Given my experiences so far... strengthened by today's test... I fully accept Doubletap's observation that 2.4GHz range can be diminished by humidity. No doubt, the effects will vary with specific Tx and Rx combinations and different spread-spectrum technologies(?)... but from now on, no more flying on post-rain days with my stock FMS ET800 radio gear.
My DSM2 compatible Rx has arrived... and I hope to install it this weekend. Then I wait for another post-rainy day so I can do test 2. I'm curious to see if it is affected as well.
Well there you go!
There is nothing better than empirical data to corroborate and validate a theory.
BTW, there is no reason to give up flying on a muggy day, just keep in mind the reduced reception range and keep the ship tight, that's all.
