Engine mount for GMS .76
 

Can anyone tell me what mount I should use? Mounting it on a H9 Hellcat. I'd ideally want something with vibration reduction built in. I was looking at the
Dubro Motor Mount .75-1.08 2-Stroke. Would that work?

Thanks

BTW what towwer recommends is the Great Planes Adjustable Engine Mount .60-1.20.

If you want a vibration reduction mount, Dubro has several.

I think the choice will depend on how long the mount needs to be to locate the prop drive the right distance from the firewall.

Yeah thats why I was asking, was wondering if anyone had already done this setup. The H9 manual says that from the front of the drive washer to the firewall it needs to be 142mm / 5 9/16". Thats why I was thinking the Dubro Motor Mount .75-1.08.

Unless someone with experience speaks up, I'd probably go with this one:

The beams are 3.25 inches long and the total length is 4 inches.
If the beams are longer than you need you can always cut them off.
It's harder to make them longer.
