I stumbled on to this thread as I am just in the early thought processes of scratch building a twin this winter...more on that later. A great collection of mounts, Chellie, and inspired others to chime in..., Enter moi.
I work mostly around boats, repair, inspection etc so most of my engineering and thinking wraps around the materials we use and see on a regular basis. alot of hitech materials used in rc flying we see in ultra light boat construction. found this in a local marine wholesalers show room and had to try it. Its Coosa board, high density foam re-enforced with two layers of glass near each surface. Density is the same as balsa (average) at 15 lbs/cu.ft. Machines well, can be drilled and tapped for machine screws 4-40 etc and plan on screwing motor cowl into sides ahead of firewall. Structurally it replaces plywood in boat construction so its STRONG. This mount is for my 3 lb 109. and only had 1/2" on my shelf. Would have used 1/4" and drilled smaller lightning holes. In its bench configuration I stood on it and it didn't even wimper..tried to take a picture of that but ...you get the picture LOL.
