No, and in fact my guess is that it would be particularly bad when combined with a standoff-style mounting system. When you think about the forces on the standoffs, it seems there would be a tremendous amount of stress on the engine mounting tabs and on the engine mounting bolts.

The [link=http://www.rcuniverse.com/forum/m_6285026/anchors_6285026/mpage_1/key_/anchor/tm.htm#6285026]Hyde-style soft isolator mount[/link] is the best (only?) way to go, and they aren't all that hard to make once you undertand the process and [link=http://www.rcuniverse.com/forum/fb.asp?m=9692415]how the concept works[/link].

I was a bit dubious at first about how well the mount would work and about my ability to make one, but it turned out to be easier than I thought, and it is working fabulously well. I will be making another one in the next few months if I am able to find a second-hand plane to go with my #2 SAP-180.
