Eagle R & D Mission Statement

Eagle R & 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.

PERFORMANCE:( 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.

HANDLING QUALITIES

The HELICYCLE  has numerous design features which improve it's handling qualities. These include:

  1. A fully harmonized rotor.
  2. A modulated collective system.
  3. Very low 2-per-rev vibration level due to elastomeric thrust bearings.  
  4. Generous flapping angle for low "G" and slope landing conditions.
  5. Control friction devices.
  6. Electronic throttle control.
EASE OF OPERATION : ( Leaning to fly )  

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:

Fuel 0.11

 

Indirect operating costs:

Routine maintenance at 100 hour intervals 0.03
Engine maintenance at 250 hour intervals 0.03
Engine replacement  0.11
Airframe retirement time parts reserve fund 0.09
total 0.37 per mile

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!

LOW ROUTINE MAINTENANCE: (100 hour intervals)

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.

COMPONENT LONGEVITY: (major overhaul)

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.).

SAFETY: (crash survivability)

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 perspective.

CUSTOMER SERVICE:

  1. 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.

  2. Cheerful technical phone assistance.

  3. 10 hours of videos covering every builder construction detail.

  4. Control and rotor system theory and rigging instructions.

  5. Final construction and flight check out a builders location or at the factory.
