Crab
Never flown a 902 but a lot on a 520, the biggest thing is the slow response of the anti torque system. Once you are used to it not a problem but does give a problem when there is an unexpected gust ! Well that was my opinion compared to a tail rotor. In some respects it is comparable to a fenestron on a 341 in a strong wind doing spot turns if you want a comparison you would understand. Before everyone shoots me down here I know the comparison is not hugely accurate but it is to give a feel for Crab as he would have more than a few hours on a 341
