Well now that the flaps are done I decided to do the aileron and elevator push rods. First I had to take a couple of weeks off for this bundle of joy. Say hello to my new aviator named Avden with his custom RV hat.

After getting the push tubes cut to length I needed to sand down both ends of the large elevator push tube as it was a tight fit. Chucking it into a drill was the easiest way with a sacrificial bolt.

Next it was off to the races with the drill press. I started with a #41 and then a 1/8" bit.

The dining room table has been taken over again for a little deburring. Hopefully tomorrow I will get to prime the inside of the tubes and maybe outside if I find the time.

Good to be working on the plane again after about a two week break.

Again, congratulations Jereme!

Work still chugging along for the machine! Awesome.

Slow going the past couple of weeks but still making progress. Finished up the pushtubes just in time for a bunch of family visits to see the new little one. I also started working on the FlyLEDs kit, pics coming soon.

Decided to assembly the FlyLEDs kit I received last year, I have been saving it for cold weather. This was one of the funnest parts of the build so far! I don't solder as much as I would like so this was a treat.

Here are the blank boards before trimming the main boards to fit the wingtip. An oscillating orbital sander made this trimming so easy it wasn't even fair.

Started by putting the strobe LEDs on the boards.

Next the small position LEDs were installed.

The large resistors were then installed.

Finally after bending the correct angle I soldered on the connector, this is different than if you had the full board kit, I'm doing skinny boards so I can install some squadrons as landing lights. (purchased before they came out with landing light option)

Next it was onto the control board. Started with resistors as per the instructions.

Then onto some various parts.

The last little pieces were soldered.

You can use a 9V battery to test everything and play around with what strobe pattern you want. I highly recommend this kit to anyone that wants some good lights at a great price and wants some fun in building!

I drilled my mounting holes too close to the internal circuit board and shorted out several LED?s. Paul at Flyleds responded almost immediately to my email and helped me troubleshoot the issue. He sent me two new LED?s and a few spares. Customer service is top notch.

Jereme,
Are you installing landing lights in the wing tips? Are those short boards for landing light clearance? That reminds me of assembler days at an engineering firm I worked at in Calabasas CA. Watching the crew do surface mount work, tiny tiny.

Great work!

Thanks for posting, so many people have good experiences with Paul that it was a no brainer where I decided to spend my money.

Yes I'm installing some Squadron Pro lights in the wingtips which is exactly what the short boards are for. FlyLEDs now makes one with the landing light option built in but I had already purchased the lights I have so no biggy.

Thanks, Carne! I couldn't find the order tab for what you have. Will spend more time today on it.

Well the weather has finally turned into a Wyoming springtime (30s) which means it's time to go full steam again in the garage! I'm looking forward to a productive work year, perhaps so good that I'll be flying at the end of it!

The firewall insulation has been on my mind lately so I decided to just tackle it and get it done. First I went through and drilled a hole mess of holes in the firewall for various things. I ordered in a piece 0.010" titanium from TMS Titanium, this was quite honestly cheaper than the titanium foil some people use and I simply don't like the look of the wrinkly stainless. I'm not done yet but I am glad I went this route, it seems very sturdy and when it gets riveted/bolted down I don't think there is going to be very much wrinkling.

First I cut the sheet on a foot shear. Cutting the sheet is for letting the fibrax below a path for off gassing in the event of an engine fire. Next simply trim them to fit on the firewall.

No you start marking the holes on the titanium from the backside. I then took off the sheets and went to town with a drill and this little guy (worth every penny of the $24.95 I spent on it).

I still have a few holes to finish cutting out of the titanium and after that I will start working with the fibrax. That's all for today though.
