Impulse 31

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.
