I find it difficult to believe that the Futaba 2.4 Rx is constructed significantly different from other Rx produced by Futaba. Sure it operates on a different frequency and uses the Fasst system but it would be built using existing technologies and methods that are common to other frequency Rxs. Has any one tried exposing to excessive heat other frequency Rx and or Rx from different manufactures? It is very possible you will discover the same failures due to the same cause, excessive heat.

I suspect people are fearful of new R/C system. How many supposed 'shoot downs' from the past were actually equipment failure caused by excessive heat or what ever?? Who knows.
