Well, you can invert the cylinder and you can invert the needle valve.  The
Black Widow I had didn't have a clunk inside the tank.

Interesting solutions and I already used then for another canard pusher
I never flew, but the point of the Astro Blaster is to have a .049
attached to a dummy rocket engine so you can fly either rocket boost
or .049 depending on how much money you've got.  For that, you'd pretty
much need a tank mounted engine and tank mounted engines can't handle
both inverted flight and a pusher configuration.
