Sorry to hear about your crash. I myself am having my first issues with my 2.4 system. Just lost my second airplane within 1 week at 2 seperate flying fields. The ar 6100 and 500. I have 3 Expensive edf's I am terrified to fly now. I sent the Transmitter back to Spektrum to Check the RF unit. Also look into the new UPGRADE of the RF unit to DSMX technology. It is available this April and will cost $75 and 1 week of down time. It will still work on the older DSM2 RX's and newer DSMX ones as well. I think they are finally addressing the issues at hand.
BTW a great 3D Foamy is a Juka from DW Foamies.
