All of the control line speed events are round the pole. I have been thinking maybe they should be flown from outside the circle since no one can run fast enough to keep up with them anymore. RC would work, but would be hard to fit inside the little planes, and the vibration would hurt them. There is a 'Revolution System' for flying outside the circle with a .35 and smaller size motor. I would like to see a video of it. The little micro foamies would work with some tipweight and noseweight in a gym much like the above video. I put some pics of my Cox control line leckie as it is somewhat related. It isn't able to loop. The Flyline one seems much better. It could maybe be improved with two batteries, but would likely burn out something.
