1.2 General Description
The ECOTRIM is designed for a 3 1/8 in or a 2 1/4 in standard instrument hole. It is a very
simple control head but yet powerful. It comprises two red knobs to easily trim your aircraft.
You can trim your pitch and aileron, but if you add a third servo then YAW can also be
included. Aileron and Yaw share the same knob, just press for 3 seconds to toggle from one to
the other.
Trim position is shown on the instrument by two arrays of LEDs (automatic night diming).
Aileron and Yaw share the same array.
Take-off and landing, just click on the red knob and trims will immediately center.
The joystick (black ball) is on the top left-hand corner of the controller. If you click on it, your
airplane will now be flying using a joystick, just like a big yet fly-by-wire control. This will allow
you to fly your airplane in case of a mechanical linkage disconnect.
A prewired harness is available but you can also make your own. Add four extra wires and you
can connect your trim system to your pilot and/or copilot stick or yoke to use your hat switch
for trimming. Aileron hat switch can be shared with Yaw.
Connector is a DB15 at the rear of the unit. Pins are compatible with the SuperECO and iLevil
autopilots for easy upgrades.
An RS-232 port is provided for future interface with SuperECO and iLevil autopilots as well as
for synchronizing two ECOTRIMs.
If you want to make your own trims, you will need RC analog airplane servos. These PWM
signals are compatible with our ECOTRIM.
