Printed Tricopter
Description
I'm still working out some problems with the current design.
It might have to do mostly with my terrible piloting skills, but the current Tricopter center plate get ripped in pieces much too easy. I never had that much problems with my Quadrocopter design ( thingiverse.com/thing:4812 ), which seems to be much sturdier.
Of course, the Tricopter design is foldable, which means that the construction is a bit more complex. Also the Tricopter has a much larger diameter and is heavier than the Quadro, which might also cause problems with my (very) rough landings :-/

but they probably work also with other motors.
Use 10x10mm aluminum or wood profiles for the arms. I used 40cm long arms and 10" props.
The servo is a BMS-385DMAX Digital Servo

I first used KKMulticopter controller electronics for the Tricopter (also visible on the photos below). Meanwhile, I switched to a MultiWii controller. Both work great, but the MultiWii controller also supports an accelerator chip (auto leveling), barometer and magnetometer...
See the pictures in the following image gallery for more details on the assembly

You'll need a 624 ball bearing a M4 x 20 mm bolt, some M4 washers, a M4 nut, 2 M3 bolts, washers and nylock nuts for the servo assembly.

This frame may work well with these Y6 motor mounts that I am working on http://www.thingiverse.com/thi...
This is a nice collapsable center frame for a tricopter. I am planning on building
å small y6 with this center piece. But in the list of files I don't seem to be able to find the 3rd part of the centerpiece thåt goes under the t matching shaped pieces with a little standoff legs.
You picture these 3 parts together here:

Now where is the file for the 3rd smaller part that goes on the bottom of the two parts that fir together to hold the collapsable legs?
I'd much appreciate the file. Or am I blind and just missing it?
Thanks

Nice work! I just placed an order for a quad project I want to work on.
I got 10x10mm hollow carbon rods, some of the new Donkey motors, and 15amp esc's.
Today I brought the Gaui 330x out of the hanger for the first time these season!
I've been looking at the kk board, but they are out of stock except on ebay. Where did you pick up the MWC board? I haven't made u
p my mind yet on what to use.
I did my own PCB for the MWC and eventually burned out the WiiMotion+, Nunchuck and BMP085 barometer, due to a minor design flaw :-[
Now I'm flying with a "Paris board", my nephew gave me and a brand new FreeFlight IMU, containing a gyro, acc, barometer and magnetometer...
Looking good! What's the advantage of a tricopter over a quadcopter? Does trading a motor/propellor unit for a servo result in longer flight times?
The advantage is one motor and one esc less then the quadro.
The disadvantages:
Because of the bearing clearance, ist less precise to flie.
In case of an crash, there is more damage.
Less payload.
I prefer the quradro-, hexa-, octo- version.
Less moveing parts, higher payload and less moveing parts.
I use the PCC at my multicopters it work's great.

Finally got around to assembling this.
It is quite a bit smaller than yours, the arms are about 9" to center, which makes it a bit fiddly. But the printed parts are working great.
Thank you
