Default Futaba receiver model numbers?

Need help understanding the numbering system for Futaba receivers... I understand that the last number represents the channels, and that D indicates Dual Conversion, but am confused about the 12X, 13X, 14X designations.. e.g.; what is the difference between R128, R138 and R148 8 channel receivers? Are there any other significant model number issues?

TIA!!

Jim

Well first, I am not an expert.
I can tell you what I know.
R is for receiver.
12?, 13?, 14? are model package types. The electronics inside may be different as well
??7, ??8, ??9 is the number of channels
D as I understand is for dual conversion.
P for PCM and F for PPM

R149DP is a reciever, package type 14, 9 channel, dual conversion, PCM modulation.

Geistware,

Thanks for the reply

I presume the higher the number (12, 13, 14) the later the version?? Any advantages of one model over another?

Any compatibility issues with either a 9AC or 6YG transmitter?

TIA

Jim

This is not necessarily true.
If I remember correctly, the 12 came out with the 512 PCM units.
Following that the 14 were released with a smaller housing and for the 1024 PCM units.
The 13 is new at least for the PCM version (1024) and I have not seen an FM version.
Remember, while each unit comes in a PCM version, only the 12, and 14 come in a FM version. I have at least one of each, and they all work just great.

Now, I am really confused. I have R129DP which is a 1024 unit. What was the number for the 512 unit?

You are correct.
THE 124, 127, 128 DP are all PCM that are 512.
I do stand corrected.

Hi iflyj3,

On Futaba receivers, the first number denotes that it is either a Synthesized (3) receiver, or a crystaled (1) receiver. The second number denotes the model and the third number denotes the number of channels. The D of course means Dual Conversion, the P or F means PCM or FM.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

Sincerely,
Krysta
Lead Futaba Customer Service and Programming Technician
