There were numerous complaints about the weak firewall in H9 ARF's in the past three or four years, but H9 didn't seem to listen or care.
Seems they don't need to make any improvements to continue to sell the models. Everytime they announce a new one, and the problems from the previous models are brought up, the reply from the H-9 "loyal" is "They are ARFs, and you are expected to do a little "fix-up".
What incentive do they have to improve them, they sell all they can import.
