|Before installing the aileron servo tape the wire as shown. Also with all links, the measurements given are from center of each hole. And don't forget, label side out on the links.|
Start with the Aileron servo. This is the servo that will move
the heli left/right. Install the rubber grommets on the servo
then the brass eyelits. The flared end of the eyelits need to be
on the bottom. Mount the servo in the middle of the pitch arm.
Install it so the spline is toward the main shaft. Use four
screws (1) to hold the servo in place. Next make up two links 72mm
long and snap them in place on the aileron levers, but not on the
servo. In fact it would be better to wait until you do the radio
setup before you place the balls on the servo arms. When you are
ready for radio setup, you need to go to RaptorTechnique.com\radiosetup.htm
For each of the next servos, first install the grommets, then the
brass eyelits (remember flared side down), install each with the
servo spline toward the main shaft, and secure the servo by using
four (1) screws to hold it in place. The servo in the top slot of
the servo tray will be the elevator. It moves the helicopter
forward/backward. Mount so the servo top is facing the right side.
Next down is the collective servo, this makes the helicopter go
up/down. Mount so the servo top is facing the left side. Next
down is the rudder, make the top face the right side. The one on
the bottom is the throttle, mount so the top is facing the left
At this time you can go ahead and make up the links, but some may need slight adjustments during radio setup. For the Aileron servo make two links each 72mm long. The elevator links should be 84mm. The collective is 53mm. And the throttle is 77mm. For the rudder rod (7), insert it from the back of the frameset, through the two loops on the right side, then install the link. When joining the front and back rudder rods together using the coupler (8), make sure the end of each rod extends past the hole. It is sometimes easy to be tricked because the end of the rod gets caught up on the holes and it makes you think it is in as far as it can go. If either rod does not extend past the hole then there is a chance it will come out in flight (not a good thing, better know how to auto). And be sure to blue loctite the two set screws. After joining these two rods you need to align the tail boom guides to give the least amount of resistance. First start with the front guide, slide the rod toward the back as far as it will go, then position the guide so that it is 5mm behind that. Rotate it and the rest of the guides so the rod is straight. Slide the linkage to test the positions. You can sight down the back of the linkage to help tell if it's straight. Once you find the best position use a drop of thin CA between each guide and the tailboom to prevent it from rotating later.
Later when you do radio setup, you find the correct hole in the servo arm to use then insert the ball (9) with bolt (2) and nut (3). Use blue loctite on each 2mm nut (3).
