Ed, those are beautiful! Are they all scratch made? Does your F-22 have a full flying stab? I especially LOVE the Fantom. I'm very interested in obtaining a kit from you.Put me on a waiting list. Please?
Awesome work!
Best regards, Joe

Yep, full flying stab on the F-22 and F-4. The F-4 had some weird tendencies, if/when I repair it I'll have to try to fix some things.

Yes, all scratchbuilt from the ground up.

I got the laser parts months ago but haven't finished fitting them together. Summertime burnout sucks.

Ed just curious. How much was the cost for the laser cutting? For my f16 parts i was asked 160 euro (parts for fuse) , eee about 220 dollars. Deam this is not fair.

My first batch was at a discount but it was about 45 US dollars I think. I think the next cut will be a bit over 50. One tip the guy at AKMmodels gave me (and also from someone who got some parts cut before me) was to not use spline curves on the parts because they are computationally intensive and slow to cut. Use arcs or short straight line segments (I used the straight lines) to describe curves. On curved sections I used a point about every 1/4" or 5mm, depending on how sharp the curve was, the sharper the curve the closer the points.

Ed and Barry,

There is a lisp routine for AutoCAD that will take splines and turn them into joined polylines, makes this a snap.

When I open autocad it's like a monkey staring at a rubics cube...no idea. The whole black screen and white lines thing throws me to start with, and even drawing a line...I never took the time to figure it out. Designcad works for me!

Ed,

Where the heck have I been for the last 1021 days...? Just stumbled on this thread this evening.

Well, now there is a face to attach to the name...

Nice job on the F22.

good to know eric! I know rhino did it with simple click function, but didnt know how in cad. I like rhino but sometimes its actually too simple, when you want to really get in and get acurate it can be tough at times. Sometimes I will build it in cad geometrically so i know its accurate or level or specific thickness's, then i'll shove it to rhino and smooth it around.

Monkey? - Rubix cube? Yeah, I hear you. Retro-grade Ron here. Scissors and heavy paper is my medium of preferance.

Go F-22 Ed, you will be happy!
