Range Checking Before Flight; Getting Ready To Fly - Sapac TL 2000 Operation And Assembly Instructions

reverse the connection to rectify. Plug the adapter into the charger for charging. The charger may also be powered from
a 12 Vlt. DC battery – like a car battery, to enable charging away from the home. Attach the lead with "alligator" clips to
the DC battery ( RED to + BLACK to - )
Then plug into the Purple charger for charging.
It is highly recommended to use a fireproof dish or bowl to contain the battery while charging - see photo – this is a
safety precaution in case of a fire. Always Charge the battery outside if possible and never leave unattended. Disconnect
the battery if it gets hot.
SAFETY PRECAUTIONS for LiPo Batteries
•
Never leave Lithium Polymer batteries unattended whilst charging.
•
Never charge Lithium Polymer batteries inside a model; hot batteries can cause fires.
•
Never charge Lithium Polymer batteries inside a motor vehicle.
•
Never charge Lithium Polymer batteries on any surface which can catch fire e.g. wooden benches.
•
Do not dispose of batteries in a fire.
•
Do not allow batteries to get wet.
•
Do not use the batteries with positive and negative terminals reversed.
•
Do not short circuit the battery.
•
Do not pierce the battery or subject it to heavy knocks or impacts.
•
Do not use or store the battery inside motor vehicles during hot weather. Doing so may cause the battery to
overheat, risking fire or explosion.
•
If your battery balloons in size, is punctured or is malformed, take precautions to get the battery to a non-flammable
area for at least one hour. IN CASE OF FIRE. After several hours place the battery in salt water.

RANGE CHECKING BEFORE FLIGHT

Before your first flight, it is a very good idea to check whether you will have the
maximum range possible. This is achieved by getting a helper to hold the plane while
you walk away from the plane while the set and plane both turned on and the aerial
on the transmitter fully down. With everything set up correctly you should be able to
walk 20 to 30 paces away before the servos begin to twitch around. If you only
achieve a short distance before erratic behaviour of the servos or motor then you
must not fly and check out and rectify the problem before attempting to fly. Re-routing
the aerial away from the battery and servo/ motor leads will often help!

GETTING READY TO FLY

Always ensure that the transmitter is switched on, that the antenna is extended fully , that the throttle lever is set at its
lowest point ( stick to the bottom on the gimbal ) and the model is being held securely before connecting the battery, this
will prevent unexpected start ups which could cause injury.
OK, so having done that, the battery can be placed in its compartment under the nose and its red plug connected to the
socket inside. After a pause you will hear some "beeping" telling you that the battery, the electronic speed control and the
motor are all in communication. When the beeping stops, slowly advancing the throttle will cause the motor to start and
continue to speed up until full throttle is reached.
Having checked the motor, stop it by bringing the throttle lever back to full low and then, by moving the elevator, aileron
and rudder sticks, check that all surfaces move in the correct direction and by the required amount. If any of these move
in the wrong direction there are reversing switches on the front of the transmitter to correct the situation, With the trims,
(they are the small sliders alongside the sticks), in the central position, check that the ailerons, rudder and elevator are
properly aligned; if not, make adjustments to the appropriate clevises. Having the surfaces properly aligned with the trims
in the central position will ensure that the model on its first flight will be near to being "in trim" and any minor out of trim
condition will then be correctable by use of the trim sliders. You may wish to engage the assistance of a modeller with
some R/C experience to guide you through this all important phase and also to cast his eye over the model to ensure all
is correct.
The first task is to range check the radio equipment. Go to an area clear of trees and metal fences, like the middle of a
sports field to ensure clear reception.
The Charger operates on 12 Vlt DC. The
included 240 to 12 Volt adapter may be
used to power the charger from your
home power points. Attach the GREEN
plug from the selection and fit to the
adapter lead. If the polarity is wrong – the
RED charger light will not illuminate –
