Im planning on using this in the RCM 1.20 Cloud dancer. I know that you can get a rear mounting plate to stand off mount the engine (http://www.seaplanesupply.com/aluminum.htm). i was planning on doing the U-can-do 3D but found the cloud dancer a little more appealing (i have flown the .40 size so i think stepping up to a 96" may be a new alternative).
