Connecting the Battery
The MSC-12L comes pre-wired with an 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.
Adjusting the Transmitter
1. Set the “throttle reversing” switch to the NORMAL position.
2. Set the “throttle trim” to the CENTER position.
Speed Control Programming
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 button to toggle between LiPo and NiMH/NiCd modes. After the button
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 cutoff).
C. Green light indicates NiMH/NiCd mode.
One-Touch Endpoint Setup
Note:
Please be sure to set 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!
Selecting Speed Controller Modes
To change modes on your MSC-12L hold the setup button for over 5 seconds
while in neutral. Once you find desired mode, simply release the button 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
*NoTiCE:
Crawler mode is for use in rock crawling vehicles only. Do not use
this mode with your 1/10 XXX-SCB.Doing so may damage the
vehicle.
