Flying a plank in the worst weather aound doesnt bother me .. I have been flying here in the rain and wind forever .Thats half the fun with them . But I am relativly new to winter rain flying with helis and I have only been flying them when it isnt raining and with planks I dont care if it is raining ..I just keep thinking the bearings and the gyro will get all screwed up in the rain .. I just keep thinking there should be a way to keep the gyro dry.. Besides the gyro is just about the most expensive part of the heli ..
