Yep. Flew in light to moderate rain on two occasions. It was a 60 size cub on floats so the plane was already fairly water resistant. Generally the covering will protect the wood so your radio, lightning, and comfort are the main concern. I fly 2.4 and did not have any difficulty with range and the three other guys flying didn't either. It's true that 2.4 does not penetrate vary far into water but light to moderate rain is not that dense IMHO. Someone mentioned their wood prop coming apart. Water will do this so any float flyer should have plastic or composite prop anyhow.
