Difference between R309DPS & R319DPS
 

What, besides 21 grams in weight is the difference between the older Futaba R309DPS receiver and the newer Futaba R319DPS receiver ?? Are the specs the same for selectivity, etc. ??
Thanks....Ed M.

OK, electrically what is the difference?

I long for the days where the manufactorers gave REAL Tech specs on their equipment.
I guess I'm not going to get an answer to my question concerning the R309DPS and R319DPS.
Bax, I read the commercially available size and weight specs on the 2 receivers so I knew that information already and you should have realized that by my question ( 21 grams difference ).
If you can answer my original question concerning selectivity, sensitivity, image rejection, etc. I'd be glad to see it. I've been a Futaba user for sport and competition for 16 years.
