V2 Motor mount with landing gear. Now without the lexan sheet. Mounts to 13mm wood booms. Inspired by and made for the Batbone air frame from flitetest.com. Fits NTM type motors but can modded for others.
Landing gear component compatible with my tricopter tail pivot (v1 and v2) and the batbone from flitetest.com (with center cross-brace removed)

If your making a tricopter see my tail pivot motor mount. http://www.thingiverse.com/thing:350802

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.

This is the motor I have been using. http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=17345
