Well...perhaps, but the only reason I chimed in on this one is because (horror of horrors) I have a near-antique GP Cub that has been flying for 13yrs with the fuel tank a full inch above the carb centerline. I simply installed a small tank. What the heck...with the OS .70, it takes off at 1/3 throttle, and cruises at a fast idle. With an 8oz tank, you can fly until you need a shave, land, and still have half a tank. Never had a problem. In other types of models...tank position is more of an issue.

IMO...ARF mfrs would do well to engineer their products correctly.
