HI Gus,
Yep...I've flown in light rain with out any issues...but only on our older frequencies. I flew on Ch. 38...now I'm flying 2.4 gig radio's.

I have flown in freezing rain up in Homer, Alaska and that was a trip. No issues with the radio, but my biplane ended up with several pounds of ice on the wings and that almost cost me the model. The prop, wing and tail feathers picked up a bit of ice and I needed almost full power to get her down. I landed ok, but that was the last flight of the day.

Soft Landings Always,
Bobby of Maui
