Here's the mount I made for my BME 105. It sets the motor out about 2" and fills Keith's bill for support around the entire circumference of the radial engine mount. It's seen hundreds of flights and this year will be its third year of duty mostly behind a BME 110. It's light, builds quick, and I can say that I've not experienced any compression of the wood in the motor mount and resulting loosening of the bolts. Many ways to skin a cat, for sure, this has proved absolutely trouble free for me.
