Install The Radio - THUNDER TIGER Tiger Trainer MK II Assembly Manual

ASSEMBLY
11. Complete the spinner installation. Loosen the prop nut and
rotate the spinner backplate so the two little posts rest against the
prop trailing edge; then tighten the prop nut. Use the two special
screws furnished to secure the spinner nose cone onto the backplate.
12. Secure the wheel onto the nose gear using the wheel collar
and set screw furnished. Make sure it turns freely.
C. Install the Radio
1. Refer to your radio system's instruction manual for complete
installation instructions. Prepare your servos by putting the rubber
grommets in the mounting ears. Install three of the servos in the fuse-
lage's servo tray, positioning them as shown. As you install each servo,
pass the connector end of the cable through to the forward compart-
ment so you can plug into the receiver later. Drill 1/16" pilot holes
before securing the servos using the screws furnished with your radio.
Next, cut a hole in the side of the fuselage and drill holes to mount the
switch, using the switch cover as a template. Mount the switch.

2. Hooking your servos to the link-
age is done according to the above
drawing. The pushrods are secured to
the servo wheels or arms with "z"
bends. (Note: the elevator pushrod has
two rods exiting the tail; the rudder
pushrod has only one.)
The throttle pushrod and the
nosegear pushrod are connected to the
servos with "EZ" connectors. The "EZ"
Connector barrel is attached to the
servo wheel/arm with the furnished
nut. The pushrod is secured in the barrel with a set screw and Allen
wrench, which makes the pushrod length easily adjustable.
3. Install your aileron servo in the tray that is glued into the left
wing half as shown. Linkage to the ailerons is done via two pushrods
with a "z" bend on the servo end and a nylon clevis on the aileron
torque rod end. Hook up the "z" bend ends of the two aileron
pushrods to both sides of the servo wheel/arm and secure the
wheel/arm to the servo. Snap the clevis onto the nylon torque rod
horn on the left aileron. You will attach the clevis to the right aileron
torque rod horn when the wing is joined.
4. Plug the servos into the proper receiver outlets. Wrap the
receiver and battery pack in at least 1/4" thick foam. Route the receiv-
er antenna out the rear of the wing opening; if you wish, drill a 1/16"
hole in the rear window for an antenna exit. MAKE SURE you don't
put any strain on the antenna wire coming out of the receiver; have
some sort of strain relief. Also, make sure you don't lengthen or short-
en the antenna; performance will be affected. Continue the antenna
wire to the top of the fin and hook with a straight pin and a small rub-
ber band. Any excess can just trail out out the back of the plane.
