Thnx everyone!
@ Funflyaddict - Thanks!

Nice! Another Burrito! What colorscheme are you going to use?
@ srg123cohen - Nope, I've used a couple of templates to cut and grind my ribs into shape. I have the principle on photo from my Diamant project. I wish I had access to a Laser cutter, or CNC-mill. Maybe I'm going to build one some other time. You've got small kits with 2/4-step electrical engines. A little DIY and a Dremel and you've got a simple CNC.
Some examples:

Today I did add a extra landing gear to my Burrito. It's just for fun and not permanent. This is so ugly! But it would be fun, landing upside down.
