I'm looking into to kitting it. I doubt I would produce plans since so few people really build anymore.

The videos are great!
Is there a photograph somewhere so I can marvel at the design?

tri-rotor!

Ok, so I got my tri-rotor going with 3 motors and 1 tilting motor/rudder control. I was wondering if it would be more stable if the motors were farther apart? Right now they are about a 20" circle diameter to motor shafts...

I have the GWS gyros on the motors and will try the new Futaba 401 gyro today...

I will post a picture soon...

You have to compromise between stability and performance. The larger you make the frame, the greater the moment of inertia will be about all axes. The increase in moment arm from the c/g to each motor only goes up linearly, whereas the moment of inertia will go up as the square of the distance. So as you increase the dimensions, you get a more stable but less responsive aircraft. Remember, the gyros are there to provide stability and they can be adjusted to suit your taste. A larger frame usually means more weight too....

Good job, I had almost the same idea.... http://www.rcgroups.com/forums/showthread.php?t=446084 mine will have a tail rotor like a heli. Glad you have your working, now I know where to come if I have problems! Is your CG under the rotors quite a bit or do you think that is not so critical? I'm guessing mine will be around 4oz RTF or less for my large version, hope to get 1.5oz or less for my small one!

Woah, this is awesome. Looks like an elite X-UFO. :P I wonder what it would cost, if it came to the stage of commercially available kit. Ive seen it happen to the hydrofoam, and it might aswell happen to this marvel of modernday RC technology. Patent it while its hot! Someone might steal the idea (also happened to the hydrofoam..).

man, I'd love to see a kit of this thing.. I love the idea... You could hover it around your living room, if you choose..

What all does it involve? I would guess some CF rods with some light ply somewhere in there..

How serious are you about kitting it?

Then better fork out the big bucks. This thing is loaded with expencive electronics.

But I sure like the looks of it. Perhaps you could go see some toy factory, and see if they can cobble together a nice RTF "toy" with an all in one electronics board, and cheap factory made motors and such, like somany micro helicopters out there. It ll just be a little more expencive then the rest, but with a "gadget" flare like that you can affort to. If its around 200 bucks, id be sure to get one!

It's not that bad. What are you comparing it to? I have less in mine than most people have in a Trex. To start off with, you need three motors and ESCs. You could use three cd-rom motors with three of the Thunderbird9s. You need three of the cheap yaw rate gyros for the speed controllers. You could also use one for the yaw gyro, but you won't get the level of performance I had in mind. I use a gy240 for yaw control. When I designed it, I wasn't exactly thinking of selling it at "Toys 'R Us", I had performance in mind...
