Snapshot
of Hoyt hovering from the hover practice video
More hover practice May 14, 2006
The outside air temperature was 100oF ( 38 C. ). The engine ran quite
cool and there was plenty of power.
I weigh 175 lb ( 80 Kg ), with a 12 lb ( 5.4 Kg bar on the back and a 4
lb (1.8 Kg) weight on the front toe. )

A slide
presentation I gave twice in 1986
to American Helicopter Society meetings in the Phoenix,
Arizona US area regarding
my torqueless electric air pressure jet tip propelled
helicopter ideas and an advanced high speed
helicopter using the moments from an offset flapping hub and
shaft torque to unload the retreating blade.

Chronicle
of building the Mosquito kit -- start to finish (about an hour of video)
Work in progress as of November 16, 2005.
The tail rotor and main rotor are installed.
The tail rotor is complete and adjusted.
The main rotor is ready for lead-lag adjustment, balancing,
and tracking.
Progress as of Nov. 16, 2005
Trailer and blade support solutions.
Work in progress as of April 15, 2006.
I constructed a highly customized trailer for the open cockpit Mosquito
based on a Harbor Freight Tools foldable trailer Model 90154 (about
US$300), Model 41005 trailer jack,
Model 92860 winch, 4x8' 3/4 Inch plywood, lots of 3/8 bolts and others,
3/4" jack screw rod,8 foot
2x6's and 2x4's and iron angle bracket material. Here are some
pictures:
The blade is supported by 4" id ABS pipe with cutouts. Note a small
aluminum member bolted to the hub
for the front ABS pipe's fore-aft constraint. It is mounted on the
bottom on top of the front toe pad.
The rear ABS pipe merely clips to the tail boom. The blade rotation is
constrained with a steel reinforced
2x4 wood block above the
small drive sprocket, as shown below.

A jack screw I added to tilt the trailer, mainly to allow clearance of
the tail rotor
to the truck.

Work in progress as of August7, 2005.
See the removable PVC pipe stick clip to hold the cyclic centered.
I added the fuel pump, as I had problems with air bubbles in the fuel
filter.
I added a battery voltmeter to check if it needs charging.
I added a bicycle brake lever to open the "chokes", which are really
opening for more fuel
to flow to the engine. They don't actually restrict the intake airflow.

My custom designed ABS portable wheels (4.5 pounds for both);
aluminum "glove box" ( 4.5 pounds );
and frame to carry two 2 1/2 gallon "Jerry cans" (4.5 pounds) are
emphasized
here.
This entire assembly just clips to the airframe, there is no
modification
whatsoever
to the Mosquito airframe.
