For the first time in several years, I returned to Oshkosh with the family. It just hasn’t worked out recently based on the Pandemic as well as Jeanine being in nursing school. Seeing the RV-10 isn’t ready yet.. we decided to fly commercially to Chicago and drive the 2.5 hours north to KOSH. It didn’t seem to make sense to take a connection flight to a closer airport seeing it was a short flight. The time waiting for a connection probably would have been pretty close to the same amount of time overall. Also seeing how many flights go into and out of Chicago, any flight delays/cancellations would be easier to deal with. We were actually delayed 2 hours due to storms and a ground stop in Chicago.. No worries other than arriving a little later in the afternoon then we expected. We rented a car through Turo and the owner of the car came and picked us up at the airport, drove us back to his house, and off we went. We’ve used Turo twice now and it’s worked really well. We rented a 26′ travel trailer from Kunes RV and had them deliver it to our site the week leading up to the show. We decided to do a water and electric site. We could have dry camped, but it’s just easier with AC and basic things with a 5 year old. Flying in commercially is tougher in terms of trying to get and use a generator. So water/electic site was it!

We spent part of the Sunday before the show at a park at Lake Winnebago. Swimming and there was also a large playground there. Declan had a ton of fun.

The show was a lot of fun and I think Declan enjoyed it. We visited Kidventure where we checked out some planes. Declan got to fly the RC airplane with help from the volunteers. He didn’t seem too interested in doing other activities there, but I feel like he’s still a little too young for some of them. In another year or two I suspect we might be spending a couple of days there. They have some pretty neat projects that kids can participate in.

We toured the hangars and Declan seemed to enjoy that. He walked to each sign in front of each plane and asked me what it said.

A big hit were the pedal planes. I’m pretty sure he tried all of the planes available multiple times over. He asked to come back here pretty much each day.. I would be tempted to get one of these kits for him, but he’s already pretty big for most of them, so it wouldn’t probably last that long.. Not to mention distract me from making progress on the RV-10.

This years show, for me, was spending some time engrossed in aviation with my family. It also served to meet several builders I’ve interacted with over the last several years. In addition, I made it a point to stop by most of the vendors I’ve dealt with over the years and put faces to names/emails/voices over the phone. I really don’t have a need for anything at this point to finish the plane, however I did end up spending way too much money on things I will need relatively soon. Below is the list

I bought a Best Tugs A3 model for moving the airplane around the hangar.

I also bought a nifty adjustable creeper for working on the airplane now in the garage as there are several things to do on the belly of the airplane. It’ll also come in real handy in the hangar. Not only for working on the plane, but for cleaning it too.

I purchased a travel weight cover and cowl inlet plugs from Bruce’s covers.

A purchase needed to finish the plane was a Halon Fire Extinguisher from H3R. I plan to mount this on the tunnel cover just behind the armrest near the rear passengers legs so it’s accessible from any seat.

With the Cold Air Induction sump there is a hose/quick drain setup to connect the Sump back to the engine seeing there is no internal oil connection like the stock Lycoming oil sump has. Tom has the below hose and quick drain setup to facilitate quick draining of oil for oil changes and connecting back to the engine with the 90 degree fitting shown at the top. These Lycomings have an oil suction screen in the cavity where that 90 degree fitting goes in the the rear of the engine. This is something that should be serviced often.. Having to remove the 90 degree fitting is a big pain because once the pipe threads are engaged and the fitting is clocked properly to connect to the hose, it’s very unlikely that you’ll be able to clock it back to the same spot each time you service the screen (basically every oil change).

Tom has proposed using this small screen that goes inside of the AN fitting and removing the suction screen all together. That alleviates the need to remove the 90 degree fitting at all. To service, it’s simply unscrew the hose from the fitting, remove the screen, clean, and reinstall tightening the flared fitting. These screens are used in racing dry sump applications. At least 1 RV-10 builder has beta tested this and it has worked out well. So Tom is now recommending these.

And last, but not least.. Sort of an impulse buy.. ZipTip Premiere wingtips to replace the stock Van’s wing tips. I’ve always eyed these things, but originally opted not to go that route. A few of the reasons I decided to do this were:

1. They are very sturdily made with no flex. I’ve seen several builders having to reinforce the insides of the Van’s tips to get rid of some of the flex.
2. The lights are not recessed into a cutout in the stock tips. They are practically on the leading edge of the wing and will be better for dispersing light more to the middle of the plane for landing at night.
3. They remove the need for a tail light/strobe in the rudder with the module having a rear facing position and strobe light on each tip.
4. They are much more aesthetically pleasing compared to the stock tips. The newer ones have a winglet curve shown in the picture below on a plane at OSH.

I spent a few hours today finishing the bend to the new elevator trim tab skins and fabricating small ribs (riblets) to close out the ends of the trim tabs.

I think they came out really well. The first one I did came out fine, but was a bit of a test on exactly where to bend on my marked line to get the proper part width/flange length. I then was able to bang out the 4 riblets that I needed to make. Two outboard and two inboard riblets. The outboard riblets somewhat interfere with trim tab horns, so I made the flanges a bit longer to share holes and ensure proper edge distance.

I took the following pictures to document the process.

All-in-all, I’m very happy with how they came out. These were really the first true part that I’ve had to fabricate from scratch on my own. It really wasn’t as hard as I had anticipated, and it’s satisfying to see it come together. I can tell already that I’ll be very happy with how this turns out compared to my barely acceptable bending of the tabs.

Since the last post, I’ve completed putting together the tailcone structure and match drilled everything. I’ve subsequently taken it all apart and deburred all holes and any remaining edges.

 

In the meantime, I wasn’t completely happy with how my elevator trim tabs came out, so I got new parts to re-do them. The 2nd time went worse than the first.

The goal here is to bend the tabs to close out the ends of the trim tabs. It seems like it should be relatively easy!

I didn’t have trouble bending the tabs on the skins, but these have given me trouble.

After messing up the first bend of my second attempt, I went off to do some reading on VAF. It seems lots of other have also had trouble with these tabs, so I guess it’s not just me. I also realized that I didn’t use any adhesive on the blocks so they moved slightly while attempting to bend the tab. Once I used some double-sided carpet tape, the next attempts went a little bit better. Probably passable, but I had already managed to crack the skin during my first bend.

The first set of trim tabs I attempted are shown below.

Below is yet a 3rd set of new skins for the trim tabs. After doing some reading, I’ve decided to do what others have done, and that is to cut off the tabs and fabricate small riblets to put on the ends instead. It might take me a few tries to get those correct, but I have lots of scrap trim tab metal to work with.
