16. FINAL CHECKS (BEFORE YOU FLY)
Range Test your aircraft, walk 30 metres away from
your aircraft and check that you still have full
control. If you do not, reposition the RX inside the
fuselage and repeat test.
Confirm that your Flight Battery is fully
charged, we recommend that you check
this with a battery checker such as the
Etronix Battery Doctor (Part Number
ET0500).
Confirm that all hardware is fitted securely,
especially control horns, clevices.
Surfaces move in the correct direction.
Transmitter is fully charged, trims and
switches are in the correct place.
FLYING THE MX2
1. You will find that the ground handling of the MX2
is great, especially if you select high rudder rates to
give you maxium movement before you
take off.
2. Gently roll the throttle to about half for a smooth
scale take off.
3. The aircraft will perform the entire aerobatic
catalogue but you will have to mangage your power
and energy.
4. Landing the MX2 on the strip is easy, just line it
up on the runway and bring it in, when you
approach ground effect chop the throttle and
gradually bleed the speed off with the elevator.
Three point landings are best with this type of
aircraft.
5. The Rudder is extremely effective in the air, I
would suggest that if you use your own radio you
dial in a small amount of Expo to help keep things
smooth.
6. To get the best out of this airframe we have
experimented with programmable mixes to
compensate for Rudder to pitch and Rudder to roll
coupling.
7. Have your high Rates on one swich so that you
can instantly switch between them. I always have
my aileron rates set high so that I can initiate
Snap rolls with no switching needed. High rates is
for High Alpaha and Prop Hanging.
We found the following setup virtually eliminates
any coupling:
PMIX 1
To Eliminate PITCH changes when inputting
Rudder.
Master: Rudder
Slave: Elevator
Movements: Right Rudder to give 14% of Up
Elevator
Left Rudder to give 14% of Up
Elevator
PMIX 2
To Eliminate ROLL when inputting the Rudder.
Master: Rudder
Slave: Aileron
Movements: Right Rudder to give 5% of Right
Aileron
Left Rudder to give 5% of Left
Aileron

TOP GUN PARKFLITE LIPO CELLS
IMPORTANT SAFETY INSTURCTIONS AND
WARNINGS – READ BEFORE USE
Lithium Polymer batteries can be volatile. Whilst some
of the instances listed below are rare, they can occur
and it is important for you to be aware of how to handle
such situations. Failure to read and follow the below
instructions may result in fire, personal injury and
damage to property if charged or used improperly.
Top Gun Park Flite, its distributers or retailers assume
no liability for failures to comply with these warnings
and safety guidelines.
By using this battery, the buyer assumes all risks
associated with lithium batteries. If you do not agree
with these conditions, return the battery immediately
before use.
The final use and preparation of the battery pack is
ultimately beyond our control and those of our
representatives and retailers. Your decision to use this
product incorporates your agreement that you have read
and understood the safety precautions listed below an
on each battery pack, and that you agree to accept full
responsibility for any injury, loss or damage resulting
from all circumstances surrounding your use or misuse
of this product.
STORAGE AND TRANSPORTATION
1) Store the battery at room temperature between 5 and
26˚C.
2) Do not expose battery pack to direct sunlight (heat)
for extended periods.
3) When transporting or temporarily storing in a vehicle,
temperatures should between –6˚C to 60˚C and ensure
that the battery terminals can’t short.
4) Storing battery temperatures greater than 76˚C for
extended periods (more than 2 hours) may cause
damage to the battery and may lead to a possible fire.
5) Always store the batteries in a fireproof box or LiPo
Bag.
PRODUCT WARRANTY OF BATTERIES
Product warranty is limited to original defects in
material and workmanship. Warranty does not cover
collateral damage. Due to the nature and use of the
battery there is no term warranty. Misuse, abuse,
incorrect charging and other inappropriate use of this
product are not covered under warranty.
GENERAL GUIDELINES AND WARNINGS
FOR LIPO BATTERIES
1. Only use the supplied specific lithium charger. Do not
use a NiMH or NiCd charger – Failure to do so may
cause fire, which may result in personal injury and
property damage.
2. Never charge batteries unattended. When charging
LiPo batteries you should always remain in constant
observation to monitor the charging process and react
to potential problems that may occur.
3. If at any time you witness a battery starting to
balloon or swell up, discontinue the charging process
immediately, disconnect the battery and observe it in a
safe place for approximately 15 minutes. The battery
electrolyte may leak, and the reaction with the air may
cause the chemicals to ignite, resulting in a fire.
4. Since delayed chemical reaction can occur, it is best
to observe it in a safe place for approximately 15
minutes should any damage occur to your battery.
5. Additionally, if a short occurs and contact is made
with metal (such as rings on your hand), severe injuries
may occur due to the conductibility of electric current.
6. Do not bend, crush, drill or cut open your battery.
In the event of a crash, you must remove the battery for
observation and in a place where it is away from
combustible material for approximately 15 minutes.
7. Never store or charge the battery pack inside your
car in extreme temperatures, since extreme
temperatures it could ignite. Do not expose the battery
to fire or any temperatures exceeding 76˚C.
8. After use please let the battery cool to ambient
temperature before charging.
9. Do not over-discharge the battery. Discharging the
battery below 3 volts per cell may cause damage to the
pack resulting in reduced performance and duration.
When a drop in power occurs in flight land immediately
to avoid discharging the batteries below 3 Volts per cell.
10. Should you get the electrolyte on your skin wash it
off immediately with soap and water. Should you get the
electrolyte in your eyes flush generously with water for
10 minutes and seek medical attention.
11. 3.7 Volts is the average voltage of each cell; a LiPo
can be charged up to 4.2 Volts and discharged to 3
Volts, any higher or lower in voltage and the cell will
almost certainly be damaged and may become unstable.
This can be very dangerous as there is a fire risk.
12. If disposing of a LiPo battery proceed as follows:
Submerse the battery into a container filled with about
10 litres of salt water (one cup of salt in 10L).
Leave the battery submerged for 2 weeks, this will
slowly and safely discharge the battery until the voltage
has dropped to zero volts which eliminates the risk of
any chemical reaction. It can then be disposed off in the
general waste collection.
