Craft air upstart std sailplane launch kit. New and sealed. Rubber may be aged but still feels soft inside bag. some of my RC models items are vintage. I do my best to describe and show them as they are but all are sold as-is. Sealed items are also sold as-is. Designed for lanching 2 meter and small (hand launch) sailplanes, in limited space. Produces launches of over 200' and requires only 300' of field.
