_Futaba 10C is the answer for 9C replacement, IMO. I've used it several times.
_There's not much relation between the 9C and the Aurora 9. I have been using it for more than 1 year.
_I agree with you that the Optic 6 is better than the EXAP (I have several of these), but needs to be redesigned --> too ugly.
_Your money, buy what you want as long as you're happy.
_I dont work for Futaba. I am an aero guy and has nothing to do with Futaba.
