RACE 66

Hello All:
Thought I would post here as it would apply best. I've scanned the forum's but no luck. I am looking for "metal" style engine mounts. I know there are many variables out there. Specifically, the style like the "old school" CB mount brand. For 40,60,90 size 2 and 4 stroke engines. All cast aluminum came in short or long length beams. Looking around now it is all fibre/plastic renforced type. I know there are "sheet" metal types out there, but still looking for the "cast" type. Any suggestions? Thanks

There tends to be a problem with the aluminum mounts. They are heavy. They stress crack and break. They won't hold a screw without using Locktite or a jam nut.

The plastic mounts will hold without vibrating out a sheetmetal screw

You can drill and tap plastic mounts with machine screw threads and they will hold the screw without it vibrating out even without lock nuts

You may want to check out the Edson mounts.

I've got a couple and I'm real happy with them.

They also sell the Tatone aluminum mounts.

I use both Aluminum and Plastic...

I us the fiber glass mounts all the time with no problem vibrateing loose. I use self tapping screws into a pilot hole.

You could try "Just Engines" in the UK they make cast alloy engine mounts.

I'm using metal mounts on two of my airplanes right now. never had a problem with breakage or screws coming out. OS and saito make mounts for their engines with pre-drilled and tapped holes. Tatone made metal mounts and they are still around as do J'tec. The weight difference between a metal mount and a plastic/ fiberglass mount is negligible. If your plane can't handle the weight you need a bigger engine. A lot bigger.

I bought a H9 Ultra Stick and put a Saito 56 on it. They come with a nice aluminum motor mount that clamps the engine so you can change engines without redrilling. that part works well but I had to glue a piece of 5/16" square steel key stock 6" long on the horizontal stabilizer to balance the plane.

I removed the engine mount and replaced it with a Great Planes plastic mount, pried off the piece of key stock and went flying. The battery is against F-2 and everything else is in its normal place. that is how much more a metal mount weighs

Thanks to all who responded. Yes I am aware there has been problems with "cracking, heaviness etc. of the aluminum mounts. Personally I've flow this stye of mount for many years and have NEVER had problems of those listed. Not saying that won't happen, it just hasn't happend to me. Have used the metal type from .20 size to .91 size two stroke through the years.
Thanks to "Broken Wings" as suggesting M.E.C.O.A. as they continue distributing the C.B. mounts. It is difficult to "find" old school products nowdays, they tend to be "hidden" away from mainstream advertising. Again Thanks for all the responses.
