I'll be shortly heading out to a part of the world that is rainy at this time of the year. I don't plan to fly the P4 in rain or in conditions where it looks like rain is imminent. However, should there be a sudden shower, I want to have a sense of P4's tolerance to drizzle. Any experiences here? (If it should get caught up in rain I, of course, will immediately abort the flight and bring it home.)
