Earl has just the one thread. He's an excellent builder with the skills to build that huge Rascal.
I'm thinking that a 10' Kadet Senior Sport might be an interesting project.

My wife's Kadet
These are some pictures of the Senorita I built for my wife to learn to fly on this spring. I modified the kit slightly by reducing the dihedral and adding ailerons and moving the vertical stabilizer back. I also added mounts inside the fuselage to convert it to a tail dragger later. It's powered by an OS FS .26.
It fly's like every other Kadet I've flown and looks great in the air.

I agree, I love those two colors together. She is gonna love learning on that bird.

KaP2011, very nice looking bird - your wife's gonna love flying it. Gotta ask though - out of pure curiosity, why the tail change? Any particular reason?

My wife loves to fly the Seniorita in the RF 7 simulator so I decided to build her one like it, hence the reason for the ailerons. My first flights were on a 3 channel plane and it was difficult to transition to a 4 channel plane. I did not want my wife and grand-daughter, who will also learn on this plane, to have that problem.
My wife chose the colors, I chose the design. She wanted to name it Bonita.

I finished clearing the workbench this evening and started setting up for the build. I love the feeling of starting a new project and all the possibilities for "improvements" running around in my head. For this build I plan on making the LT25 look a little like a bush plane with different wheels and gear. I would like to share as I go and right from the start I have a question of any engine aficionados who might be willing to share thoughts and or experience with one of my first decisions.
My last LT25 had an OS 40LA mounted on the front, it was so close to being able to hang on the prop. I absolutely loved the extra power and I am not willing to give that up.....however.....I recently aquired a Magnum 32ARNV which according to the donor has special porting. The 32 had a Macs one piece muffler which is supposed to boost power (it coincidently fits on the 40LA which is another possibility). The question would be if anyone has an opinion on which of the two motors would produce the most pull? 32 with special porting and Macs muffler or 40LA with same Macs muffler. Additional consideration is the weight difference of a couple oz. I,m leaning towards the 40 for the bigger displacement and ability to swing a bigger disk. I have a feeling the 32 has the ability to produce more rpm though.
a few hours work and I have this

No one yet commented on the motor question, no matter cause I have decided to go with the smaller engine to save weight along with the MACS muffler. Due in no small part to a field test this weekend of the two engines by swapping the mufflers.
Here is what I experienced when I switched out the mufflers and tach'd the result.
Magnum .32ARNV with stock muffler saw 14900 consistant and 15000 a couple times
Magnum .32ARNV with the MACS muffler 15900+ just a couple rpm less that 16000 (1000 more rpms)
OS .40LA with stock muffler saw 10900 consistant and 11200 a couple times
OS .40LA with the MACS muffler 11500 consistant and 11700 one or twice (only about a 500 rpm boost)
I may have been overpropped on the .40 but not that much and in both cases all that was done was to switch out the muffler on the engines, all other settings were left alone. I did not adjust the needle nor did I need to on the .32 When I did try to tweek it, there was little to no change in the needle setting. On the .40 I did get a 100 or so more rpm when I tried to tweek it after the initial rpm check.
I was seriously impressed with the rpm boost the MACS muffler produced in that little Magnum.32 It also winds up really quick on the MACS muffler and these are NOT tuned mufflers so run up is consistent....you never hear it "get on the pipe".
As far as the OS .40 even though the results were not as impressive as with the .32 there will be a MACS muffler on my birthday and X-Mas list for the .40 They just sound soo cool. If there is a drawback it is their size, so that would be the trade off.
I am going to get off the soapbox now and post a couple pictures of the LT build.

BTE that is a good looking build there, should do real good off of grass. I could not comment on engine choices as I would have just been talking out of my other end

As I mentioned my goal is to give this build a bush plane look. Most of my time has been spent designing the gear and making it fit in the right location together with the MACS muffler. As you can tell I rotated the engine to put the muffler out the bottom just for the aesthetics, but that required a new firewall for clearance purposes and what will eventually be a small mod in the shape of the nose. I am using the stock mounting bolt locations for the stock gear in case I ever want/need to go back to that gear they will already be there.
The landing gear is impressive. I may need to try something like that some day.

When I get to the wing I am about 98% decided on the combination of leading edge slats and Junkers style ailerons which will be used as flaperons. Brakes I toyed with the idea but the .32 winds up so fast I don't think I'll need them to facilitate a short field takeoff. 
My initial research dug up this graphic which I think will be the basis for the wing.

Alright!! Been away for a few days, celebrating our 45th anniversary, and I come back to see a bush plane in the making - - OUTSTANDING!!!! Y'gotta love those wheels, and the pipe doesn't hurt her either - definitely gonna be a fun bird.
Y'know, I remember the Kadet ultralight in a magazine too. I've only ever gotten Model Aviation and Model Airplane News, so it's pretty much gotta be one of those.

Congratulations! Celebrated my 30th just a few weeks ago, hope I can make it to 45!!
Slow going at the moment, for a couple reasons.
1. The engine and landing gear are requiring some extra engineering to make them work without changing too many of those classic lines.
2. It's 118 degrees in the garage right now!
