Default Series 190 Production Engine Backplate ???



I think the attached picture is of a Series 190 Production .049 Engine which uses a C clip read retainer. How is this type of backplate mounted on an airplane? There are only four screw holes for mounting it to a crank case. I acquired this along with a bunch of other COX parts in a Bay auction for cheap. What I want to do with it is experiment with different reeds and venturi drillings.

maybe the screws that go through the engine also go through the firewall on the plane one othe theory of mine is that it could be from a model car and the engine may have been "lashed" to the chassis with wire.

Those little tabs on the side fit into slots on the plastic model the engine came out of.

Skaliwag is right. It's often referred to as a postage stamp backplate.

The Cox 190 was made for the only flying wing plastic kit that Cox ever made. It was called the spook and it had 190 sq in of wing area and was really innovative for the late 60's. Didn't last long because it was fragile, but it was fast enough to be fun. It set the design parameters I guess for all of the other tankless Cox engines that followed

And once upon a time Goldberg made an adapter so it could be mounted to a firewall. I see the occasionally in the bay.

I have seen a two piece sheet metal mount that was screwed between the screws and the mount. Works quite well if you can bend the metal.
