Micro tricopter

After being unable to find a small tricopter (yet lots of small quads) I set out to make one. I designed this around the KK2 control board and Turnigy 1811 2900kv motors.

17cm between motor shafts and 29cm from each propeller tip.
170g with 1000Mah battery
11-12min flight time.
Assembled with zip ties so it is easy to replace parts. I have not yet needed to as it holds up quite well.
Soldering is required.

Changes:
6-6-14: Re-uploaded "micro tri arm4". Minor change to zip tie slots for the motor mount, mostly cosmetic.
6-10-14: Update both servo mounts to reduce confusion about what hole to use and to make is easier to feed the zip tie though.
6-14-14: Update tail motor side for minor cosmetic error for the ziptie slot. Also added extra ziptie slot landing gear/lights/esc and such.
6-14-14: added a reinforced version of the center body, if your trying to minimize weight or do not crash much
