Bensen B-19

Towed by car, the B-19 becomes airborne at about 23 mph. Flight is completely pilot-controlled, limited only by the length of the tow cable. By adding a cable release, once airborne the pilot may free the craft for unrestricted soaring.

The B-19 may easily be converted at any time to the powered B-20, as is fully detailed in the same Construction Plans.
