Hi Felix, There can be some problems by flying in the rain.............so it is not exactly an "are you kidding?"type response. As the other gentleman said, make SURE your transmitter is covered. MAKE SURE there is no lightning in the area before you step out in the open with that lightning rod in your hands. I would fly in a light drizzle but that is about it. I saw a young man have RX problems after a flight in fairly heavy "drizzle". He got the plane down, but his LT-25 does not have a good seal
above the windshield at the wing. Moisture got in and got his RX wet, he could not fly again that day because of problems. So, YES you can....... but follow some common sense restrictions.......lownslo......

PS..... as an edited footnote....... At the Internet Fly In last year, the weather was good for the main show Sat and most of Sun. But late Fri afternoon it was a constant rain.....light to medium. (I'm sure some will remember [] ) Anyway..... there were some VERY big and expensive planes being flown in that rain. I was amazed !!!
