Default Jr Reciever, Futaba Radio

Any one know if they are compatable.. I need a 10 channel reciever for my 14MZ but dont want to use the 14 channel they sell as they are very expensive.

Best regards,
Randy

Not so fast. PCM receivers are proprietary, and only work within the same brand as the compatible radio. Does JR make a 10-channel PPM receiver? That's what you would need.

Yep shift select (its available in the programming for a 14mz btw) wont help you with pcm receivers.

Hi Randy,

Please double check my post, shift select for the 14MZ is only for FM/PPM

At the moment only the 14MZ has "shift select" which will allow the use of JR FM/PPM and other Postive shift receivers.

We hope to have an update for the 12Z soon that will allow this also.


Thanks, Krysta

I'm not sure if you can use two on/off channels or not, but it's my understanding that both the 9Z tx's and the R149DP rx's are capable of 10 channel operation. Now I know you said that you're running a 14MHz so the tx stuff won't apply but IIRC, the 9Z has that tenth channel function available on switch "D" and the rx must be sent to Futaba for the mod which utilizes the DSC port for that 10th channel...

The best you are going to do with JR is 9ch. The R549X is the most channels they have in an PPM receiver. The 10ch receivers are PCM and they won't work with the 14MZ

Randy,
How about running two 9ch PCM Futaba receivers. This will save the extra channels normally used for dual elevators etc for other uses. You could have eleven usable channels. It may be cheaper too.

Randy,
You have two receivers running independently. In cases such a elevator where you normally use two channels for two servos, you only use one channel on each receiver freeing a channel. In this case it would be CH 8 freed. You could do the same with ailerons, but you would lose flperon function. You can still get differenial. You just picked up two channels(6 and 8), giving you eleven effective channels. You also get redundancy. It also helps spread the power load on the bus with two rx batteries. You also can have two servos on each of those extra channels and with two locations each. WOW!
