Please read right through these operating instructions before attempting to use the speed con-
troller for the first time.
Specification, BL-ESC 30 A controller:
Continuous current:
30 A
Peak current:
40 A (< 10 sec.)
BEC mode:
linear
BEC output:
5 V / 2 A
Cell-count, LiPo:
2 - 4
Cell-count, NiMH / NC:
5 - 12
Low-voltage guard:
yes
Dimensions (controller):
23 x 43 x 6 mm
Weight:
25 g
Caution: the speed controller is not protected against reversed polarity! Connecting the
battery to the controller with reversed polarity will instantly ruin the controller.
If you wish to use a separate receiver battery instead of the BEC system,
locate the receiver connector attached to the speed controller, withdraw the
contact on the red wire, and insulate the bare end to avoid short-circuits.
VERY IMPORTANT:
since different transmitters feature different throttle channel values, we
urgently recommend that you use the “throttle range set-up function” to set the throttle range.
Please read the section entitled “Setting the full-throttle and stop positions” later in these instruc-
tions.
Using the speed controller for the first time:
Pull the throttle stick fully back (towards you), then switch the transmitter on.
Connect the flight battery to the speed controller.
You will hear one of the following sequences, depending on the battery type:
LiPo: the controller emits two audio sequences:
1. “***” if a 3S LiPo pack is detected. The cell-count is automatically detected (the number
of beeps indicates the number of cells).
2. “*” if the brake is switched on.
“**” if the brake is switched off.
NiMH / NC: the controller emits one audio sequence:
In this case you will hear only “*” or “**” to indicate brake switched on or off.
The speed controller is ready for use.
Move the throttle stick forward: motor starts.
Setting the full-throttle and stop positions (if the transmitter is new, the throttle range
should always be re-set):
Switch the transmitter on, and move the throttle stick fully forward (away from you).
Connect the flight battery to the speed controller.
The controller emits the sequence “--, --”. Move the throttle stick to the desired Stop position within
the period of the four repeated beeps.
The controller emits “--” to indicate it has registered the Stop position. It now emits the audio
sequence according to the battery type. The speed controller is ready for use.
Protective functions
1. Overheating guard: if the temperature of the speed controller rises above 110°C, the unit red-
uces the output voltage.
2. Throttle signal failure guard: if the throttle signal is absent for a period of one second, the speed
controller reduces the output voltage. If the signal fails again for a period of two seconds, the
speed controller switches off the output voltage completely.
Description of function
1.
Full-throttle / Stop position
2.
Brake setting:
brake ON / brake OFF;
default setting = brake OFF
3.
Battery type:
Li-xx (Li-Ion or Li-Poly) / Ni-xx (NiMH or NC);
default setting: Li-xx.
4.
Low-voltage cut-off:
low / medium / high;
default setting: medium
1) In the case of Li-xx batteries the cell-count is detected automatically. Cut-off voltage low
/ medium high at:
2.8 V / 3.0 V / 3.2 V. E.g.: medium cut-off voltage setting with three LiPo cells: cut-off
voltage is 3 x 3 = 9 V.
2) NiMH / NC batteries: cut-off voltage low / medium / high at: 50% / 60% / 65% of the initial
voltage. E.g: with a six-cell NiMH battery the fully-charged voltage is 1.44 x 6 = 8.64 V; if
the cut-off voltage is set to low, the cut-off voltage is: 8.64 x 50% = 4.32 V.
5.
Default setting:
resets the values to the default settings (see Programming).
6. Timing:
automatic / low / high;
default setting = automatic
Automatic timing can safely be selected for most motors. For high performance we recom-
mend low timing for two-pole motors (inrunners) and high timing for motors with six or more
poles.
Carry out a bench check before flying the model.
7.
Start-up / Power-on mode:
ultra-soft / soft / normal;
default setting = soft
Normal is suitable for fixed-wing model aircraft.
The start-up speed when set to soft / ultra-soft is fairly slow: one second (soft start), 1.5
seconds (ultra-soft start), timed from start-up to full-throttle. The ultra-soft setting is particu-
larly useful for models with geared motors.
8.
RPM Control, Heli Mode
Default setting: off
Selecting Governor mode disables the brake. The low-voltage cut-off is set to reduced
power.
9.
Direction of motor rotation:
the direction of rotation of the motor can be reversed electro-
nically (see Programming).
