Eagle R & D Mission Statement
& D will design and produce a new generation Rotary Wing Aircraft
which will provide more utility at less cost than any previous helicopter.
Our goal in essence, is to create a single place quality equivalent of
the Robinson R-22 for 1/5 the price. Good hardware is not enough. We are
totally committed to do everything in our power to guarantee the success
and safety of our builders and pilots, we will provide complete customer
service from video and personal instruction right through to on-site check
out and flight testing.

Speed & Altitude )
The HELICYCLE in it's normal configuration
is designed to cruise along side the industry standard R-22. Landings
and take offs at above 9000 ft. are possible because of a 7.5/1 power
to weight ratio. The same as the Hughes 500.
FLIGHT STABILITY: (
Wind & Gust )
Aircraft stability is always challenged by adverse
weather conditions. It is normally assumed that lighter aircraft will be
further affected. The HELICYCLE at one half the weight of the R-22
is capable of being operated in the same weather conditions as the R-22,
with no appreciable increase in pilot work load over that of the R-22.
The HELICYCLE has numerous design features
which improve it's handling qualities. These include:
EASE OF OPERATION :
( Leaning to fly )
A fully harmonized rotor.
A modulated collective system.
Very low 2-per-rev vibration level due to elastomeric thrust bearings.
Generous flapping angle for low "G" and slope landing conditions.
Control friction devices.
Electronic throttle control.
The cyclic control in the HELICYCLE accurately
models the feel of the R-22. With a high degree of control power, it provides
a natural transition for the R-22 qualified student pilot. Low 2-per-rev
vibration gives it a solid feel which is confidence inspiring during the
transition. The modulated collective, automatic RPM control and R-22 equivalent
foot pedal feel and response also help reduce that sweaty palm feeling
on the first lift off. Preparing for autorotations is facilitated by practicing
confidence inspiring throttle chops and quick stops which clearly show
the lift and energy available in this rotor with the power off.
COST OF OPERATION :
(In cost per air mile)
Direct operating costs:
Indirect operating costs:
|Routine maintenance at 100 hour intervals
|Engine maintenance at 250 hour intervals
|Airframe retirement time parts reserve fund
||0.37 per mile
LOW ROUTINE MAINTENANCE: (100
1 air mile = 1 1/2 road miles on average. It's easy to see
that the per mile cost of the HELICYCLE is less than that of a pick-up
truck. This cost estimate assumes a new engine every 750 hours
and a 1500
hour complete airframe overhaul. This schedule keeps the ship in constant
new condition. A 45 minute commute is equivalent on average to a
15-17 minute flight considering no traffic and no stop lights for the helicopter.
This is a time savings of over two days per month!
It is well known that the R-22 needs very
little mechanical attention at 100 hour intervals. This is largely operation
with the HELICYCLE and 30+ years of helicopter design experience,
we feel confident that the HELICYCLE components will stand up equally
as well. There are some differences. The R-22 utilizes mostly sealed bearings,
so little greasing is necessary. To aid in controlling costs, the HELICYCLE
compromises in this area with a 50/50 approach. There are 12 grease zerks
and 2 sliders that do need a minute or two of attention now then, the rest
of the bearings are sealed.
When your goal is commercial aircraft
quality, you must use aerospace grade materials. This dramatically increases
machining complexity and fabrication difficulty. Gearbox components, rotor
hub pitch spindles, blade spars and other parts suddenly get very costly
if you can't make them yourself, & no one can afford to buy them if
they have commercial helicopter price tags. The tough problem of producing
commercial quality parts in low volume for an affordable price is the heart
and soul of the Eagle R & D helicopter program. We believe the HELICYCLE
will make the grade into certified level lifetimes for it's drive train
and rotor system components. (1500-2000 hrs.).
We didn't intend to be the one flying the
HELICYCLE when it ran into high voltage wires at 110 mph. We were
thankful to our Guardian Angel and also to the crash worthy design features
of the ship when we walked away unhurt afterwards. The safety feature designed
into the HELICYCLE are too numerous to mention here. The video which
shows the aftermath of this crash puts them into a far more believable
A system of checks and balances built right
into the design of the components and assemblies which prevents the
builder from making any serious tolerance & construction errors.
Cheerful technical phone assistance.
