Great Planes de Havilland Tiger Moth EP ARF - GPMA1134 - Manual (Page 13)

This is where your Tiger Moth should balance for the fi rst
fl ights. Later, you may experiment by shifting the C.G. 3/16"
[4.8mm] forward or 3/16" [4.8mm] back to change the
fl ying characteristics. Moving the C.G. forward will improve
the smoothness and stability and allow your Tiger Moth to
perform tighter turns, but the model will fl y slightly faster.
Moving the C.G. aft allows the model to fl y more slowly,
but will require slightly more pilot control in tightly-banked
turns. In any case, start at the recommended balance
point and do not at any time balance the model outside
the specifi ed range.
If the model is balanced properly it should rest level when
viewed from the side. If the tail is down the model is “tail-
heavy” and nose weight will be required. If the nose drops
the model is “nose-heavy” and tail weight will be required. If
you are using the components recommended in this manual
it is likely that the model will balance at the recommended
C.G. location, or possibly require 1/4 to 3/8 oz. [7g to 11g] of
nose weight.
❏
5. If any weight is required to get the model to balance,
fi rst determine how much by placing segments of Great
Planes “stick-on” lead (GPMQ4485) over the location on the
fuselage where it will be attached inside and rechecking the
balance. A good place to attach tail weight is to the inside of
one of the fuselage sides under the horizontal stab. A good
place to attach nose weight is to the top of the “motor box”
right behind the fi rewall. Do not attach nose weight to the
cowl because it will cause stress around the mounting screw
holes.
❏
6. Once you know how much weight is required, attach it
in the fuselage. Then, recheck the balance.
Charge the Batteries
Follow the battery charging instructions that came with
your radio control system to charge the transmitter
batteries. You should always charge your transmitter the
night before fl ying, and at other times as recommended by
the radio manufacturer.
CAUTION: Unless the instructions that came with your
radio system state differently, the initial charge on new
transmitter and receiver batteries should be done for 15
hours using the slow-charger that came with the radio
system. This will “condition” the batteries so that the next
charge may be done using the fast-charger of your choice.
If the initial charge is done with a fast-charger the batteries
may not reach their full capacity and you may be fl ying with
batteries that are only partially charged.
MOTOR SAFETY PRECAUTIONS
Failure to follow these safety precautions may result in
severe injury to yourself and others.
●
Use safety glasses when starting or running motors.
●
Do not run the motor in an area of loose gravel or
sand; the propeller may throw such material in your
face or eyes.
●
Keep your face and body as well as all spectators
away from the plane of rotation of the propeller as
you start and run the motor.
●
Keep loose clothing, shirt sleeves, ties, scarfs, long
hair or loose objects such as pencils or screwdrivers
that may fall out of shirt or jacket pockets away from
the prop.
