Thanks a bunch for the compliments ya'll!

I did all the design work for it in CAD, so I do have CAD plans. They are almost 'done', just need a little more detailing on one of the sheets (2 sheet plans) for someone else to be able to build from them. (I draw plans for myself, build the plane and then go back and label/detail/make changes to them if I need to....). The other benefit of doing the work in CAD was that I was able to have a 'short kit' CNC cut for it, which I used to build this prototype. Finally, I took pictures of almost every construction step in high res digital so that I could do instructions if needed (and I do mean every step, I took over 100 pictures...).

I would like to make the short kits and plans/instructions available, but I want to make sure it is 'right on' before I do so. I don't want something out in the world with my name on it that is not right.

I mounted the engine using metal 'sub' mounts. The engine bolts to the mounts, then the mounts are bolted to the maple engine rails. Makes the mount extremely strong, and engine changes can be done in a snap. I could take this on from a TT .46 Pro to a .63 4stroker in a pretty short time because of the rail/submount system. Other advantage is that it makes setting the right thrust easy to experiment with and set.

Here's some pics of the mounts and the bones.....
