Your progress looks great. It is starting to look like a nice plane.
Looking good, it has that Pattern look. I can't wait.
Here is a link to a recent video of a Pattern aircraft, you can see it has the classic pattern moves and looks like it is "flying on rails": https://youtu.be/V7Yr1vyuJAU

We'd love to see you complete this.
I took a look at it the other day. It will be easy to resume. Just need to get some time. I thought I might get to it today, but I still have other priorities. Things are settling down fast since my return, just not as fast as I anticipated. Sometime within the next few days I will be able to give a solid progress report.
Thank You.
Thank You.

Hope you can still look at this soon. Very interested in what you come up with!
Sorry, I keep getting sidetracked. Life and all. I will have some home time soon. We will see what I can get done.
Here is a Maker Foam plane patterned after the Super Kaos Jr. I did not use an FT style power pod. Motor mounting will require some modeling ingenuity or you can use the 3D printed motor mount that I used. This used the FT Radial "C" pack motor. The servos were some 9g metal gear that I had laying around. A 9x6 prop, and a 4S 2200mah provided loads of power. The PDF plans, the motor mount stl file, and canopy stl file are included below.
This plane flew excellent. Sorry for no video.
If you decide to build one, let me know if you have questions.

Tommy, wow, looks really great! Thanks for doing this!
Are the two parts on the top of page 1 ailerons? What is the small cut out next to them under the measurement reference? What are the two cut outs on the side of the fuselage? What are the two mirrored pieces on page 2?
Sorry for all the questions.

Very cool! Those ailerons look really big. Are you looking for 3D like performance?
Not particularly. The idea was trim to desired effect. But, at that size, the plane did excellent snaps. Nice clean and crisp.
The two parts at the top of page one are the ailerons. I did not mark left or right because once the wing is built, it is easy to match up the lines.
The small cut out is a flat plate that tabs into the slots at the front of the fuselage. It gives a nice flat surface for gluing a motor mount.
The two cut outs at the front sides of the fuselage are for the tabs on the motor mounting plate.
The two mirrored pieces on page 2 are fuselage doublers. Once you fold and glue the sides with the top plate, glue in the doublers. Then glue in the bottom plate. Now that the fuselage is sealed up, time to make the cuts for a removable wing.
Let me know if you have more questions.
I know there are no servo cutouts in the fuse. That placement is subjective. Use your servos to help achieve CG.
CG is at the back of the spar.
You will also need to eyeball the placement of the wing hold downs. Use a skewer at the front and rear of the wing, somewhere centered through the doublers.

Tommy, thanks for the information! Could you possibly post some pictures of the tail and bottom? Thank you!

I'll send picks in a bit.
