We used to run Cox Babe Bee or Golden Bee .049 engines on the 'Lil Satan. We'd open the tank and put the fuel pickup to the bottom center of the tank. We'd then mount the engine sideways so that the needle valve and cylinder pointed to the center of the circle. Om flight, centrifugal force kept the fuel from running out, and the pickup was on the extreme outside of the circle.

You could do the same thing with the Black Widow engines that had the integral tank. The Cox tank/mount for the TeeDee .049/.051 could be mounted the same way.
