About this 3D model

I have decided to get into RC flying using a Tricopter. So I found "Flitetest" on YouTube and they have a diagram for all the parts. So I created the parts in Blender. They also have a scratch build video for the Tricopter and here is the link:- http://flitetest.com/articles/tricopter-scratch-build. I thought others here would like the parts too so here they are. PS I have just added the Wheel arms you will need one of each for it to work. Because one of the arms has been modified to run smoothly between the other. I have included the KK2 top and bottom pieces. They came from here:- http://www.thingiverse.com/thing:124122 So now you have all the parts for the build in one place;). All the pieces with holes have been modified so the holes are now 4mm. Enough room for the M3 bolts and ties.
