RE: Futaba 3PM-2.4G, do I need a failsafe?
I have the 3PM 2.4Ghz like yours on order. I haven't been able to find a manual for it except the 3PM FM. I've been trying to understand the HRS/Failsafe requirements myself. I'd rather not have to use a 6V power pack to get HRS & saved Failsafe because of the extra cost, weight, and maintenance. Did your radio come with a manual specific to the 3PM 2.4Ghz radio? At least there's the manual failsafe you mentioned.
BTW, how do you like the radio and what range are you getting in the neighbourhood street area?
