NOTE: While in the programming mode, no power is applied to
the motor.
Battery Selection: When the ESC is powered on, the LED will be
flashing for 2 seconds to indicate the Selected Battery Type.
During this time the user can press the key to toggle between
LiPo and NiMH/NiCd modes. After the key has been pressed
(battery type selected), the LED will flash for 2 more seconds.
A. Turn on ESC and push button once within 2 seconds, push
again to toggle between modes.
B. Red light indicates LiPo mode (with 6 volt cut-off)
C. Green light indicates NiMH/NiCd mode
One Touch Endpoint Setup
NOTE: Please be sure to set all throttle trim settings to neutral
before performing an endpoint setup.
A. Hold button and turn on ESC until the Red/Green light
comes on. Once on, release button.
B. Pull trigger to full throttle position until the green light goes
from flashing to solid. Once solid, your forward endpoint is
now set.
C. To set reverse endpoint, push the trigger into the full
reverse position until the flashing red light turns solid. At this
point your reverse/brake endpoint is now set.
D. Return trigger to neutral setting. The green light will now
be solid and you are ready to go!
To change modes on your MSC-12L hold the set up key for
over 5 seconds while in neutral. Once you find desired mode,
simply release the key and you are ready for action.
Forward/Reverse mode—Solid Green LED
Forward Only mode—Fast Flashing Green LED
Practice mode—Slow Flashing Green LED
Crawler mode*—Solid Green and Red LED
*NOTE: Crawler mode is for use in rock crawling vehicles only.
Do not use this mode with other vehicles. Doing so may
damage the vehicle.

The MSC-12L comes pre-wired with a EC3 connector. Use battery
packs from 4-cell (4.8-volt) to 7-cell (8.4-volt) sub-C size battery
packs or with 2S LiPo packs (7.4-volt).
1. Be sure the on/off switch is in the “off” position.
2. Connect a fully charged battery pack to the speed control’s
battery connector.
1. Set the “throttle reversing” switch to the NORMAL position.
2. Set the “throttle trim” to the CENTER position.
Steering servo operates but the motor does not run
Symptom
Solution
Programming is not complete. Reprogram the ESC by following the programming instructions.
Speed control connected to receiver incorrectly.
Motor defective. Test motor independently, repair or replace as needed.
Low batteries. Charge as needed.
Overload Protection enabled. Check motor and connections.
Steering and motor do not function
Receiver wired incorrectly. Check polarity and orientation of controlplugs.
Batteries discharged. Recharge or replace.
Full speed not attainable
Transmitter adjusted improperly.
ESC programmed incorrectly. Reprogram.
Motor slows but will not stop
Throttle trim may be set improperly.
ESC program does not match transmitter. Reprogram ESC.
Reduced radio range/Interference
Motor capacitors broken/missing. Repair or replace.
Motor noise. Move receiver further away from ESC, motor and wiring
Transmitter batteries low. Replace batteries.
