Designed by Ingenieur [Engineer] Paul Haves, and built by Automobilwerk Lauer in Halle a.d. Saale, Germany, in 1910. This was a 3-seater machine, 12m long, the main wing area was 24 sq.m. with various stabilizing surfaces, canard, etc., providing a further 15 sq.m. Weight with the pilot and two passengers was 500kg.
The HZ-5 is the last design of a series of self-built helicopters by Ing. Havertz. The prototype did fly 56 hours during flight tests circa 1966. The project was discontinued due to the age of Mr. Havertz.
A development of an earlier Nelson powered motor glider, the Buzzer 2’s propeller is driven through a 2:1 reduction chain, running enclosed in oil, which brings propeller rpm down to 3,000. Designed by Walter Haufe for self launching, it features a single centerline fixed wheel and small wing outrigger wheels for taxiing, with a steel tube fuselage and tail, single-spar, single-strut wood wing, and fabric cover.

Designed and built by Walter Haufe, of Neenah, Wisconsin, this single-seater high wing motor glider is powered by a 40hp Nelson H-59 four-cylinder horizontally-opposed engine mounted in the nose. The engine, when stopped for soaring flight, swings back through 80° inside its cowling so that the two-blade fixed-pitch propeller, also designed and built by Mr Haufe, is stopped in the vertical position and lies flat along the top of the cowling to minimise drag. The cooling air intakes for the cylinders are open when the engine is running but are closed when the engine is stopped. The cantilever wooden wing is of semi-elliptical planform with upturned tips, the fuselage is a fabric covered steel tube structure and the tail unit is wooden with fabric covering. Landing gear consists of a fixed monowheel and a tailskid, plus an unusual skid with small balancer wheel just behind the engine cowling to prevent the prop from touching the ground. The pilot sits under a removable cockpit canopy set into the wing leading edge. The Hawk prototype, N1051Z, made its first flight in 1962.

Ultralight
Towards the end of March 1910 the townsfolk of Wolverhampton had a chance to see a flying machine at close quarters when the Hartill mono-plane was displayed in the furniture showrooms of Robert H. Davies in Darlington Street. It drew a great deal of interest and its designer Mr Hartill, was on hand to explain all about it.
He explained to the enthralled gathering of onlookers that before starting work on the project he went over to the Rheims Flying Meeting, the worlds first, and to the Paris Aero Show of 1909. Where he made close examination of the machines present.
His machine was designed and constructed by Mr A.E.Hartill. a plumbing and gas engineer with premises at the top end of Cleveland Street, on the corner of Snow Hill, (as noted by his 1910 advert).
It was made to the order of a Doctor Hands, who is noted in Kelly’s 1905 directory as Surgeon and Medical Officer of Health.to the Wednesfield District Council and also medical officer and public vaccinator for for Wolverhampton Union Cottage Homes 138 Wednesfield Road.
On his return to Wolverhampton Mr Hartill began construction of the mono-plane for Doctor Hands and though it was the good doctor who was to foot the bills, the machine was to be known by the name of its designer and was to be flown by him or is son on its trials.
When completed the Hartill flying machine was seen to be very similar in layout to the Demoiselle, of very light construction, with pilot seated close to the ground under the wing and motor. The Wolverhampton machine was however considerably larger, having a wing span of 26ft against the Demoiselle’s 18. there was also differences in the control system, for whilst wing warping was used ( a common idea of the period), the Hartill was known for having fluted wings with tips that could be drawn up, supposedly to improve stability when landing or in difficult wind conditions.
However, since since the machine did not fly, it is not possible to say if the idea would have worked .
Construction was of steel and bamboo, wing covering was rubberized aero fabric, an Alveston horizontally opposed twin cylinder engine of 20h.p. was fitted and all weight was around 4cwt.
As would be expected, both Wolverhampton flying machines, the Hartill and the Star were entered for the Dunstall Flying Week held over the period June 27- July 2nd 1910, as this meeting was devised to encourage British Aviation.
One of the numerous bothers that beset the Hartill mono-plane was late delivery of the Alveston motor and a suitable airscrew.
The Doctor Hands/Hartill team tried manfully to get airborne and suffered a few frights, the mono-plane nosing over a couple of times when taxiing. It is not known what happened to this flying machine, but it seems certain it was destined not to fly.
The 1910 Hartman monoplane was designed and built by Arthur Hartman (22 years old) in the USA.
