like a R/C thing , profile,
Tank inboard and level with engine.

Any problems with this set up ?

It can work very well. You can set the engine for max power for takeoff, and then it'll richen up a bit for level flight, leaving you with some reserve for maneuvers. It should not be set up with "ram air". That can lead to too much richening in level flight. If you're using a uniflow tank, be sure the uniflow is in some neutral area, like near the backplate of the engine.
