Ehhh its been off and on designing and re designing. I recently got modelcad which I'm going to start using once I get an outline I'm happy with. I have pretty much settled on going electric for a few reasons. The biggest one is having an uncut cowl. I could not find an engine that would not require some decent surgery. Also going electric will allow for some thermal flights and a smoother camera platform. But over all I'm not closer that I was before lol. I still think about the project often and ways to design and build it. Oh yeah there's no way I'm making a mold. It's going to be all built up. Hows yours?

lol.... Well just got back on the build. Been doing other things and swamped myself with "crap"... But on the electric, I feel ya. Had been working on other alternative propulsion systems and platforms, including a parendev magnet motor; compressed air2 stroke nitro system, but niether would come clean on the secretes!!!!! Any way, going the "free-energy" route. Electric motor-solar cells-wind generator...... I want to fly a while, and not have any juice probs.. Still going the molded route though.. I see the first prototype going all wrong! I always plan for the worst.. So molding will afford me to quickly make strong duplicates quickly. How ever, I think I need to make this sucker well under 20lbs( 20lbs was with 50cc gaser). Use only kevlar/carbon resen, and in thin resis layers. like just enough resin to get the "wet out".
I have model cad, but hate it. so good luck with that. Oh, yea.. I have a friend in new york in colege for engineering that is making a autonomous supercomputer for the plane and this sucker should have enough room iside for all that gear, and the camera's etc... So I hope I can generate enough juice for the electricity needed. um... yup. thats it I guess. The invite is still open should you choose.. good luck

The best way to contact a member with a request that is this specific is to use the Private Message option. It also avoids listing your email address to the world and ending up with a mountain of SPAM.

ORIGINAL: John Mason

I have always had a fascination for the predator uavs so i started designing a model of one.
What I have done so far:
I decided on a 1/8th scale of the original
66':99" wingspan
36.2': 54.3" fuse length
Weight not really sure hopefully under 8lbs
I started with the fuselage and designed the fuse formers first. I havent gotten to the dome on the front yet.
I am open to suggestions on an airfoil for the wing right now im pretty stuck on the clark y due the fact that this is my first project of this nature.
I have a question about the wing and how I should go about designing it, rib spacing, spars and the uniqe sweeping of the leading and trailing edges.

Heres a picture of what I have so far. please let me know if im making any fatal mistakes, im open to suggestions from anyone.
Can I get a copy CAD plans?

Would make a great project.
The original thread starter suggested 1/8th scale. Much to small IMO.
1/5th scale at least...
Remember it's all wing.

Regarding wing construction, sniff around the glider forum. They're making models with far larger spans than that.
1/3rd scale is quite normal here in Europe. Multi section wings, no problems.
