This is an adaptation of HALLSTUDIO's American Made Sphere It should hold together well with small black rubberbands (hair products). I haven't added mounting brackets yet.

This is a fantasy foam fighter fuselage scaled up from Jarel's original open source design. I will post both his design and my scaled up version.

I need something to help me with orientation. I want something I can eventually adapt to an FPV camera. I want to mount the camera in the cockpit with a little bit of nose showing in the camera view. I have found a couple designs that I could probably adapt but then the other day, I found Jarel's post for his really nifty design. http://www.rcgroups.com/forums/showthread.php?t=1595253

Here is what I have so far. This is my first attempt at working with foam. I love it. Specially since I took the advice of a few other people and got the foam core board from Dollar Tree. "Everything is a Dollar" 20x30inch foam core board for $1.00. Cant beat it. Soak it in alcohol for about a min and the paper comes right off. It is 5mm thick but since I scaled it up by about 250% over the original pattern it worked out well.

Jarel's original is scaled for a MQX which is a small quad copter. My tricopter is quite a bit bigger the arm size is 10 inches center to motor, and the center frame is about 6 inches in diameter. I don't know that the actual scale turned out to be but it is roughly 250% bigger.

As I have stated, this is my first go using foam as a medium. I am learning as I go. I really like it and I will most definitely be using it again. I have the model mostly finished in roughing it out. Now I have to learn how to...Continue Reading

Here is my latest Tricopter. (my only) I generally cannibalize my previous version to make my newest. This one I went with the whole tail rotating. Like the Scarab Tri, but my design was way first. (several months ago) It is a really stable way of running the yaw. The only weight on the tail now is the motor, just like the other two struts. Basically it is two Traxxas 18mm X 12mm X 4mm bearings inside of two clamping blocks. The boom slides inside the bearings. There is a fiberglass ring with set screw on the inside and outside to keep the tail boom from sliding out. I used 3/8th inch (10mm) thick G10 to make my boom arm clamps and the motor mount clamps. I like using the 10mm on the boom clamps it worked out pretty well. For the motor mount clamps I will be changing to these, or even home made aluminum "U" bolts.

The motor mounts are cut from 1/8th inch G10 (3.175mm)

The frame is G10 1/16th inch (roughly 1.6mm) Strong and light weight.

The booms are the super cheapo carbon fiber from HK. Pretty but not that strong. I'm going to try these Fiberglass ones from GLB.

Okay... The super cheapo carbon fiber 450 booms on HK are TOO easy to break. First crash snapped one right at the frame mounts. The GLB fiberglass booms splintered down the length. So now I'm trying to find a better, thicker woven carbon or fiberglass 12mm boom.

For the landing gear I used two sets of these from HK with some green foam balls glued on the ends. They are really strong and...Continue Reading

Here is my new project...

I stumbled across signguy's Build a Tricopter Thread. I immediately fell in love with the simplicity, stability and inexpensive price tag. I knew right away this would be my next project. Money is still tight but I can scratch together some money here and there and get this baby flying. Here is a Sketchup rendering of my frame. I actually have a lot of it built. I'm still waiting on some parts to finish the really long shipping from China.
