My concept for a "Swappable" J3 Cub "Trainer"

[NewZee]

Hi All,
Well I was inspired by my recent sucess building and maidening my FT Spitfire, so I thought a high wing trainer would be better for me to learn on, I really wasn't keen on the Old Fogey so I came up with this concept for a J3 Cub! It has a 40" wingspan and a 24" length. It will accept the standard power pod. I am using the same construction principles I learned on the Spitfire. Let me know what you think.

I think it looks awesome! Any idea what the all up weight is going to be?

I'm getting real close to finding out! I'll be sure to let you know I'm guessing around 600-650g with landing gear

Should be a real floater with all that wing up there, but exactly what you want in a cub.

NewZee,
This is incredible! Now I want one. I always loved the Cub. Are those plans I see? (hint hint). Did you use SketchUp to design? Nice job!

I didn't use SketchUp, I printed out a picture of a cub plan and scaled up the dimensions off the picture by 4.5 to 1 to get the ballpark dimensions I wanted. I drew it out on a sheet of posterboard and cut it out for my template, had to tweak a few things here and thee to make sure the power pod fit see the first picture to see the power pod location, here is the picture started with, the wing has a 7" cord.

That's impressive. I don't know if I have the skill to do something like that, but I sure will try.

The only thing its missing is yellow paint. Fantastic job!

Man that looks great. Try to learn SketchUp and make plans for it! Might even be cool to get it to the FT guys and you might be able to sell the plans for a small royalty on each kit sold.

Did the minwax today will get the yellow paint on her over the next day or two, and post a few pics then.

I'll need to download sketchup and play around! I'm not even 100% sure this will fly yet?

I would love to see plans for that!!! It looks amazing!

It's a cub! it will fly.

Yeah that's what I fiqure!!! I was pretty true to the plan so I'm sure it will go up.... it's the comming down I'm having trouble with:black_eyed:

 

[xuzme720]

It will come down too, no problem. The issue might be with how quick it comes down!

Awesome Job!! love it

 

[NewZee]

Awesome Job!! love it

Thanks! I'm working on struts now, since it's a high wing and constructed like the Spitfire wing I don't want to fold it up, so I'm fashioning some wing struts just like the real cubs. I'm using barbeque scewers, and for the "eyelets" to connect to the wing and fuslage I'm trying small ellectrical crimp on connectors that I will glue on I'm hopeful they will take the tension load? I'll post some pics when I get it fiqured out.

I appreciate all the encouragement from all of you! If it turns out good and flys well, I'll do my best to get plans posted so you all can make your own ( from what I see from all your posts you are all talented enough not to need my help).

pics of the Cub in paint!

Hi all,
Well the "Cub" is a liitle closer to done with the addition of the classic Yellow (and I do mean YELLOW) paint scheme! how do you like it?
