If you are trying to hover at below 3 feet, the down-wash from the blades will defect off the floor, and cause the AXE to get very squirrily and seem un-controllable. Having the training-gear can also cause the heli to get the "wiggles-while-hovering."
As far as a "sim" I wouldn't know, don't have one, don't want one, I prefer the "REAL" flying/crashing experience!
