Great Planes SS80 Brushless ESC 80A - GPMM1860 - Manual

ElectriFly’s Silver Series line of ESCs are designed for no-frill, quick
plug-and-play convenience for controlling brushless motors. All
feature the Safe-Start function, which prevents accidental propeller
rotation until the ESC is deliberately “armed”. NiCd, NiMH, and LiPo
compatibility is also included, plus a high-power battery eliminator
circuit (BEC). A thermal protection system will automatically stop
motor rotation if ESC temperatures reach extreme levels, and a brake
function can be manually switched on or off. Radio, battery, and
motor connectors are all factory installed.
IMPORTANT PRECAUTIONS
Read and follow these precautions carefully before use.
• NEVER use more than the specified voltage on the ESCs input.
• ALWAYS mount the ESC in a position where air can freely flow
across it during operation.
• ALWAYS turn on the transmitter before connecting the battery to
the ESC.
• ALWAYS disconnect the battery from the ESC when not in use.
• ALWAYS remove the propeller from the motor when working on
the model!
• ALWAYS observe that a propeller might unexpectedly rotate
anytime that power is applied to the ESC, which could cause severe
injury! Never get near the propeller!!
• Make sure the input battery is fully charged before connecting to
the ESC, so the low voltage cutoff feature can function properly.
• Do not attempt to use Silver Series ESC with brushed motors.
• Do not allow water, moisture or any foreign material onto the ESCs
PC board.
• Use heat-shrink tubing to insulate any bare wires between the
motor battery and ESC, and from the ESC to the motor to prevent a
short circuit.
• Allow the ESC to cool before touching and between flights.
• Keep out of reach of children.
• ElectriFly is not responsible for incidental damage or personal
injury as a result of misuse of this product.
BATTERY ELIMINATOR CIRCUIT (BEC)
The built-in Battery Eliminator Circuit allows the ESC’s battery to also
supply power to the receiver and servos, eliminating the need for a
separate receiver battery. Refer to the specification chart at the end of
this manual for the BEC current ratings for each Silver Series ESC.
It’s very IMPORTANT to understand that BEC circuits are rated
to handle only a certain amount of current, power, and heat. If such
limits are exceeded the ESC might reset itself, automatically returning
throttle control back to minimum! This could happen if too many
servos are used or if using servos which draw high current (high
torque or digital servos), and is especially important to know when
flying extreme 3D maneuvers which require all servos to be
activated very rapidly at the same time. If a BEC reset occurs, only
the throttle channel will be affected – control of all other surfaces will
not be interrupted. By simply “re-arming” the throttle channel (see
“STEP 6 - ESC SETUP”) while in flight you should be able to re-gain
throttle control very quickly.
It might be hard to determine exactly how much current is being
demanded through the BEC circuit. As a general guide, refer to the
chart below to determine approximately how many servos can be used
with the different size Silver Series ESCs. Remember, this is only an
approximation! More extreme setups (with very high powered digital
servos, for example) will be more demanding on the BEC circuit.

Do not use BEC
If you experience unwanted throttle resets, it may be necessary to (a)
reduce the number of servos in your aircraft, (b) use less powerful
servos, (c) disable the ESC’s built-in BEC circuit (described below),
and instead power the receiver and servos with a separate receiver
battery, or (d) disable the ESC’s built-in BEC circuit, and power the
receiver with a stand-alone BEC circuit that is rated for high power.
