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

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.

Spot on. Dick Fano was a great influence on the hobby for decades. He is missed since his passing. We also have guys like Miles Reed, who always encourage newcomers and make the hobby fun for those in all the nearby clubs as well, with their knowledge, skills, and wonderful story telling. In the past, we had no less than three hobby stores in this little town. We are down to one, Aerotech (Dicks place), but it is one of the best I have ever seen, and I traveled the country for ten years. Prices compare to mail order (many times less), and even special order items are usually less expensive than you can buy on your own and are quickly ordered. With some 5 clubs in a 25 mile radius, that have been around for decades, plenty of experience is always available. Yes, this is a fine area to be involved in the hobby.

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.


Two Great Ideas
