Vortech G-1

TerryLeave a comment

The G-1 Ultrtalight Helicopter, created in the early 1970s by Art Weilage, was tested and sold as low-cost kits by Compcop, Inc. Vortech offers the original construction prints to hobbyists curious about this design, or who want to study the concept as inspiration for a design of their own.

Developed, tested and sold in the 1970’s by Compcop, the G-1 was designed to fill the need for an affordable, easy-to-build ultralight helicopter. The entire helicopter can be built at home with ordinary tools at a low cost. No license is required to fly the G-1 because it is in the license-free “Ultralight Aircraft” category (see FAR Part 103). The construction manual provides all the details needed to build the G-1 with an engine of 40 h.p. or higher. The three McCulloch go-cart engines can be replaced with a single engine such as the Rotax 447. Aluminium construction.

Carries one person. Takes off and lands vertically. Flies forward, backward, sideward, & hovers.

von Hagan 1911 Aeroplane

TerryLeave a comment

Built by German immigrant Alexander von Hagan in Seattle, Washington, the machine had two sets of silk wings, an aluminium framework, two motors and three propellers. It weighed 600 pounds without the operator. One propeller was in the front, the second three-quarters back, and the third at the rear. One 40 hp motor ran the two front propellers and a smaller one of 35 hp powered the rear. Von Hagan was born in 1859 and served in the German army for 14 years.

von Cosel 1930 monoplane

TerryLeave a comment

In 1930 Carl T von Cosel, of Key West FL. Built a two-place cabin, high-wing monoplane amphibian, registered N879Y and powered by a 180hp LeRhône rotary engine.

The wings were never attached, so the plane was never flown. Some reports claimed that von Cosel, an undertaker by trade, kept his dead wife in it for an unstated period of time.

When he left Key West in 1940, he took the plane with him and both disappeared.

Volmer VJ-21 Jaybird

TerryLeave a comment

The Jarvis Jaybird design was acquired by Volmer Jensen as homebuilt project soon after World War II and became the VJ-21 Jaybird with retractable wheels and 75hp Continental A75 engine.

The 1947 Volmer Jaybird all-metal evolution features a pod nacelle with a pusher engine and has monowheel gear with outriggers on the wings. Reportedly more than 900 plans sold to builders through the 1960s.

A later owner (ca.1960) put a 125hp Continental C125 in, repositioned wings slightly lower and added small auxiliary fins.
