Back McCandless M4

McCandless M4

The McCandless M4 was a British single-seater ultra-light autogyro first flown in 1961. The original McCandless M4 was powered by a Triumph motor-cycle engine, this was later briefly replaced by a Norton motor-cycle engine which was abandoned in favour of a Volkswagen flat-four four-cylinder horizontally-opposed air-cooled engine which could be connected to the propeller without gears. The McCandless M4 had a cruising speed of 130km/h.

A Triumph engined helicopter device? Back in the 70's, I came across a bungalow between Chepstow and Caldicot which had scrap Volvos and other vehicles in the rough ground of the property. There to my astonishment was an abandoned helicopter /autogiro-? with an iron top end pre unit 650 engine. time passed and I was unable to find the location again. Could it have been one of the Mc Candless creations? I often muse on whether it survived.

Does anyone have any information on G-ARWW? My late father built this in our garage & flew it a lot back in the 70s - so perhaps sold it to you Brendan?

I bought a 54 inch Avro Avis propeller around 1958 in Belfast.
I often wonder if Rex McCandlass used it at sometime.
Would anyone have any info.

The developers of the McCandless were Rex and Cromie McCandless. McCandless is also the developer of the Featherbed motorcycleframe, first powered with again a Triumph engine, then adopted by Norton for it's excellent behavior for racing and road machines. The McCandlesses also developed the Mule, a Norton-engine driven small all terrain car, and a racertype as well. There are still two (proto)types, one M1 and one M4 at the Ulster Folk and Transport Museum, and probably one flying VW engine-driven M4 type having registrationnumber EI-ASR. In total there were 8 built.

Do you have any comments ?
