The last two days have been spent starting to put together my ultralight kit aircraft. I'm pleased with my progress; I currently have 19 hours in the build. When finished, my Chipper UltraCub will look a lot like this:
Yeah, you have to use some imagination to make that real plane. An engine would help. Also, a propeller, a windshield, a coat of paint, and some control systems.
My efforts this week are focused on the cabin and rear fuselage. Drum roll, please... here's some photos at the end of today, Wednesday.
What you are looking at is a cabin which is very similar to earlier ProCubs and UltraCubs from Belite Aircraft. Structurally, it is built from honeycomb aluminum and a lot of sheet metal. The honeycomb is used very smartly, using pre-cut strips, so very little is wasted.
I am providing the plans for this ultralight to my Patreon subscribers for $10 / month. Terms & Conditions apply. Here's the link: www.patreon.com/jameswiebe You can also indicate your desire to purchase a kit for $35 / month. I need the support, and I appreciate it very much.
Looking inside the cabin from the rear, here's the view:
The exterior width is 25", and I am 6' 2"+.
You can see that part attached to a bulkhead, in the below photo. Also note how my predrilled angles have been used to attach the bulkhead to side honeycomb.

Service Bulletin #5 Correct Wheel Alignment
This SB #5 is advisory in nature.
When assembling landing gear, particularly wheel assembly, take care to ensure that alignment of the wheels is correct. The lineup of the wheel should be straight to ground travel path; toe-in and toe-out must be avoided. Toe-in will cause landing gear chatter.
Alignment is ensured by correct rotation of the landing gear shaft before pinning in place at the upper bulkhead fitting.
The following picture shows correct alignment. The green line denotes the vector of the ground roll relative to the tire.

In this age of social media, I'm loving the way that I can connect my passion for aircraft with you!
I've been doing this in multiple ways: this blog, Facebook, email communication, patreon, Youtube, instagram, and now... drum roll please... an occasional podcast.
Well, it's really more like a video podcast.
In yesterday's very first episode, I explain some of the design decisions behind the Chipper ProCub / UltraCub, along with a tour of some of the FAR Part 103 features that the design has.
You can see and hear it on YouTube, here:
You also get to see my messy office.
I'm looking for ideas of topics you'd like me to cover. I'm looking for feedback on how to as interesting as I can for you!
