You can also use a strand and bend a hook at one of the ends.
3 0 Boom & Tail Rotor 10 30 20 40 Tip : Slide the tail boom clamp over the boom. Unscrew one of the ball links on the tail control rod. Screw it back on the control rod after installing it. 3 Tip : Just install the screw, struts and nut temporary without tightening them to much. 5 Twist the tail belt 90° to the right before inserting it between the idler pulleys.
Use medium threadlock on all screws going into metal parts The boom support collar (7) has one beveled side. This must face outside. Be careful when fixing the tail boom braces and arrange the collars to them. 7 2 Beveled Side 5 Tip : Clip on the ball link on the tail control arm. Look which part of the tail control rod slides in the guide of the tail boom clamp to get the correct position for the heat shrink. Clip it off again and pull the tail control rod as far as possible to the rear.

Motor And Drive Tips Use medium threadlock on all screws going into metal parts Gear backlash adjustment: For smooth operation and performance, it is necessary to adjust the gear backlash properly. Excess gear backlash can cause premature gear wear and damage. Insufficient gear backlash can cause vibration, as well as overheating of the Motor and speed controller. Adjust the gear backlash by placing one piece of paper between the gears to set the distance.
Use blue threadlock on all screws going into metal parts. swing range Tip : If the rubber gets older, you can increase the tension by opening the two screws in the holder and sliding it to the rear in the long holes. Tip : Check the rubber from time to time for cracks and refractory material. Adjusting the belt tensioner is pretty easy. Just remove the rubber ring and adjust the tension as usual.

6 0 Suggested Equipment Position 10 20 30 40 Take some time for the wiring. Good fixing of the components and wires is important for a safe operation of your rc-equipment. Read the following wiring tips carefully. Brushless Motor Aileron Pitch Elevator Esc Rudder 12S Battery Receiver FBL Unit ESC To Motor Please read the manual of your FBL-Unit, transmitter and receiver very attentively.
7 0 Linkage Length & Setup Do not apply plier to resize Ball Links. Pliers could cause hidden damage to Ball Links and result in failure when operation. Use medium threadlock on all screws going into metal parts and nuts. Do not use pliers or screwdrivers to screw the ball links onto the linkages. It can damage the ball links and result in failure. Screw them on by hand or use special tools. 10 20 30 40 Compass Model ball links are build up on the tight side.
90 1 7 .5 ° Tail Setup At zero position, the servo arm should be at 90°. Use the best fitting servo arm and read the manual of your FBLUnit how to adjust the servo midposition. Adjust the linkage length so that the slider is parelel to the tail case side wall. It is important to limit the servo travel to the endpoints of the slider shown below. Too much travel can cause a stall and lead to a loss of tail authority.
Wiring Tips Never use RC-components with damaged wires. Check all wires for damaged isolation and breakage. Control all servo connectors for a tight fit and be sure no wire is loose in the connector. All wires must be protected against damage through sharp edges of the carbon frame and metal parts. Zip ties can also cause damage to the wires. Tip: Cut open a piece of fuel line to cover sharp edges. You can also use fuel lines to cover zip ties to prevent them from damaging the wires.
FBL Setup Tips Please read the manual for the current software version of your FBL-Unit carefully and follow all instructions. We can't give you any specific tips because most brands of FBL-Units change their software from time to time and your setup depends on many other factors like used blades and servos. Please check our website to find some setups from our Teampilots.
FBL Setup Tips 2 Double check the gyro directions of your fbl unit! Incorrect gyro directions will cause a crash! Checking the swasplate and tail gyro directions is a part of the preflight check! Look at the helicopter from the side to test the elevator gyro direction. Tilt the helicopter forwards as shown in the picture. The swashplate must tilt backwards. Tilt the helicopter backwards as shown in the picture. The swashplate must tilt forwards.
8 Control Check The picuture below shows how the swashplate has to move in mode 1 or mode 2.
9 0 Canopy 10 30 20 40 B Use AB Glue 4 A 1 2 B A Place the canopy onto the frames and mark the right position of the canopy insert. Mark the positions of the holes in the anopy on the Insert for drilling. Use a 2mm drill and drill straight through the insert. Use AB glue to fix the insert and screw it from the outside into the canopy. 3 5 Pos Description 1 2 3 4 5 M2.
11 Rotor Direction & Blades 0 10 30 20 40 When the main rotor spins clockwise the tail blades should turn clockwise as well watching the tail rotor from the tail fin side. If not, the belt is twisted and has to be corrected. Be sure that the main rotor and tail rotor blades are installed in the right direction. The leading edge has to show into the rotor directions. Do not overtighten the blades.
