thanks for the link and 50c temperature rating was for transmitter not receiver (rechecked manual)

That sounds more like it.  When I was initially investigating the Futaba heat issues, I remember reading that both Spektrum and Airtronics were somewhere in the 70 to 71 Celsius limit for receivers.

happy to report that there has been a crash reported while using a ATX, now i know the system works

Visited one of our LHSes today, and they showed me the new stock of the older model R617FS Futaba FASST receivers.  All had the white dots near the antenna.

So these must be the higher heat tolerance ones.

increasing range of 2.4ghz

Thanks for posting the link.

But range has really never been the issue with 2.4GHz.systems.

wow that's 4 times more power 

another technical aspect is 2.4 ghz length of  antenna required will be less than a 72mhz, u can see it.


2.4 ghz will have more range than 72mhz 

shorter antennas like in 2.4ghz are cool that donot render our movement.

and AM systems will have more higher antena length
less range
