Dan, you inspired me to pull my planes out yesterday. I'm just learning how to do speed limit combat. So far, I can keep the plane out of the ground and stay out of line tangles. I've had a few midairs though. Yesterday, my son who was flying a Demon with a MK3 and myself flying a Flite Streak with the same setup had ourselves a fast combat match. Both planes flying on bladder flat out. I was able to follow him a bit and it was truly a first for me and a great time. Ken
