Tri - V tail multi rotor XBS

Based on my printable tri copter X bow http://www.thingiverse.com/thing:227974
I had a few requests for a simple boom version and wanted to upgrade my X525 quad to a V-tail
This is based on the X 525 booms that are 12.7 mm square booms so should fit stock US 1/2 inch wood booms as well
Can be configured as a Tri or V tail copter
Designed around the KK 2.0 control board
Update March 15> Added a standard "flat" motor base for 10mm booms and and adapted version of my pivot mechanism also for 10mm booms. The other parts for the pivot can be found at the Xbow tri copter ( link above)
Update 17 Feb> Added some 10mm versions of spacers and rear motor mounts to suit 10mm square booms.
For people wanting folding front arms i've added a V2 base plate with a simple latch system
Update > added some 40deg motor mounts for the V tail
