For any helicopter to perform to its full potential, it must be equipped with all the right gear (servos, batteries, receiver, etc). While other brands of equipment can be used, the equipment we recommend has the advantage of being extensively tested and proven effective. If you assemble this model according to this manual and use the recommended equipment, you should get top performance from your Kinetic .50.
We, as the manufacturer, provide you with a top quality, thoroughly tested ARF and instructions, but ultimately the quality and flyability of your finished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model.
IMPORTANT BUILDING NOTES KIT INSPECTION Before starting to build, take an inventory of the model to make sure it is complete, and inspect the parts to make sure they are of acceptable quality. If any parts are missing or are not of acceptable quality, or if you need assistance with assembly, contact Product Support. When reporting defective or missing parts, use the part names exactly as they are written in the Kit Contents list.

GY401 GYRO SETUP MAIN BLADES Warning: The blade root reinforcements must be glued to the main blades. Please inspect the blades for damage before assembling them. Do not exceed 1700 RPM with the wood blades or failure may occur. Blades are considered consumable items and should be discarded if there is any sign of damage. If you are using a digital servo such as the Futaba S9254 or S9253, the DS mode switch should be “ON”. Otherwise, set it to “OFF”. The “DIR” should be set to “NOR” or “OFF”.
BLADE BALANCING Note: All main blades must be balanced before use. We recommend using the Heli-Max Blade Balancer (HMXE4855). ❏ 1. Apply the two colored stripe decals to the tips of your main rotor blades (for use in blade tracking later on). ❏ 2. Prepare the balancer for use by rotating the brass adjustment dial until the bubble in the vial indicates level. Make sure that the blade balancer does not move during this process. ❏ 3.
❏ 5. Position the second blade on the tray, with the mark at the center. Add balancing or electrical tape to the lighter end until the bubble indicates that both sides are level. The C.G. of both blades is now matched. If the tape ends overlap, make sure the overlapping end points to the trailing edge of the blade. ❏ 7. Add tape to the C.G. of the lighter blade until the bubble level indicates that the two blades balance.
FINAL ASSEMBLY FUEL LINES ❏ 2. Turn on the transmitter and receiver. Move the collective stick to full throttle. Place the pitch gauge on the blade as shown and set it to +10°. Align the top (or bottom) of the pitch gauge with the flybar. If necessary, adjust the long linkage between the mixer and the swashplate. Once the correct pitch has been established, adjust the length of the linkage on the opposite side to match. ❏ Cut a piece of 4" [102mm] fuel line for the carburetor pickup line and install.
❏ 2. Trim the front of the body as shown above. Make a clean ❏ 5. Once the body is installed, trim and test fit the windshield. When satisfied with the fit, drill 1/16" [1.5mm] holes at the locations shown and use 2x3mm self-tapping screw to attach the windshield. Repeat for the other side of the body. cut by making several passes with a hobby knife. Mark the body 5/8" [16mm] up from the back edge and 5/8" [16mm] right. Drill 1/4" [6.4mm] holes for the rubber grommets. Install the grommets into the body.
Left Cyclic PREPARE FOR FLIGHT CHECK THE CONTROL DIRECTIONS Turn on the transmitter and allow the gyro 5 seconds to initialize before moving the helicopter or operating the sticks. If everything has been adjusted properly the swashplate should be level with the main frame when the sticks are centered. ❏ View the helicopter from the rear. Pushing the right stick to the left should make the swashplate tilt to the left. Forward Cyclic Right Cyclic ❏ Look at the helicopter from the right side.
Left Tail Rotor ❏ When the left (collective) stick is pushed forward, the swashplate should move up and the carburetor should open. ❏ When the left (tail rotor) stick is moved to the left, the tail pitch slider should move to the right as shown. Right Tail Rotor Descend Collective ❏ When the left (tail rotor) stick is moved to the right, the tail pitch slider should move to the left as shown.
RANGE CHECK Ground check the range of your radio before the first flight of the day. With the transmitter antenna collapsed and the receiver and transmitter “ON”, you should be able to walk at least 100 feet away from the model and still have control. Have an assistant stand by your model and tell you what the servos are doing while you work the controls. If the controls do not respond correctly, do not fly! Find and correct the problem first.
Left Cyclic FLYING Please try to find a local club (check www.modelaircraft.org for listings) or find an experienced modeler for help before starting to fly. There are a lot of mistakes that can be made during the assembly of helicopters that an experienced modeler can catch. They will help you get the model setup properly and verify that the model is trimmed out and ready for your first flight. The web sites listed below are discussion forums for R/C Helicopters and Planes.
Descend Collective TRAINING GEAR If you have never flown a helicopter before, consider purchasing training gear. It not only helps prevent crashes and tip-overs, but prevents damage by softening not-so-perfect landings.The HeliMax Training Gear (HMXE2025) is highly recommended. When the left (collective) stick is moved downward, the helicopter will descend. FLYING CONDITIONS During your first flight, it is very helpful to fly in light winds and have a helper to keep an eye on things around you.
ADJUST BLADE TRACKING moving the helicopter to the side and turning back. Then fly back to the other side in straight lines. Once you become comfortable with those you can try rotating the helicopter 360°, which is called a pirouette. The helicopter can drift during pirouettes, so make sure you have plenty of room to perform the maneuver. After pirouettes, it is time to move onto nose-in hovering. It is best to wait for a calm day. Take off and climb to 15'.
continues to fly inverted, you will need to start adding in negative (–) collective (or pull the collective stick back towards you) to maintain altitude. As the model transitions back to vertical, again bring the collective stick back to the middle and start adding in positive (+) collective as the model comes back to the upright position.
