Throttle curves
The ECU controls the RPM in linear way, i.e., at half stick position the engine turn at half of the
rotor RPM range. However, jet engines develop thrust in exponential way, meaning half RPM
means approximately ¼ of thrust.
On small engines with a high idle to full power rpm ratio, or in a high drag/low power planes, of-
ten only the last 1/3 of the throttle stick produce significant thrust, with the low half stick travel
being not much used. Although with current digital TX the pilot can modify the throttle curve to
suit needs, three throttle curves have been added to simplify the setup for most of the installations.
These curves are selected under the RADIO menu:
FULL EXPO: Means thrust is linear to RPM, it is the default setting. Thrust develops exponentially,
and it is the recommended curve for high thrust/weight ratio planes, as it ease the control in low
power used during taxi.
LINEAR: Mean that the thrust develop linearly with the throttle setting.
Could cause difficult taxi, as it would be difficult to fine adjust the
power at low setting.
HALF EXPO: An intermediate setting between the other two modes

Throttle curves can be changed while the engine is running, so you can leave the throttle at a giv-
en position and switch between the curves to see the difference.
Acceleration and deceleration settings.
In the “RUN” menu it is possible to change the acceleration and deceleration times. The engine is
supplied and tested from factory ready to use and usually these settings should be correct for
