.
Another sign of excess load on the servo is a pushrod that sticks or reaches the end of its travel before the servo does and
bends or arches up 'or down from the servo pushing it against a deadend. Locate the cause of overloads and eliminate
them. Overloaded servos will cause high battery drain, .with loss of control when the batteries run down. Servos may be
damaged by continual overload.
Double check all Control Hookups - No Binding, Rubbing, or Sticking
NOTE: Some RC sets have one reverse direction servo that will require an opposite hookup than that shown shown here
for logictrol radios.

Pushrods
A flexible steel cable pushrod with nylon outer tubing (SIGSH559 or DuBro No. 165) is recommended for hookup of the
throttle to the motor servo.
5/16" square balsa sticks are provided to make the fuselage pushrods that run to the
elevator and rudder. Bind the fittings to each end with heavy thread and epoxy glue.
Use threaded rods with RC links at the tail end of the pushrods so that trimming
adjustments can be quickly made. Straight pieces of 1/16" diameter wire are provided
for the other end of the pushrods to allow hookup with the servo arm. A variety of
quickly detachable pushrod retainers (Rocket City #07, SIGSH84, or solder clevises)
are available from the Sig Catalog for securing the pushrod wires to the servos. Or you
can make a "Z" bend in the end of the wires as shown.
The aileron pushrods are threaded rods with RC links - cut off and connected to the
servo output arm by one of the methods described above for the servo end of the fuselage pushrods. DuBro No. 103 or
Rocket City No, 05 strip aileron horn wire connectors are suggested to link the aileron pushrods to the wire torque rods.

Muffler Installation Notes
The prototype models of the Miniplane used the Tatone Side Mounted Manifold
#EM-SS. If fits completely inside the cowl and neatly directs the exhaust out two
rubber tubes exiting thru the bottom of the cowl. It muffles adaquately and doesn't
detract from the scale appearance of the model. Since the construction of the
prototypes, Tatone has introduced the #EM-40S, a slightly smaller version
manifold for .40 size engines. If you are using a .40 engine, the #EM-40S would
be our first recommendation. If you've got a .45 engine, you should get the #EM-
SS.
Large expansion chamber, flow-thru, or stack (DuBro MuffL-Aire) mufflers will
require an extension to locate completely outside of the cowl.

Pre-Flight
Balance the model at the C.G. point indicated on the plan. If it balances further back, add lead to the nose as necessary.
Trying to fly with the C.G. too far back is much more dangerous than the slight increase in wing loading caused by adding
lead to the nose. Balance with an empty fuel tank. When slightly nose heavy the model is much more stable and less likely
to snap roll or stall. The reaction to control movements is less sensitive so its not as easy to over control.
