 An engine of 40 h.p. or higher, such as this 48 h.p. 2-cycle engine, has been used to power the G1. (Visit our Engines Page) |
IMPORTANT: Vortech offers the G-1 plans as a curiosity for those interested in homebuilt helicopters because of its intriguing size and simplicity; however, Vortech has no direct experience with either the design or flight of this model and so cannot and does not endorse this as a proven aircraft. While people have reported building and flying this model, it appears that those flying versions were variations or enhancements of the original design. The G-1’s control system is minimal; also, this craft will not autorotate. For those interested in a more practical and proven design, please consider the Choppy or the Aeros (neither of the 2 would cost much more to build than the G-1). More elaborate designs that have been tested and flown are the Skylark and the HRH. In general: Developed, tested and sold in the 1970's by Compcop, the G-1 was meant to fill the need for an affordable, easy-to-build ultralight helicopter. They created this helicopter for home construction with ordinary tools at a low cost. The tiny size would qualify the G-1 as a license-free "Ultralight Aircraft" (see FAR Part 103). The construction manual details the design of the original Compcop G-1 from their original prints. |

THE KESTREL is a single-seat
ultralight helicopter powered by small jet engines
mounted on the tips of the rotorblades. This form of power
eliminates the need for a tail rotor, simplifying and reducing
the cost of construction.
IMPORTANT:
this manual provides an overview of the construction of
the jet helicopter, showing frame construction and many details
regarding the integration of the control system, jets, fuel-flow
system, and rotorsystem. The manual provides a schematic view of
the rotorhead, but does
not
detail the construction of the rotorhead, rotorhub, rotorblades
or jets. The jet-helicopter rotorhead and jets can be built from separate prints
(requires machining).
