  • Page 20 Step 33 CCPM Radio Review & Setup The next section covers setting the pushrods and servos that will control the helicopter. It is important at this time that you review the instructions provided with your radio that controls the ccpm mixing for the 3 cyclic servos. Reviewing the radio instructions will assist you in becoming familiar with the functions that affect the individual servos and affect the interaction of the three servos working together to control the swashplate.
  • Page 21 Step 35 Pushrod Setup and Adjustments Robinison 22HP Manual Make up all the control pushrods according to the specified lengths shown in the table. Please note that the dimensions listed are from center to center of the ball ends (this has changed from earlier manuals). Depending on the servo brand, the servo horn offers different patterns for fine tuning.
  • Page 22 Step 36 Rotorhead Pushrod Attachment After completing the pushrods, attach the pushrods to the rotor head without the cabin or shroud installed on the helicopter mechanics. At this point the helicopter should be setup, ready to fly, except for the tail rotor and throttle linkages before the fiberglass cabin and tail boom are installed.
  • Page 23 Servo Setup & Adjustments Robinison 22HP Manual Over the next few pages the pushrod hardware will be mounted to the servos horns and ultimately the pushrods them- selves. Each step is well described but lets take a few moments to cover a few basic points on setting up individual servos.
  • Page 24 Step 37 CCPM Swashplate Linkage Three servos are mounted on the front and rear servo brackets. They work together to tilt the swashplate producing the collective pitch, roll cyclic pitch (aileron control) and the fore-aft cyclic pitch (elevator control). The servo horns pro- vided in the radio will not be long enough to achieve the full collective range, the control ball is required to be mounted at a distance of 25-26mm from the center of the servo.
  • Page 25 Step 38 Rudder Linkage Robinison 22HP Manual The Rudder linkage changes the pitch of the tail rotor blades to increase or decrease the torque compensation to rotate the nose of the helicopter about the main shaft. Use a servo horn in the shape of a cross and find the correct arm that will sit at 90 degrees to the length of the servo by lightly pressing the servo horn over the output shaft on the servo.
  • Page 26 Step 39 Throttle Linkage Attach the throttle mount to the left side of the front mechanics with the knotch towards the starting shaft using two M3x10 socket cap screws in the front, threaded into one M3x30 hex spacer and one M3x8 socket cap screw and M3 locknut on the inside of the frames.
  • Page 27 Step 40 Muffler Attachment Robinison 22HP Manual With the narrow space between the mechanics and the fuselage, it is recommended to install the scale muffler Century has designed for scale fuselages. Attach the muffler to the engine with the screws provided with the muffler (Tip 1- using hi-temp Optional threadlock).
  • Page 28 STEP 42 Tail Pushrod Guide Positioning Insert three rudder pushrod guides positioned 7 3/4”, 14” and 21” from the front of the tail boom. Do not bond them at this time until the tail boom has been test fitted with the fiberglass tail boom. Connect the long rudder pushrod to the pushrod coupler and attach the 104mm pushrod.
  • Page 29 Robinison 22HP Manual Step 44 Preparing and painting the kit version. This section is written to cover painting and detailing of fiberglass components using in Century’s scale helicopter kits. Some included references may describe components of different kits, not exclusive to this instruction manual. Flexibility A wonderful attribute of fiberglass is in its flexibility.
  • Page 30 3. Once the detail parts have been built into the sub assemblies are ready to paint, use a filler in sections that have gaps or slight surface imperfections, occasionally there are voids (air bubbles in the resin) that occur near the surface that need to be filled.
  • Page 31 R22 Fiberglass Components Robinison 22HP Manual At this point, the flying mechanics should be assembled flight ready and possibly flight tested. The remaining items to be checked before proceding is the collective pitch setup and double check the servo throws for any binding. Now is the time to finalize the setup because access to the rotorhead is very restricted after the complete cabin and top shroud are assembled.
  • Page 32 STEP 47 Cutout Window & Navigation Lights #CN1076-2 Top window & Mark a line 3/16”[4mm] outside the molded line and Nav lights cut out the parts from the plastic sheet. Carefully continue to trim the parts as you test fit them to their final positions.
  • Page 33 Robinison 22HP Manual STEP 51 Cutout Window & Navigation Lights #CN1076-2 Navigation Lights Taking the navigation lights, continue trimming as they are fitted to the front of molded lights on the main cabin. Once trimmed, paint the navigation lights from the inside to preserve the high gloss outside surface.
  • Page 34 STEP 54 Front Landing Gear Mounts Slide one M3x9 plastic spacer onto the front landing gear stud followed by one M3x7 flat washer (additional washers may be necessary to lift the engine head from touching the landing gear), then the main mechanics and one M3 locknut and leave loose for now.
  • Page 35 STEP 57 Top Shroud Installation Robinison 22HP Manual Before the cabin can be installed the top shroud needs to be fitted. Remove the rotor head assembly and insert through the finished fiberglass shroud. Ensure that the washout arm pushrods are connected to the “A” pushrods and that the longer “C”...
  • Page 36 STEP 59 Receiver & Rx Battery Mounting #CN1076A Scale Accessory Kit (not included) The receiver and the receiver battery pack should be mounted in the bottom of cabin all the way in the front to balance the helicopter. Underneath the scale instru- ment panel (if purchased separately.
  • Page 37 STEP 61 Tail Gearbox Assembly Robinison 22HP Manual Position the output gear assembly into the right gear box half (insure the 2 bevel gears are meshed properly and the ball bearings are fully seated in their recesses) and liberally greased the gears before closing the gear box. Position the gear box halves over the holes in the end of the tail boom and secure with one M3x10 Socket Screw and M3 Locknut at the end of the gear box and one M3x16 Socket Screw and M3 Locknut at the center-top location.
  • Page 38 STEP 63 Scale Engine Exhaust CN1076A Scale Foam Tape Accessory Kit (not included) (Optional Scale Accessory Kit) Here If the optional accessory kit has been purchased the scale engine exhaust needs to be fitted before the cabin can be installed on the mechanics. Start by attaching the spring to the top surface of the engine exhaust.
  • Page 39 STEP 66 Attaching the Tail Boom Assembly Robinison 22HP Manual Once the foam insert is modified in the last step it can be positioned inside the fiberglass tail boom. Simply press the insert into the tail boom until it stops. The rudder pushrod is inserted into the smaller hole to the right of the central cutout.
  • Page 40 Final Adjustments - Radio Setup Now that the servo installation into the helicopter is finished the following pages should be reviewed. As various types of radios can be used to setup the helicopter, some of the following information may not apply.
  • Page 41 Before Flying your Helicopter Robinison 22HP Manual Before each flight, check that all bolts and screws are tight. Simply flying your helicopter, will loosen any screws which are not threadlocked or secured with a lock nut. First Flights For the beginner pilot, a training pod is strongly recommended to assist in learining to hover the helicopter with substantially reduced risk of crashing.
  • Page 42 Note 2: The tail rotor is mounted on the left side of the Tail Rotor Setup (rate gyro) helicopter, this is opposite to all our regular models. What separates airplane radio equipment from the helicopter version is in the control of the individual For each flight mode setting, there will be different curves discussed earlier and in the Revo-mixing Revo-mixing amounts.

  • Page 43: Pre-Flight Checklist

    Basic Hovering Robinison 22HP Manual When all is set, ready and checked, attach your training gear/pod and start the engine. (1) Place the helicopter pointing into the wind and stand behind the model about 15' away. (2) Always watch the nose of the helicopter, move the rudder left and the nose will move left. (3) Start by increasing the throttle slowly until the helicopter rises 2-6 inches off the ground then set it back down.
