A rather mild baby bee will pull a 'bean just fine. I flew mine on a single bypass baby bee growing up. There isn't much more mild. Even on this weak engine, with 35 ft lines, it will do any stunt you ask as long as the engine is running healthy.
On a mild bee, a 6x3 prop will preform better than a 5x3 prop, unless a rubber ducky, then a 6x4 as it will flatten and loose pitch. The larger diameter will provide more thrust, at a loss of RPM vs the smaller size. On a mild baby bee the rpm loss is not that much as the engine won't spool up to the higher RPM that a more performance setup will provide.
