Hi all, here is my scratch built, collapsible, T frame tricopter (T-tricopter). I used 2 - 24" towel bars, calculated the distance the rear rotor would need to be in order to make a perfect triangle and cut it to length. Also used some light weight aluminum L bar to lock the arms in place and 1/8" by 5/8" aluminum bar stock to make landing gear. This thing flies like a dream and is very compact when collapsed. Let me know what you think.

Scratch built T-tricopter, i86 board, in The Dark Flight (3 min 35 sec)

the 3rd motor + servo is rudder and holds up the back of the tri

Here is my H copter. I have flown it a few times but still need to do some tinkering. Holds 2 1600mah 3s lipos and a gopro but I only get about 5-6 minutes from it. Has lots of lift so I might put the timing on the esc's to low for more effeciency. I used nylon bolts as Subaru4WD suggested which worked out well since I put her in the ground hard upside down.

There is 1/4 inch lexan over the esc's which provides the rigidity and protection needed for my style of flying. Now I need to protect my precious KK2 board.

Well done guys. Love these T and H quad, simple and works well.

So I made a wooden H at the weekend as an fpv'er, so basic, only had 6mm ply for the sandwich plank so wouldn't mind lightening that up a bit tbh, it does fly ok on a windy test in the back garden so...
Wouldn't mind some more powerful motors though, the 1175s on there are getting warm after a pack with just gentle hovering.




Ronrc,
Is there any difference in flight with the T over a trad tricopter layout? Yours looks great!!

You should mount the KK2 under the plexi like your ESC's are.

This thing flys real nice, so nice in fact that I have been thinking of building one.

I agree. I was pondering that this morning on the way home.

Not sure what you mean. The servo and 3rd motor are connected to a Y cable then plugged into the M3 port on the KK2 board?

The 3rd motor uses M3. The servo uses M4.

roll: the front left motor speeds up = roll right, front right motor speeds up = roll left

pitch: back motor speeds up = pushes tri forward, front two motors speed up = pushes tri back.

yaw: servo changes the angle at which the rear motor gives thrust and there for changes direction of tri. the angle/speed of this motor affects yaw and pitch.

Alright thats what I was wondering. The servo just plugs into the M4 port on the KK2 board like it another motor. Got all the parts ordered to build my first quad but the tri copter really intrigues me. Thanks again.

snipeworm, I'm building an Hcopter similar to yours but with the same mechanism on front and back as my T-tricopter. That way it will collapse to a nice compact size for transport to just about anywhere.
