I got to the point where I had the horizontal stabilizer and elevator ready to skin, but had to wait until I received a visit from the EAA Technical Counselor. He stopped by Wednesday and had a look at the bones and was impressed with the work, so he gave me a good review.
​Now I can go ahead to close them up!

I've been reading some other blogs (Peter V's and Jim's) that have provided some good tips on what to look out for while closing things up, particularly to look for any twists. So I cleco'd the skin on the horizontal stabilizer and drew the line down the center of each side. I then placed the frame pointing upwards and attached a string from the leading edge with a weight to see where the line differed from the string.
It turns out I did have a slight twist, so I'm in the process of moving clecos around to 'pull' the twist back into alignment. Once I get things into alignment, I plan to use the clamping method mentioned on Peter C's blog to make sure the elevator matches the horizontal stabilizer.

I was able to finish up the Horizontal Stabilizer ribs and dimple the rest of the skins. I pulled the wire through and now I just have to apply the skins and make sure everything fits again.

It's feeling like déjà vu, cleaning, degreasing and priming the elevator parts.. one of my least favorite activities of the build process, but necessary. At least now I'm getting a streamlined process down.

I primed the elevator parts and let them dry for a day. Came back to it and started riveting!
This assembly is definitely a bit more complex and took a bit more time to study the instructions.

On the swing arm assembly, there's a hard to reach rivet right next to the bracket. You'll see that one missing in the photo. I figured I just get some small M2.5 hex bolts and stack them about a quarter inch until it is flush with the nose of the rivet gun, then give it a pull. Worked like a charm!

I did find some discrepancies in the instructions with rivet sizes, seems the descriptions of the rivet sizes are different and different parts provided in the kit than referenced in the instructions.

The description in the instruction says it is a 3.2x13.6mm Alu Domed Rivet, but the actual rivet size received with the part number in the kit is 3.2x12mm. Additionally, the instructions say to use 4.8 x 12mm rivets HW-RIV-164-X-X-0, but the kit for elevator parts only includes 4.8 x 15mm rivets HW-RIV-165-X-X-0. I made sure that there weren't any other locations needing 4.8mm rivets and went ahead and used those.

And of course, while feeling like I was on a role, fate seemed to occur. While torquing the bolt on the swing arm assembly, the bolt actually snapped off. Now I have to source another AN3-13A bolt and take another look at the torque required.

It's ok, I'm sure it's not going to be the last 'oops' moment and I just look at the new shop sign from EAA - "Keep Calm and Build the Plane." ;-)

I also ran into an issue with the bracket that connects the swing arm to the ribs not being aligned. I checked with TAF and they said to just drill up a size and use a 4.8mm rivet. Seemed to do the trick.

On another note, I did add a tab with a chart for my hours by category.

It finally felt like I made some good progress today!

After spending hours dimpling, cleaning, degreasing, and priming.. it finally came to the point where the parts were ready to put permanently in place.
​
It was a bit nerve wracking the pulling the first rivet, I must have checked the plans at least 5-6 times to make sure I knew exactly what to expect. Of course, after a dozen or so rivets, things got into a good rhythm and I started to trust myself. The Milwaukee Rivet Gun makes this process really easy, great suggestion from other builders!

I was quite happy that there were only 5 or so holes on the rear channel that needed to be enlarged with a chucking reamer.. just off by a hair. Enough the rivet couldn’t easily drop in.

It also helped that I had my project manager and quality control person keeping me on track. Thanks Son! Our flying adventures are still on track thanks to your motivation. ;-)

I did find out that I forgot to order the right sizes countersink bit. As soon as that comes this week, I can finish up the ribs and work on applying the Horizontal Stabilizer skins.

While the rack of ribs were on the grill for the 4th of July, I had some free time to get some more work done.

I'm following the method that others have done. (Other blog links on Resources tab)

1. Initial Assembly. This is a temporary assembly in order to see if I’m missing any parts and to figure out the build order since there are no formal instruction steps.
2. Disassemble.
3. Clean Parts. I use Simple Green Extreme aircraft cleaner 1:1 ratio and scrub with a red 3M ScothBrite pad.
4. Degrease. I used Acetone (wear a respirator and gloves). Don’t touch with bare hands after this.
5. Prime. (wear respirator and gloves) I use Rust-Oleum Self Etching Primer (mainly because it's easy to source), 2 light coats.
6. Let Dry. The longer the better, but at least 24 hours.
7. Reassemble.
8. Double check the Plans.
9. Rivet.

I was able to get as far as getting a single primer coat on before I had to do some more food prep and, well, my can of primer ran out. Definitely need to grab a few more tomorrow and looking to finish up the Horizontal Stabilizer this weekend.

Also, I put an order in for the RAMI AV-12 VOR antenna, so that with the position light I already purchased, I should be good to go for the empennage electronics perspective.

Now that I have the C-Frame, I started dimpling the horizontal stabilizer. Overall, it was a pretty quick exercise to dimple the ribs and spar, only a half hour. However, the spar is pretty thick, so it took a few extra wacks!

I wasn’t sure about the quality, so I had my helper check my work and he gave me the thumbs up!

Next up is dimpling the HS skin. Will get to that tomorrow!

Well that was a task.. using some Simple Green 1:1 mix with water with a red Scotch-Brite scuffing pad took quite a while! I focused mainly on the areas that would be a ‘mating’ surface and that still took close to 1.5 hrs.

The water sure did get dirty as you’ll see.. the aluminum ‘looked’ clean but I’m sure it goes through plenty of machining before it gets to the final product.

As I saw on another blog, I removed the blue coating on the skins by using a heat iron. Simply run it across the coating and it will peel off! Now no need to worry about extra scratches on the skin until I’m ready to finish.

Next up is making absolutely sure there’s no grease on the parts by using Acetone prior to priming. Maybe I can get the wife to help me next time for an extra set of hands? 🤔

I asked Barry for an update on the Quick Build progress and estimated ship date.
I put down my deposit in mid-March and was expecting shipment to be sometime in July.

Unfortunately, I received word from production that the wing delays from earlier this year has still had a lasting effect on all of the builds after that. They mentioned that they could push delivery forward by about a week or two, so it's looking to be closer to the first week of August for an estimated ship date. Then it'll take a few weeks to travel by boat from South Africa to a US port.

I'll be anxiously awaiting another update and hopefully I'll get some photos of progress in the mean time.

I spent some time this weekend thoroughly reading through the manual and decided to give the horizontal stabilizer a shot. I wanted to make sure all the parts fit and see where I might need to do any match drilling.

To my surprise, it came together rather quickly!

For someone who hasn't done this before, reading the instructions the first time, I put together the HS in about 2 hours from start to finish.

Putting on the skins, I identified only a few areas where it might get tricky, but I don't think I'll need to do any match drilling. Most of the holes lined up perfectly!

Now that I have a good idea of what needs to be done, I'll be disassembling and getting the parts ready for dimpling and priming.

I ordered a C-frame dimpler and should arrive next week.

I also set up an appointment with a local EAA Technical Counselor to get acquainted and start the process.

I took my 7 month old Co-Pilot and Wife to the Livermore AOPA Fly-In today.
It sure was hot out there, but otherwise, great flying weather.

Was happy to see N135WT again and met up with Wayne (the plane’s owner) and Jean.

Really cool to see other planes out there you only see in magazines. Draco, Velocity aircraft, Barracuda, RV-10 and of course the Sling TSi. ;-)

I'm so excited to finally receive my first shipment!
It's starting to feel real - it's been 3 months since I put down the deposit for the kit.

Now the fun begins...
I spent the first hour or so reorganizing the garage to create a workspace.
Then finally cracked open the box and started the process of inventory. Checked off all those boxes!

Now things are neatly organized by tail section, I am shopping for the ILS/VOR antenna and the tail position light.
I went ahead and purchased the Aveo ​PosiStrobe MiniMax™ DayLite Red.

Still looking into the antenna options.

Now to educate myself on all the different priming options!

After months of research, I decided to pull the trigger and put down the initial deposit on a Sling TSi QuickBuild kit!

The Sling TSi seems to hit all the sweet spots:

• 4 seater
• Fast
• Efficient
• Modern Avionics
• 'Oh Shit Handle' - a.k.a. Ballistic Parachute

I've received initial estimates that the Quick Build will take approximately 3-4 months. That would put the container arriving sometime in June / July.

I've been coordinating with Barry from the Airplane Factory in Torrance to schedule a demo flight.
After months of research, I'm super excited to visit and get to see the plane in person.

While we were there, I was able to see a Quick Build kit in it's raw form from the factory. I was surprised by how much of a complete kit it already is! The fuselage and wings are basically put together for you. I was seriously tempted to jump in and start making airplane noises... ;-) Luckily, I had the real deal right next to it - N135WT.

Barry and I had a quick flight just off the coast and I the handling characteristics were great. We saw 1,200+ fpm on climb out. Once over the water, Barry handed the controls over to me and I felt like I was in a fighter plane, it was really responsive! Cruise speeds were as advertised, even at lower elevations I was seeing 135 kts indicated and true airspeeds of 145+ kts.

I took a few pictures and videos and stitched them together to remember. It certainly was an epic flight!
