I call BS on range problems in the rain on 2.4-Been to several fly-in's -hard rain still flyin 2.4. Not just me-everyone that was flying from 1/3rd scale to trainers-Never had one glitch. There was never a lack of radio reception from any radio -We were all flying at the Jim Rice event four or five years ago and it was a hard rain most of the day and we all kept flying without any issues-if rain causes range problems I have never seen it-but I have heard several guys state that 2.4 will not work in the rain and that is nonsense!!!!
