Midairs still happen if you use streamers, but streamers as a target cut down on damage to equipment. I like my combat time to building and repair time to be greater than one to one, and I don't think many can boast that. My son and I have logged over 8 hours of actual combat time in the last 2 weeks and we are only on our second pair of planes. We are flying PAW .15 powered foamies with 40-50 feet of streamer.
