A typical winch launch yeilds about 1/3 of the runway/field available, this is a fantastic result, Bill!
Perhaps we should be measuring the launch as a percentage of field length, then there would actually be a record available for everyone to shoot for, regardless of locality.
So...
With a runway of 3100m and a launch of 1718, the current known record is 55.42%


Get out there and break it!!
