7.2 Gas Mode (Manual Throttle, Mode 2)
Mode 2 is characterized by complete throttle
control with longer spool up times compared to
fixed wing applications. This qualifies the mode for
pilots who choose to fly without governor. In mode
2 RPM control is completely dependent on the
pilot. Mode 2 requires programming a gas curve to
the sender. Please refer to the manual of your
sender how to program a gas curve.

7.3 Combination Mode (Mode 3)
The new combination mode is characterized by
mixed operation of gas mode (manual throttle) and
governor. Via PROGDISC (HELI JIVE Card –
Programming – Transition Point – Percentage
[Defalut 50%]) a percentage of throttle way can be
set. Until this percentage the HELI JIVE operates
under gas mode (gas curve of sender). Above the
set percentage the ESC operates first in a
transition phase to finally switch to governor
control. This allows to fly different control
characteristics (Idle1/Idele2): at low RPM in gas
mode (Idle1) and at high RPM in governor (Idle2).
Mode 3 is optimal for F3C applications.
Idle1 requires an individual gas curve. Please make
sure that the highest point of the gas curve is below
the transition point. When switching to Idle2 the
ESC operates in governor.
Please make sure that the percentage value
of the gas curve is not exceeding the value
of the transition point. It is recommendable
to use the ATV function of the sender. If this
is activated, transition point and gas curve
value can coincide.
7.4 Heli Mode (Mode 4)
In mode 4 the ESC operates with active RPM
control. This means, that the motor RPM will be
kept constant. Changes in load and falling battery
voltage will be compensated, as long as motor and
battery capacity allow. It is not necessary to use a
TX mixer to stabilize RPM. RPM control works only,
if the ESC is installed in the helicopter. Operation
under no load may result in a jerking ESC. Due to
the adjustable spool up time (8-12 seconds) the
ESC can increase the motor RPM in soft start. As
soon as the needed RPM rate is reached the ESC
switches to governor. KONTRONIK recommends a
value of 65-70% of full throttle setting set on TX for
optimal governor control.
The HELI JIVE RPM control is adjusted
automatically to the application during the first start
of the motor after connecting the battery. It is
recommended to set 0° pitch to ensure relatively
constant RPM during each flight. To start the motor
push the throttle stick towards full throttle. The
HELI JIVE will smoothly increase the motor RPM in
a few seconds. As soon as the designated RPM is
reached the JIVE switches over to close loop
speed. The closer the throttle position is to full
throttle, the higher is the designated motor RPM.
Use flat curves in the TX for IDLE modes.
The following protection functions are active in Heli
mode:
If there is no valid TX signal for more than 4
seconds, the ESC switches the motor off.
At excess temperature, the ESC lowers the
power slowly (30 seconds) to zero
At under voltage cut-off the ESC lowers the
power slowly (30 seconds) to zero. No further
operation
possible
until
new
battery
is
connected.
If LiPo-Mode is active, detection of under voltage
cut off also lowers powers motor slowly. Without
LiPo Mode under voltage disconnection is disabled.
Restart is possible after disconnecting and
reconnecting the battery.
7.5 Heli Mode with fixed governor control
(Mode 5)
In mode 5 the ESC operates with active RPM
control. This means, that the motor RPM will be
kept constant. Changes in load and falling battery
voltage will be compensated, as long as motor and
battery capacity allow. It is not necessary to use a
TX mixer to stabilize RPM. RPM control works only,
if the ESC is installed in the helicopter. In mode 5
all relevant parameters are programmed only once
at the first start of the motor. Also the relation
between RPM setting at the sender and rotor RPM
is stored. Different batteries lead therefore to
identical RPM. However, differences in the cell
count of batteries can only be compensated to a
certain extend. It is not allowed to program mode 5
with a four cell battery and take the same RPM for
a six cell battery. After changing the set-up (motor,
rotor blades etc.) mode 5 must be reprogrammed in
order to guarantee a stable and fast RPM control.
Due to the adjustable spool up time (8-12 seconds)
the ESC can increase the motor RPM in soft start.
As soon as the needed RPM rate is reached the
ESC
switches
to
governor.
KONTRONIK
recommends a value of 65-70% of full throttle
setting set on sender for optimal governor control.
To start the motor push the throttle towards full
throttle. The HELI JIVE will smoothly increase the
motor RPM within the selected spool up time. As
soon as the designated RPM is reached the JIVE
