Safety Instruction of Ni-MH Battery
01. Batteries should be charged prior to use.
02. When using a new battery for the first time or after long term storage, please fully charge the battery before use.
03. Use the correct charger for Ni-Cd or Ni-MH batteries.
04 .Do not reverse charge batteries.
05. Do not short circuit batteries, permanent damage to batteries may result.
06. Do not incinerate or mutilate batteries, may burst or release toxic material.
07. Do not solder directly to cells or batteries.
08. Do not subject batteries to adverse condition such as extreme temperature, deep cycling and excessive Overcharge/overdischarge.
09. Store batteries in a cool dry place.
10. Do not mix up this battery with other brands such as alkaline Zinc battery。
11. Do not mix new batteries in use with semi-used batteries, overdischarge may occur.
12. Avoid batteries being used in an airtight compartment. Ventilation should be provided inside the battery compartment; otherwise batteries may generate hydrogen gas, which could cause an explosion if exposed to an ignition source.
13. When connecting a battery pack to a charger, ensure correct polarity.
14. If find any noise, excessive temperature or leakage from a battery, please stop its use.
15. When the battery is hot, please do not touch it and handle it, until it has cooled down.
16. Do not remove the outer sleeve from a battery pack nor cut into its housing.
17. When find battery power down during use, please switch off the device to avoid overdischarge.
18. When not using a battery, disconnect it from the device.
19. Unplug a battery by holding the connector itself and not by pulling at its cord.
20. After use, if the battery is hot, before recharging it, allow it to cool in a well-ventilated place out of direct sunlight.
21. Never put a battery into water or seawater.
22. During long term storage, battery should be charged and discharged once every half a year.
23. Do not attempt to take batteries apart or subject them to pressure or impact. Heat may be generated or fire may result. The alkaline electrolyte is harmful to eyes and skin, and it may damage clothing upon contact.
24. Keep away from children. If swallowed, contact a physician at once.
CAUTION
1. Never charge the battery at more than 1 amp.
2. Never discharge the battery at more than 5c and never take the voltage lower than 9v as
this will damage the battery.
3. For full flight time to be achieved please cycle the cells through three flights.

Center of Gravity Check
Please check the CG before heading to the flying fileld. The center of gravity for your
Decathlon should fall within the range as indicated by the arrows. For your initial flights, we suggest that you balance the model toward the front fo the wing. After you become more familiar with the airplane, you can move the
CG more aft.However,under no circumstances should the CG fall behind(toward the rudder) the rear mark.If necessary, adjust the CG by moving your receiver or adding weight to the nose or tail of the airplane.
