Speed in combat might be a necessary evil in AMA RC rule book combat, the way the rules have been developed, but I think the best quality combat, by far is SLOW RC combat. MY son and I average over 1200 combat minutes every summer [each], along with a couple hundred more minutes worth of streamer chasing with friends, and we usually can make it through a season on 3 planes each. We fly nothing but .15 and under combat at 50 mph or less. More combat time, less time building and repairing. Leave the high speed jousting matches for the rich guys with lots of time and money to burn, I've done it, it is thrilling, but isn't any more fun than the slow stuff.
