how long are these lasting?. The MR200 & MR3000 RX's. Reason why i ask is that i have three MR200's and two MR3000's they all work with my DX3c and (DX4S which i have to send into service) or i'll need to purchase the DX5Pro or 6R. i hope my DX3c stays alive, it's so easy to use.
it seems the RX's are discontinued.
Maybe that Darin Jordan kid would know?
