Another thought: fuel tank location - presuming you'll use a separate tank engine, align the tank relative to the direction of flight... ...NOT to the engine thrust line.

I don't know if an integral tank will feed well, if at all, when mounted behind a shaft turned about 35° out from the direction of flight. (estimated Leading Edge sweepback angle.)

For a separate tank, long accepted guidance is: fuel pickup tube at or near the same height as the jet in the spraybar. If it is a sprinkler, TeeDee type inlet, aim for about the middle of the opening. Simple spraybar (as on Medallions) makes the jet easier to find.

No idea about the integral backplate tanks. If the tank can be adjusted, you can test run to see how it goes. Remember the integral tank's fuel pickup is on the rear surface, and aiming the engine's shaft 'outward' will puddle quite a bit of fuel forward, away from the pickup tube.

Luck and good results!
