Adjustments
The operating direction, neutral position, and steering angle of each servo are adjustable.
The basic linkage and adjustments, control layout, and servo, Rx and Nicad
installation should conform to the fuselage design drawings and kit instruction
manual. Be sure that the center of gravity is at the prescribed position.
Adjustment Procedure
Before making any adjustments, set all the SERVO REVERSING switches on the front
of the transmitter to the lower(NOR) position and set both Dual Rate
trimmers(AIL./ELV.) to the maximum ("10") point. (Set the switches and the trimmers
with a small screwdriver, etc.)
Turn on the transmitter and receiver power switches and make the following
adjustments:
1. Check the direction of operation of each servo.
If a servo operates in the wrong direction, switch its SERVO
REVERSING switch. (The direction of operation can be changed
without changing the linkage.) Pay special attention to the direction of the aileron. (See
page 14 for a transmitter operation instruction.)
2. Check the aileron, elevator, and rudder
neutral adjustment and left-right (up-down)
throw.
Check that when the Tx trim levers are in the
center, the linkage connection point is
perpendicular to the servo. In this position the
control surfaces (aileron, elevator, rudder, etc.)
must be neutral. If the neutral position of the
control surface has changed, reset it by
adjusting the length of the rod with the clevis.
When the throw is unsuitable (different from the deflection angle specified by the kit
instruction manual), adjust it by either changing the servo horn, the position of the
linkage on the servo horn or the linkage position on the control surface horn.
3. Check the engine throttle (speed adjustment) linkage.
Change the servo horn installation position and hole position so that the throttle is
opened fully when the throttle stick is set to HIGH (forward) and is closed fully when
the throttle stick and throttle trim are set for maximum slow (backward position and
lower position, respectively).
4. After all the linkages have been connected, recheck the operating direction,
throw, etc.
Before flight, adjust the aircraft in accordance with the kit and engine instruction
manuals.
5. Fly the plane and trim each control for straight and level flight.
