Reducing Cowl vibration
#27
I have used rubber grommets similar to the ones that come with servos. But the ideal way is to build a cowl ring that is held in place with pegs and two screws on the bottom.

Another way to minimize cowl mount problems is to move the cowl mounts and fasteners as far forward as possible.
Get as far as you can from the aft edge of the cowl.
I have had great success using long 90 degree nylon control horns on the firewall with my mount screws going into the body of the horn where you would normally hook up your control linkage.

North Canton Ohio is a great model airplane area with a great hobby shop with a heritage that goes back a few years

Sorry to go off topic for a few syllables, but I am passionate about this hobby and the heritage this area has in it, having enjoyed some 4 decades of RC myself.
On topic, advice from guys around here usually comes from having tried or seen it all at one time or another.

I just went to the Dubro website and they have a new cowl mount on the first page that you might be interested in.

Since I adhere to the idea that "simple is good", and I'm cheap, my solution for many years is to use CA hinge material as a backing. After the initial hole has been made, I use about 1/2 of a CA hinge to cover the hole and CA it in place. Let it completely set, then redrill the cowl hole through the CA hinge. This stuff id remarkably tough and resilient. It gives good results on fiberglass or plastic cowls.
