Anyway, I have too much sweat invested in the aircraft not to be exceedingly particular. Too particular, probably.

As a result of the extra weight, more wind was required for successful foot-launching of the Vector 1. As a result, Hall modified the prototype so that it could be auto towed for initial test flights. The test flights exposed the center of gravity issues and showed that with the extra weight the

Vector 1's 150 lb (68 kg) weight came in 25 lb (11 kg) over the weight target that Hall initially hoped for. The root cause for the overweight condition was in the design criteria, especially numbers three and four. The high limit load led to more structural weight. In the

Is there any future for Vector I? As a foot-launcher, I doubt it. At least I don’t plan to foot launch her. Bones too brittle. As to my permitting someone else to fly her, I’m afraid my requirements for sailplane experience would find few candidates. Most of the pilots whom I would trust would

Vector 1 simply flew too fast for safe foot launching. Hall constructed a canopy to try to smooth airflow over the wing center section and thus reduce the stall speed to bring the Vector 1 back down to foot-launching speeds but eventually he lost interest in the project and never flew it again.

The aircraft achieves its light weight through small dimensions, with a wingspan of only 34 ft (10.4 m). The Vector 1 was designed to be foot-launched, with the pilot sitting on a
