Mounted the engine today. Seems like it was a long time coming. Everything went together good. You can see in the picture I added straps on the engine mount. On the Falconar F-12 plans the addition of the straps raised the engine mount from 7 G's to 9's. I didn't work the math out on adding the straps to my mount, but it cuts down the column length and increases the strength of the tubes in compression. Feels like I just crested the top of a hill and can finally see home on the far mountain.
