Hey Guys,
I thought it was about time for an update on the Carbon Cub. I spent 3 weeks at Son Trey's house over Christmas. As you can see we got quite a bit done. The Cub is starting to look like a real Flying Machine. We installed the wings, flaps, ailerons, and the big pain the the fitting of the windshield. A bunch of small items that take forever to do and when finished it looks like nothing was done.
Most of the final finishing items SHOULD go fairly easy..
As the little doggie said when it got it's tail caught in the door" It won't be long now" :)

Since it is painted Red White and Blue like all of our planes the name for this one is "Patriot" That way if things don't work out the way it should. It will become known as "Traitor"

Looks awesome! Do you buy everything in a kit form, or just figure out which pieces will fit and buy them separately?

Then once it’s all done, how do you test it before flying? Know what I mean? Like how do you know it’s airworthy without risking a crash?

Really cool though. Great job!

Looks pretty darn good, Jim. I am really airplane stupid, but is that a 4 cylinder engine w/4 valves per cylinder or an 8 cylinder? I also second Kevin's question, who flies it first? How do you know it is 100%?

"What makes the windshield so much fun?"
I will try and explain what goes into installing this POS windshield and will probably forget some stuff. :)
First after drilling the holes and painting you position the mounting strip /MS that you see next to the blue tape onto the boot cowl. When you think it is in the correct position then drill holes into the boot cowl /BC and temporarily attach the MS to the BC Now you are ready to fit the oversize windshield/WS by putting it on the BC without the MS on so you can see the drilled holes in the BC and the ones in the side post and on top of the airplane frame. In the picture you can see the side frame screws.
Now that you have pushed and pulled the WS into place you mark where you want to cut the WS with the die grinder with a thin cut off wheel on it to fit the MS. This will take at least 4-5 fittings. Remember measure twice cut once WS is high$$$. OK WS fits MS now mark to be able to cut for fit of top and side frames. Next we mark and drill the PILOT holes in the top and sides. Then drill oversize and camphor the holes. Temporally put WS back in and check for fit must fit in WS tight. Success it fits now you can take everything apart to allow you to drill larger holes and install threaded inserts/Rivnuts into the BC for the #6 screws that attaches the MS. Install 2 sided tape to the MS and install the WS then remove 1 screw at a time to allow you to pull off backing of 2 sided tape. NOW we can fit the SKYLIGHT at the top and install screws on side post and top.
If you are lucky this only takes 3-4 days and you don't need to order a new windshield or drilling a hole in the wrong place from being stooopid. :)

Kevin,
This EX-3 Carbon Cub comes in a kit with MOST all parts to assemble. BUT you still have to fabric cover and paint all of the parts. Another BIG PITA but Trey and I enjoy doing it when stuff goes right:) Sometimes the impossible just takes a little longer and to show the non believers it can be done.:)

The flight testing begins after you get your two size extra large big balls on. Climb in fire that baby up and see if it will fly.

Really most of the similar homebuilts have flown in the past and will fly you just don't know how well. You and others spend quite a bit of time looking at all of the important parts. If the engine keeps making loud noise most of the time all goes well.


This is what happened to my neighbors DR-1 Tri-Plane. This was on the first flight and due to engine failure and the pilot, not the neighbor, having his head where the sun don't shine. A real shame6 years or so down the crapper and $150K+- along with it. It was also an outstanding build

Turd,
It is a 4 cylinder and fuel injected with 2 valves per cyl. which makes about 200HP on 360 CI

Trey will fly this one first. The other EX-2 Carbon Cub we did Chad flew it First. I flew my Starduster Too on it's first flight in 1973.

Chad and first flight 2019

Very nice, and thanks for the info on the engine and the excellent description on the WS installation. You guys have my utmost respect for the work you do.

I've always wanted to fly and I knew I would have to build anything I could afford like everything else I have. So far I've been sidetracked with cars, trucks, bikes, guns and boats. All 40 years worth still less than 1 plane. I've seen hovercraft with wings that can cruise 20' or so off the ground. I might have to settle for that.
