Interesting stuff regarding the AR500 RX I lost a very nice model, a magnattila at a club fly in a few weeks ago , I contacted horizon hobbies and was asked to send TX and RX back to them, they told me they had done a soak test on the Rx for two days and could not find any fault but had updated the software in the Tx output and that they would exchange the AR500 rx for a AF6200 on this occasion but did not say if they found a fault, this was the second AF500 I had sent back to them on that occasion they just sent a replacment AF500 with no explanation, It woulld have been nice to know what was the fault,
I am unsure as to how reliable Spektrum is as lots of comments in our exeter club more so from the 2.4 futaba user's , Roy
