Longer lines make all the difference in the world. With 26 footers you are spinning like a top. Even at 100 mph you don't turn half as fast on 60 or 70 foot lines. I flew C/L combat through out the 60's as well as B Speed and rat race. Never had a problem with dizziness. Even today I still fly C/L occasionally. The long line big planes are great. The little short line jobs are horrible. Still have a bunch of my old Johnson and Super Tigre C/L engines.
