ESC
The included ESC programming card (DYNM3821) allows
you to quickly program your Dynamite® Marine Brushless
ESC control settings.
programmable Settings
Throttle Reverse: ON or Off
Cutoff Voltage: High Cutoff or low Cutoff
High Cutoff: The Ni-MH Cutoff voltage is .9 volts per
cell and the Li-Po Cutoff is 3.3 volts per cell. High Cutoff
allows ample power in reserve after Cutoff for returning
the boat to shore.
Low Cutoff: The Ni-MH Cutoff voltage is .7 volts per
cell and the Li-Po Cutoff is 3.0 volts per cell. Low Cutoff
allows longer runtimes, but leaves less power in reserve
after Cutoff for returning the boat to shore.
Cutoff Type: Idle or Slow Down
Idle: When the Cutoff voltage is reached, the ESC will
stop delivering power to the motor.
Slow Down: When the Cutoff voltage is reached, the
ESC will drop to 50% power at full throttle.
To reset, return the throttle to neutral.
Brake: ON or Off
ON: The boat will stop immediately when the throttle is
returned to neutral.
OFF: The boat will coast to a stop.
Timing: low Timing or High Timing
Low Timing: For 2-, 4- or 6-pole inrunner motors.
Allows the longest run times.
High Timing: For 6-pole or more inrunner and outrunner
motors.
High timing increases both motor RPM and current
draw (up to 20% increase compared to low timing)
using the same battery pack and prop. Run times will be
signicantly reduced.
Only use High Timing if the temperatures of the
electronic components do not exceed 130°F (54°C) in
Low Timing mode.
Throttle Curve: linear or logarithm
Linear: The ESC delivers 60% power at half throttle and
100% power at full throttle.
Logarithm: The ESC delivers 45% power at half throttle
and 80% power at full throttle (recommended for
beginners).
using the ESC programming Card
1. Set all programming card setting switches to the
desired positions.
2. Ensure the ESC is powered OFF and disconnected
from a battery.
3. Connect the ESC receiver lead to the ESC port on the
programming card, noting proper polarity.
4. Connect a fully charged battery to the ESC or the
programming card, then power on the ESC.
5. The ESC will beep, indicating that the new
programming has been accepted.
6. After programming is completed, power OFF the
ESC, disconnect the ESC receiver lead from the
programming card and reconnect it to the throttle port
on the receiver, noting proper polarity.
7. To reprogram, power OFF the ESC and disconnect the
battery for 5 seconds, then repeat the steps above.
