I'm having issues With my DX3c & will need a new one .I have a number of SR3000 & SR300 receivers that I'd like to keep. Will they work with one of the newer models, & which ones?

Unfortunately they will not work with newer spektrum radios.

Ads contend the DX5C will work with older receivers. How old they dont say. Anyone know more about this?

just doing lite reading you see what it operates in...

• Compatible with DSMR and DSM2* receivers (DSM2 only operates on 16.5ms frame rate)

those rx are dsm tech 2004 way outdated

Yup. After a little research on my receivers, I figured that was the difference. Gotta upgrade i guess, or look for a deal on an older one. Thanks

FYI - SR215 is $29.99.... I don't know think a high end radio brand sells any receivers lower than that. And its commonly available on line or in hobby shops, shouldn't be hard to find.

I have a DX5c with my SCTe will check and see what receiver is in it the next time I am at the bench.

thanks, guys.
