havent done much in the 22, but alot of fiming in the 44 and i find the 44 to fly sidways best around 15 - 30 knots. any less and it gets twitchy with tail rotor votex one way and main rotor interferance on the tail rotor the other way (i think this is why) and any faster and it starts to tip over (too much drag i think). so as long as you keep an eye on how much cyclic your using to hold it steady (sidways speed) i cant see how mast bumping can happen
