Version two of the tail pivot system with built in landing gear for a Tricopter. Mounts to a 13mm wood boom.
Made for and Inspired by the Batbone from Flitetest.com.
No longer needs lexan plastic sheet to bolt the motors to.

For the front motor mounts see http://www.thingiverse.com/thing:351200

Let me know if you have any suggestions or have a specific motor you want this to be modded for.

IMPORTANT:
If your motors run too hot the PLA could melt causing a failure, for the first few flights monitor the temperature of the motors. I have about 20+ flights with the extra weight of FPV gear and have had no issues.

PLA, 200 micron 10-35% fill.
Fit for the boom is a little loose to allow for booms that are not exactly 13mm, wood can be wrapped with tape to get a snug fit.

Made for "NTM Prop Drive Series 28-26A 1200kv / 250w" motor from hobbyking but can be modded for others, let me know if you have a specific motor you want to fit.

Other then electronics you will need:
~10 Zip ties
2mm "music wire" used as a pivot shaft.
1mm "music wire" for servo connection.
