RE: 2,4 Ghz and float planes
I've been using CorrisonX on all my Spektrum/JR 2.4 receivers as soon as they come thru the door. I have about twenty flying at the moment and no issues at all. I just dunk them and let them drip dry.
Works for me. I totally immersed one several years on a SeawindEp and it survived.
