Great Planes C-7 Nano Brushed ESC - GPMM2005 - Manual (Page 2)

solder to flow through the wire. This whole process should only take
a couple of seconds. Make sure the soldering iron is not held on the
bare wire too long, otherwise the insulation will start to shrink.
C. When properly tinned, the end of the wires should be completely
covered with a light coat of solder.
5. Follow the instructions included with your replacement plugs for
proper installation. WARNING: Be sure to observe proper polarities.
Also, make certain that solid physical and electrical connections are
made with solder joints. Failure to do so can jeopardize the ESC,
and other components.
Adjusting the transmitter is critical for proper ESC operation. The
transmitter throttle adjustments should be set as follows:
1. If your transmitter has servo travel adjustment (on some transmitters
this is may be called ATV, EPA or ATL, see the instructions included
with your transmitter for proper adjustment), set the travel adjustment
for the throttle channel to 100% or full travel.
2. Set the throttle trim and sub trim on your transmitter to neutral or
zero. Most non-computer transmitters do not have sub trim. The
throttle trim on nearly all transmitters is adjusted by the lever next
to the throttle stick. This lever should be centered.
3. If you are using a Futaba transmitter, set the throttle reversing switch
on the transmitter to reverse. On Hitec, Airtronics and JR transmitters,
set the throttle reversing switch to normal. If you have a different
brand of transmitter, begin by setting the reversing switch to normal.
Before you begin this setup, remove the propeller from the motor.
Then plug the ESC into the throttle channel on the receiver and adjust
the transmitter.
BATTERY SETUP MODE
With the battery unplugged from the ESC, position the ESC with the
label facing up. Connect the jumper on the end of the ESC as shown
below for the type of battery being used.
ESC OPERATION
1. Switch on the transmitter.
2. Move the throttle stick to the brake position (towards you).
3. Connect the battery to the ESC. The motor will beep 3 times.
4. Move the throttle stick to full power (away from you). The motor will
beep 5 times.
5. Move the throttle stick back to the brake position.
6. The ESC is now ready to operate.
IMPORTANT: If the speed control does not operate properly after
following the above set-up procedure, switch the throttle reversing switch
on transmitter and repeat the speed control set-up.
As a safety precaution to prevent the motor from starting when the
battery is first connected to the ESC, you will need to move the throttle
to full and off every time the ESC is switched on.
Because electric motors generate electrical noise it is critical to range
test the airplane, with the motor on, before flying. With the antenna
collapsed and a helper holding the airplane, operate the flight controls
while walking away from the airplane. You should be able to get
approximately 75' to 100' away before losing control of the airplane.
Next, check the range with the motor running at half throttle. The
range should be close to the range you got with the motor off. If it is
not, you may need to move the receiver, receiver antenna servo leads
or speed control to a different location.
Problem: Motor and receiver do not work.
1. Make sure motor battery is charged.
2. The plug between motor battery and ESC may not be making contact.
3. Check that the ESC plug is correctly plugged into the receiver.
4. Unplug the ESC from the receiver and plug a receiver battery into
the receiver. Does the radio work now? If it does, the problem may
be the ESC and requires servicing.
Problem: The ESC runs but cannot be controlled.
1. Make sure the ESC is plugged into the correct slot in the receiver.
2. Check that the transmitter is adjusted properly.
SPEED CONTROL WORKS (BUT OTHER PROBLEMS EXIST)
Problem: Receiver glitches or stutters while motor is running.
1. The motor capacitors are not installed correctly or have broken.
2. Receiver is mounted too close to the ESC.
3. The receiver antenna is routed too close to the motor battery, ESC
or wires.
4. The motor battery/ESC plugs do not fit tightly.
Problem: Motor quits after only a few minutes of running.
1. The prop on the motor may be too large, causing high current draw
and overheating the speed control. The thermal cutoff is switching
the motor off.
2. The motor may be damaged (bent shaft, tight bearing or shorted
winding) causing high current draw.
3. The ESC may need more cooling air flowing over it.
Problem: Motor runs backwards.
1. The ESC is wired to the motor backwards.
SERVICE PROCEDURES:
Please Note: ESC’s that operate normally when received will be
charged a minimum service fee and return shipping charges. Before
sending your ESC in for service, it is important that you review the
Troubleshooting Guide on this instruction sheet. The ESC may appear to
have failed when other problems exist in the system–such as a defective
transmitter, receiver or servo, or incorrect adjustments/installation.
• Hobby dealers are not authorized to replace ESCs thought to
be defective.
• Do not cut the input wires or switch harness of the ESC before
sending it for service. A fee will be charged for cut wires which must
be replaced for testing.
Great Planes warrants this product to be free from defects in materials and workmanship
for a period of 180 days from the date of purchase. During that period, we will repair or
replace, at our option, any product that does not meet these standards. You will be
required to provide proof of purchase date (receipt or invoice). If, during the warranty
period, your ESC shows defects caused by abuse, misuse, or accident, it will be repaired
or replaced at our option, at a service charge not greater than 50% of the current retail list
price. Be sure to include your daytime telephone number in case we need to contact you
about your repair. This warranty does not cover components worn by use, application of
reverse voltage, cross connections, poor installation, subjection of components to foreign
materials, any alterations to wires, or tampering. In no case shall our liability exceed the
original cost of the product. Your warranty is voided if:
• You apply reverse voltage to the ESC by connecting the motor battery pack backwards
or plugging the motor wires into the motor battery pack.
• You allow any wires to become frayed which could cause a short.
• You use more than 8 cells (1.2 volts per cell) in the motor battery pack.
• You tamper with any of the electronic components.
• You allow water, moisture, or any other foreign material onto the PC board.
Under no circumstances will the purchaser be entitled to consequential or incidental
damages. This warranty gives you specific legal rights, and you may also have other rights
which vary from state to state. If you attempt to disassemble or repair this unit
yourself it may void the warranty.
For service to your ElectriFly C-7 Nano and C-12 Micro ESC, either in or out of warranty,
send it post paid and insured to:
