Hello,

I just wondered what the difference is between the following receivers besides the price:

Futaba PCM 148DP Rx 8Ch

and

Futaba PCM 138DP Dual Conversion 8ch Rx

Is it the size of the receivers that differ?

Which would you guys recommend?

Thanks.

Hi,

As far as I can tell its basically the same receiver (same chip, dual conversion, bla bla bla). Its the same size and shape as the 127df, probably the same case with a different label.

Futaba needed a justifiably cheaper receiver to release with the 6x pcm radios, 138dp seems to be their answer. I have 4 of the 138's so far, have'nt noticed any differences. Not sure if the output frame rate or resolution is the same but they feel the same in the air as my 148dp's and 149dp's.

Definitely cheaper
