ELECTRIC MOTOR SAFETY

PRECAUTIONS

  The motor gets HOT! Do not touch it during or right after 

operation.

  When working on your plane, remove the propeller if the 

motor batteries will be connected.

  Always remove the motor batteries when charging.

  Follow the charging instructions included with your charger 

for charging LiPo batteries. LiPo batteries can cause 
serious damage if misused. 

  Once the motor batteries are connected the electric motor 

can start at any time. Make sure the fail safe is set on your 
radio to prevent the motor from starting if the signal is lost. 

 

 ALWAYS

 unplug the motor batteries fi rst.

 

 NEVER

 switch off the transmitter with the motor batteries 

plugged in.

  

WARNING:

 Read the entire instruction sheet included with 

your motor batteries. Failure to follow the instructions 

could cause permanent damage to the battery and its 
surroundings and cause bodily harm!

  ONLY

 use a LiPo approved charger. 

  

NEVER

 use a NiCd/NiMH peak charger to charge a LiPo 

battery.

  

NEVER

 charge in excess of 4.20V per cell.

 

 ONLY

 charge through the “charge” lead. 

  

NEVER

 charge through the “discharge” lead.

  

NEVER

 charge at currents greater than 1C unless the 

battery is rated for a higher charge rate.

  

ALWAYS

 set the charger’s output volts to match the 

battery volts.

 

 ALWAYS

 charge a LiPo battery in a fi reproof location.

  

NEVER

 trickle charge a LiPo battery.

  

NEVER

 allow the battery temperature to exceed 150° F 

(65° C).

  

NEVER

 disassemble or modify the pack wiring in any way 

or puncture the cells.

  

NEVER

 discharge below 2.7V per cell.

  

NEVER

 place the battery or charger on combustible 

materials or leave it unattended during charge or discharge. 

  

ALWAYS

 KEEP OUT OF THE REACH OF CHILDREN.

  

NEVER

 charge the battery in the plane.

 

 ALWAYS

 remove the battery from the plane after a crash. 

Set it aside in a safe location for at least 20 minutes. If 
the battery is damaged in the crash it could catch fi re. 

  If the battery starts to swell, quickly move the battery to 

a safe location, preferably outside. Place it in a bucket, 
covering the battery with sand. Never use water to try 
and put out a LiPo fi re. 

WARNING:

 

For brushless electric motors, never have the 

motor battery connected to the ESC without the transmitter 
turned on – after each fl ight (or any time after running the 
motor), 

always

 disconnect the battery 

before

 turning off 

the transmitter. And when ready to fl y (or whenever running 
the motor for any reason), always turn on the transmitter 
fi rst before connecting the motor battery.

Also make certain your failsafe is programmed correctly 
so in the event the receiver ever loses signal (or, if you 
inadvertently turn off the transmitter before disconnecting 
the battery or vice-versa) the motor will not turn. Follow 
the instructions that came with your radio control system 
to check and set the failsafe.

The recommended RimFire .80 is rated for 52A constant 

current and 65A surge current. Powered by a 6S LiPo on 
an APC 14 x 10E it draws about 55A static and momentary, 
maximum peaks of about 53A in the air, but averages a 
little less than 30A through a “normal” flight. This is an 
absolutely safe and conservative propeller choice and flies 
the Kaos well – it can be zoomed around boring holes in the 
sky, or flown like a classic pattern plane executing graceful 
maneuvers with conservative throttle management. Vertical 
performance is unlimited or virtually unlimited. With an APC 

15 x 8E the Kaos becomes a rocket, but maximum, in-flight 

peaks rise to 62 – 63A (right up against the maximum surge 
current limit). Over the course of a typical flight, average 
current may still be around 30A, but could be as high as 

40A if flown aggressively. The 15 x 8 is still a viable propeller 

choice, but due to the higher current spikes during full-
throttle application proper throttle management must be 
used so as not to overheat the motor.

With either prop, typical flight time may be as low as 4 

minutes or over 8 minutes depending on how aggressive 
and active you are with the throttle – more power means 
shorter flight times.

In any case, use a flight timer initially set to a conservative 
time (4 minutes for example). When the timer sounds, land. 
Resting (unloaded) voltage should not be below 3.75V/cell. 
When you charge the battery note how much capacity it took 
to recharge (indicating how much was used for the flight). 
Strive to use no more than 80% of the battery’s capacity. 

Adjust your timer according to the voltage and capacity 

used for the flight.

CAUTION:

 

Never run the motor on the ground for more 

than a few seconds. Otherwise, you may overload the 
motor, battery or ESC.

NOTE:

 The recommended servos consume approximately 

5 mAh per minute during an average flight. For a typical 

7-minute flight that would be approximately 35mAh per 

flight. With the recommended 2S 1100 mAh LiFe battery, 
you should be able to get over 10 flights between charges 
and still use less than half the battery capacity. Keep your 
own notes and records to find out how many flights you 
can get between charges.
