Summary of Contents for Kinkade Slow Hawk 2
- Page 1 Congratulations on your purchase of the Kinkade Slow Hawk 2 electric R/C ornithopter. The Slow Hawk 2 is a new and unique electric powered R/C "park flyer" based upon the ornithopter principle, that is, the model obtains its lift and thrust from flapping wings like a real bird. The...
- Page 2 Slow Hawk 2 also utilizes an articulated bird-like tail for positive control which functions as both rudder and elevator. Years of research and development went into the design, resulting in a simple and efficient model with excellent flight performance designed for the seasoned hobbyist or newcomer to the realm of R/C micro-flight.
- Page 3 Wind speed: 0 to 8 mph Flying area required: roughly 50 X 50 yds. Designer: Sean Kinkade Manual written by: Sean Kinkade ___________________________________________________________________________________ 2) Required for operation : 1) 3 channel radio, 2 sub-micro servos, and a sub-micro receiver. 2) A 2 cell 1000-1500 Mah 7.4 volt li-poly battery pack.
- Page 4 Check all parts. If you find any missing or defective parts, contact your local HobbyTechnik dealer or HobbyTechnik. Your Slow Hawk 2 box should contain the following items: 1) One fuselage plate with assembled gearbox, motor, connecting rods. 2) One main parts bag.
- Page 5 5) Radio Selection and Preparation The only criteria required for selecting a radio is that the receiver be of the micro variety, the radio have a minimum of three channels, and the two servos be of the sub-micro variety. An example of micro receivers currently available are the Hitec Feather receiver, the MPI MX 6800 Pico universal FM receiver, the GWS R4-P micro receiver.
- Page 6 Wingsail is not warranted against burns! The Slow Hawk 2 is designed to use either JST connectors or the 2 pin polarized Deans connector (Deans part no. 1001, available at hobby shops) to connect the battery pack to the speed control.
- Page 7 control is "on" and un-plugging it is "off". Some speed controllers, such as GWS ICS 300 eight amp ESC and the 10-amp Electrifly C-10, come pre-wired with two main JST type connectors. If you intend to use the JST connectors for your model and have one of these controllers, then it is only required that you solder a mating connector to your battery unless your battery also came with a JST connector.
- Page 8 Refer to the receivers manufacturers instructions for proper polarity, but rule of thumb is: negative lead on wires ( black or brown wire) always faces against the circuit board of the receiver when the lead is plugged in to the receiver. This applies to speed control and all servos as well.
- Page 9 When using the HS-56 servo you will be using the cross shaped plastic servo horn that comes with the servo, eliminating the need of the previously supplied G-10 part. It is used by itself to achieve the same 4 point O-ring tail mount so the supplied cross shaped G-10 part is not required when using the HS-56 servo.
- Page 10 Use the longer, heavy duty double ended stock servo arm that comes with the HS-55 (or the cross shaped horn on the new HS-56 servo.) Use these heavy duty arms only as any other arms are too fragile. Mount the pushrod screw to the OUTER hole ( farthest from center) for maximum pushrod travel or the middle hole for less travel but more holding power.
- Page 11 2) Ball bearing wing hinge assembly: The hinge bearing plates are installed on the fuselage with the bearings already installed in them. The wing spars are attached simply by slipping them between bearing plates on each side and screwing in the supplied #5-40 X 3/4" socket head cap screws. Screw the cap screws in from the front of the bird and apply BLUE Loctite to screw at the center hole at the end of the aluminum spar ferrule and screw the bolt in and out slightly to disperse the Loc-tite.

Once you have your model fully assembled with the radio gear installed and the battery charged you are ready to fly. The Slow Hawk 2 is park flyer, and at low throttle setting a slow flyer, however weather-wise it should be treated like a conventional slow flyer. Completely calm conditions are optimum for the the best flight performance. - Page 13 The Slow Hawk 2 comes with a standard provision for gliding flight. This simple yet effective "glide lock" device, invented by Sean Kinkade, allows the wings of the bird to lock in at an optimum dihedral for both thermal glides and for safe glide-in landings. There are actually two glide modes and the model will go into one mode or the other automatically when the power is shut off by throttling down.
- Page 14 1) Initially, gain adequate altitude to before attempting to throttle down to a glide. Once you have a feel for it and are adept at throttle control and its effect on flight, then glides can be attempted at lower altitudes. 2) It's recommended that you recover from a "pigeon glide"...
- Page 15 The membrane wing on Kinkade ornithopters is more like a hybird of a bird wing and an insect wing, since it has an unjointed main spar. One FAQ heard by us over the years is "how can the ornithopter fly when the wing pushes up just much air as it pushes down since it has no joint to spill the air like a live bird".
- Page 16 are the recommended corrective actions which are listed sequentially. Naturally the minimal amount of adjustments to correct the problem should be made, so the steps should be followed in the order listed with test flights after each step until the trim issue is resolved. Trimming the wing: Step 1) Flip Wingsail: If you find your Slow Hawk has a turning tendency that cannot be comfortably corrected by the...
- Page 17 Treat it with the same respect you would a loaded weapon. Kinkade ornithopters are not meant to be used to control nuisance birds at airports, golf courses, landfill sites, or vineyards, nor used in conjunction with any other type of wildlife control.
