protective tape on the underside of the top skin instead of the top of the flap. This way it still doesn't get scratched and the uv doesn't yellow it.

My thought was that anything getting stuck between the tape and the skin will scratch the underside of the wing skin, not the top of the flap.

But a customer had his tape on the top of the flap. After a few years the tape got brittle and began to flake off. He was complaining about a significant rolling moment when he put the flaps down. I'd seen that on my plane because the flaps were initially a little out of rig, so that's what we looked for. The rigging was fine so we cleaned up the flaking tape and that solved the problem--no more roll with flaps down. --Dave Saylor On Sat, Apr 21, 2012 at 5:15 AM, Michael Kraus wrote: > > > > I noticed my flap leading edge hits my wing top skin in the fully up > position just barely.

I wonder if it would help or hurt performance? I think the flaps actually depend on air flowing from the underside of the wing to help with airflow. but maybe not? I am not an aeronautical engineer nor have I tried anything.

Flap effectiveness would decrease significantly if the gap were sealed.

Lot's of edges and holes. I expect the stainless firewall won't stress crack like 2024T3 will, but I'm unsure. What's the bottom line??? Thx, Rick #40956 Southampton, Ont ________________________________ Message 11 ____________________________________ Time: 08:47:30 PM PST US Subject: Re: RV10-List: Firewall From: Rick Rick, Yes but for several reasons. One is it will cut the crap out on you in the n ormal course of the build. Second, although it's not as prone to stress crac ks as aluminum, smooth the edges to prevent any chance of stress risers. You can be much more aggressive than aluminum. I've found Dremel sanding barrel s and carbide cutters work well. Time spent smoothing these edges will save m any bandaids and painful steel cuts over the long run. Just my humble advic e, worth everything you paid for it. :D Rick Sked Building RV-10 n=C3=BAmero dos!
