Just kidding. It's worth the time to do it right.

Status: offline 		If things goes well and can stay in my house where I have nice workshop, then I beleive prototype will fly before summer... if I have to move, then it will delay my plans...

next weeks I will update the post with wings, rudders and stab finished...got one issue with rudders and stabs at post curing (temp too high and not progressive enough so I have few bubbles on gelcoat which I have to repair to get a clean surface. Except that little deffects (corrected on next parts) the edges are perfectly strait (which confirms that my halves molds done by CNC are right! and the shape is exactly symmetric as expected.

Status: offline 		here are the pics of the result of my last progress...

I did 2 rudders (small issue with post curing making bubbles on gelcoat...had send then), one stab, and 2 temporary wings just to see how they fit with airframe (they are made of polyester resin and the finish is...not good but not so important for now).

also finished the mold for fuel tanks. nice one!

no more progress expected in coming weeks as I will be very busy...

enjoy...

Status: offline 		Firstly your work is truly awesome and I am amazed at your progress.

I am new relativilty new to this composite mouding stuff and have a question for you.
Why do you CNC out the positives? Wouldn't it be better to CNC the negative into moulding material. The reason I am asking is because I am just about to do that for my own project.

Status: offline 		I am doing the positive because it is for me easier to see some impefections of my modeling and also, for certain sharp edges if it was negatve mold , due to tool diameter, I would not get the result I want.

last but not least, the material milled is wood so then it is molded as a negative made of resin.
if it was aluminium then it could be ok

Proper finishing is difficult if you begin with a negative as well.

after lots of delay (ssssoooo busy with lots of other stuffs), here is a nozzle which I will use to make a mold.
I am also working on some other parts...pics will come later.

I also ajusted and fixed the rudders on the airframe (they are removable).

Status: offline 		wow. ive been experimenting with generative shape design making a f-22 as well. and must say its a lot more difficult than it seemed from videos ive seen and ur project but it looks worth it.
