We were using 4,000' of rope and we're getting 1,500' - 1,700' launches. Our field elevation is 5,022'. We weren't trying for the highest possible since we were doing launch training. Once we replace the drum this winter we will be able to use up to 8,500' of rope. Will be quite a fun ride up to high alts even a tow plane will be envious of.
