Very nice Miloh! I'm not familiar with Sig's Citabria Kit, but I can tell you that some of Sig's kits are older and use 70's style building techniques (like their 1/4 scale cub)

But check out some of their newer kits, or some of the Great Planes kits (my personal favorite). The newer engineering and instructions are fantastic! The planes practically fall together.

Good luck on your new project!

And BTW, that's a great looking assistant!
