What are the max and minimum cockpit weights?
The min-max range is 70kg to 110kg (154lbs to 243lbs). The max cockpit weight can be increased easily to 130kg or 287lbs (without the self-launch installation). Extreme pilot weights can be accommodated by special weight & balance of the glider. The JS1 has dual tail ballast tanks and a brass tailwheel is available in place of the VesconiteTM tailwheel.
