JR R770S PCM Receiver.

[mike mueller]

 I'm like you I fly the 649 in F3a and the 770 in Flat foamies and sport. I've never had a problem with either but I'd like to see the 770's a little more before sticking it in a 2 meter. Mike

945 is larger/heavier (1.6 oz) to accomodate the added electronics of dual
conversion - I think the 955 is the same weight as it shares the case of the
945.

The 9 channel 649 (PCM) and 549 (FM) are 1 oz and older in design than the
new 770 (PCM) - I think the newer design of the 770 and the smaller
footprint area for the plugs (2 less channels) account for the lighter
weight (.7 oz). As Doug, I've flown the 770 in electrics and it is solid.
I've flown the 700 (the FM version of the 770) pretty extensively in 12 lb
Ultrastick with 6 digital servos and it was solid.

I personally fly the 649 in the pattern stuff - but I doubt you'd have
problems with any of the above receivers.

In a nut shell, would you trust a ZN or PL plane to the R770S?
