Then mount the swashplate support (51) and the upper bearing (54A) to the servo support (50). Mount the middle bearing (54B) into the servo support (50). Afterwards mount the preassembled servo support (50) with three screws to the upper main frame (55). Finally mount the two belt guide rollers (53) and the bearings (XX) by using screw lock glue as shown to the upper main frame (50). Mount the main gear holder (59) to the main gear (60) with three screws. Mount the inner spacer (61) and one way bearing (62) into the main gear holder (59). Afterwards mount the complete main gear by using the main axis bolt (63) to the main axis (56). Mount the belt gear (57) to the main axis (56) using another main axis bolt (58). Finally mount the main axis to the preassembled lower body from step 6. Align the preassembled tail boom from step 10 and the belt onto the main axis. In the next step the tail boom will be screwed to the main frame so make sure that the belt is not twisted inside the tail boom and that main and tail rotor rotating directions are correct. page -8-

9 STEP 14 - Main frame mount - open BAG 12 STEP 15 - Rotor head mount - open BAG 13 STEP 16 - Cyclic control connectors - open BAG 14 Mount the preassembled upper main frame from step 11 and the tail boom with two screws to the lower body from step 12. Mount the motor pinion (66) to the motor (64). Afterwards mount the motor (64) with two screws by using the two motor spacers (65).Finally mount the retaining ring (67) with the screw. Make sure that the axis is fixed through the retaining ring and that there is no game at the main axis in the axial direction. Mount the swashplate (70) to the main axis of the preassembled body from step 14. Put the rotorhead fixing ring (49) and the the O-stabilizer (68) together with the rotorhead from step 3 onto the axis and fix the rotorhead from step 2 with the main axis bolt (69) and tighten the fixing ring (49) screw. Use the steering connectors (71) by passing them through (69) to connect the swashplate with the rotorhead as shown. page -9-

10 STEP 17 - Collective pitch connector mount STEP 18 - Servo mount Modify servos Connect the pitch connectors (72) as shown to the swashplate and the inner ball links of the translation levers (11). (Picture doesn t show the rotating frame in order to easy the view) Mount the servos as shown on the picture with a double side adhesive foam tape. A long half servo arm may have to be created by cutting a full or cross arm. After testing the radio equipment the servos will be in their center position. Remove the servo retaining screw and the orignial servo arm. Replace the original arm with one of the long half arms. Some servo arms require widening the hole in the arm in order for them to accept the Mosquitos pushrods (74) using a #55 drill bit (1.34mm or ). Leave the servos in center position for the following step. 1&2 Trim both servo mounting flanges from each of the three servos. Before installing your will need to remove the pushrods form the swashplate of the helicopter. Keep the pushrods on the side until you install the correct servo arms (next step). page -10-

11 STEP 19 - Pushrod mounting STEP 20 - Rotor blade mount - open BAG 15 Premount the pushrods (74+73) by screwing the metal rod (74) into the to the ball link connectors (73). You may need to widen the ball link connectors (73) tip a little in order to ease the metal rod (74) mounting by using a cutting knive. Turn it a little inside the mounting hole to widen it. After mount the three pushrods (74+73) into the servo arm and connect the other end with the balls link of the swashplate (70). Make sure that all connectors are at the same length and that the centered servo arm position will also center the swashplate s travel from high to low pitch position. Mount the main rotor blades (75) by using the screws. Make sure that both rotorblades are equally tight holded by the screw. To do so after mounting the rotorblades straighten them, put the helicopter to the floor and fold both rotorblades towards you. Check if the main axis itself will turn in any direction. If so, adjust the rotor blade holding screws tightness until folding both rotorblades will not force the main axis to turn in any way. page -11-

12 STEP 21 - Tail servo mount - open BAG 16 STEP 22 - Tail support mount End of mechanical kit assembly Mount the tail servo with the servo holing screws (not included in this kit) as shown to the servo holders (46). Use mount the ball link (78) to the servo arm as shown. Mount the two ball link connectors (77) to both ends of the tail servo rod (76). Connect the tail servo rods ends with the ball links at the servo and at the tail frame. Eventually adjust the position of the servo holders (46), so that the center tail servo position will result in the center position of the pitch shifter (38); afterwards thighten the servo holder screws. Finally clip the tail servo rod (76) into the two tail rod guides. Mount both tail support bars (79) as shown. Align the crosswing and thighten its holgind screws. You can use hot glue or component glue to fix the bars into both ends supports (recommended for 3D flights). page -12-

13 5. Connection and diagnostics for the electronic components This diagram represents the overall connections for wiring the MOSQUITO correctly (if using Futaba or Hitec). This diagram includes the separate connections pictured in the follwing page. Testing and preparation of radio equipment Please don t skip this section!! Before modifying or installing any radio gear, plase take a few minutes to test everything as shown. Time spent becoming familiar with the equipment and testing all the components can prevent difficulty. 1. Intall the crystals into the transmitter and receiver. Be certain that the channel frequency matches. 2. Note that all electroincs plug into the receiver with the wires as pictured (orange wire faces receiver label). Follow the diagram for each electronic connection. Once the electronics system is connected and the transmitter is turned on, follwo this step-by-step process to check your equipment. STEP by STEP component test: 1. Turn on the transmitter test if the transmitter is functioning normally. Make sure you fixed the helicopter so it won t be able to take off in any case of malfunction. Mind your hands when you connect the battery! 2.Plug the battery into your speed controller. Wait for the speed controller and gyro to initialize before moving the helicopter. 3. Move the aileron, elevator pitch and rudder channels to make sure the servos work. With the gyro connected properly the rudder servo should move when turning the helicopter. page -13-

The stickers should be mounted as shown in the following picture page -18-

19 12. Additional information about helicopter mechanics. Your MOSQUITO 3D PRO is a full F3C cabaple helicopter. But it depends on the user and its adjustment abilities to gain a maximum performance and long spareparts lifetime. In the following we provide some useful informations about above mentionend. A - Tight screws: As a helicopter depends like any flying object on proper mechanic funtion, you should make sure before each flight that it s screws are tightened. The most important places are where most forces stress the connection such as the rotorhead, motor, belt drive and tail frame screws. If a screw which is fitted into the plastic parts is overtightened, please exchange that sparepart. B - Balance main rotor blades: As any machince produced rotor blade will slightly differ in weight and lentgh it is necessary to balance the blades. You might use a so called rotor blade balance, but a long screw, two washers and nuts do it as well. Mount both blades directly to each other, straighten them and place the long screw ends onto a U shaped item, so that the blades can freely swing. One of the two blades will now, as it is more heavy than the other, swing downwards. To compensate the misbalance just add small stripes of tape at the outer end of the lighter rotor blade. C - Main rotor pitch You will need to buy a pitch gauge in order to check the pitc. There are some carton shapes to cut out on the internet, but thats not really working out. Mount the pitch gauge and make sure that - when the three servos are in the center position - the pitch is at 0. If you use a computer radio, you can adjust the pitch through the radio. In any other case - the hover pitch is to be adjusted around 9, depending on the battery + electronics weight you mounted to the MOSQUITO. D - Main rotor blades tracking: As the pitch of both rotor blades is changeable through the CCPM mechanic it is really necessary that their track (or parallel pitch) is equalized. In order to adjust the tracking (thats to be done by adjusting one of the two pitch connectors (9) ) it is necessary to slowly rotate the blades. Before doing that, make sure that there is one of the rotorblades marked with a colored tape near the tip of the rotorblade. While letting them rotate at slow speed you need to look directly into the rotation layer (wear eye protection glasses!). You will see now if the white-color-white flickering (as you repeatedly see the colored and the uncolored blade) will match in its position or not. If not, adjust the rotorblade s pitch connector until you reach a satisfatory result. C - Tail belt tensioning The MOSQUITO s tail belt is fibre-reinforced in order to withstand the forces. A long service life is only guaranteed if the belt s tension is properly adjusted. As the belt will warm up while flying, it will also enlarge slightly. Therefore a cold belt has to be tensioned a little more than a warm one. Please check the tension at the guide rollers (53) by pressing with your finger on it. You shouldn t be able to push it more than 3mm away from that guide roller. Please also check the state of your belt for missing teeth or other damages regularly and replace it. D - Gear spacing It is important to have the gear mesh (teeth) set correctly. If it mesh too thight, it will rob power and may overheat the motor. If it is too loose, it will probalby strip the gears. A good way of setting gear mesh is to insert some very thin paper between pinoin and spur gear as you tighten the motor mount screws.
