Picture of Inexpensive Wooden Tri-copter!
Build an inexpensive multi-rotor Tri-Copter using wood, zip ties, and 8 screws!

I am using this tri-copter to test servo controllers. There were a few challenges to getting this off the ground and hopefully this helps others with a really cool project, enjoy!  

This is a spin off of another one of my projects currently on Kickstarter, check it out also if you get a chance: or search for Blue-Rx.

Total: less than $200.00

Step 2: Create the Frame

Picture of Create the Frame
Build the frame using 1/2 or 5/8 inch square wood sock.  A strong light weight wood is best, but this beast will have enough power to lift  almost any frame!  The arms are 12 inches long and roughly in a 120 deg pattern. The two arms opposite the servo are the front pair, they are slightly closer to each other then that of the tail, this was purely for aesthetics.  The arms are glued and screwed down to the base plate which is a 1/4 inch masonite.

It is best to get the angles accurate between the arms but believe it or not, its not really necessary.  If they are close the computer control via the multi-rotor control board will compensate for any error!

I purchased three 1000 KV motors and 30A ESC's. I am a beginner at RC stuff so I don't really know much. My question is: for my three motors, what battery should I get?

3300 mAh Lipo would work

wt is the use of AVR programmer.

It seems like everybody wants to see a vid of the beast flying. And I think this is not because it is not flying, but how is this thing flying? :) Don't get me wrong, but these days I was building my first tricopter (RCExplorer type - easy to build indeed) and it was not like in the movies :( Indeed building the thing is pretty easy, but make it fly is quite complicated. So I think a nice instructable is the one entitled "Build a easy to setup for flight tricopter" :) Cheers!
you said its inexpensive and its 200$!
that's good for a tricopter

Flashing the control board with Tri-Copter firmware is different in your example than what the real software shows. It's close but not he same for identical hardware. The board selection is slightly different as well as the input file. I see the 1.6 version and the 2.9 version which are different than your screen shots. Which way to go?

The performance is incredibly fast. How does it perform with a camera payload?

I fail to see where the AVR Board was used or the Arduino AVR
Hi, tell me please where i can find a remote control like yours?

How long can it fly for
what size servo did you use for your tail?
That looks both awesome and extremely dangerous. The way it loops around in the video makes me think it has a taste for blood.
Excellent job. I especially like that there is a parts list with links and prices! Even if I don't do THIS project, I will come back to check where you got your parts.
