Page 12: Pump/Starter Battery
I.C.S. Main Unit Because the I.C.S. is an electronic piece of equipment, the installation in the model aircraft is similar to that of the radio receiver. It has to be in an accessible location within the airframe, with limited vibration and far from the heat of the engine. Also because the pump motor uses DC power, that can produce sparks in the collector when operating, it is highly recommended that the installation of all electrical equipment be done as far as possible from the R/C receiver. -

Page 24: Radio Submenu
4.8 Radio Submenu IMPORTANT – Please Read Before programming the I.C.S. to learn your transmitter throttle settings, it is important that you clear your transmitter of all and any MIX or FAILSAFE program you might have programmed connected to the throttle channel, this can interfere with the operation of the I.C.S. - Page 25 In order to do it, move to the menu screen, press “radio” submenu and you get to the adjust screen. This first menu is only informative and it warns you of the entrance in the screens of programming of the throttle control.
- Page 26 With the I.C.S. in start mode, that is to say, just started, locating the trim and the stick at lower side the LED must be off. When raising the trim slowly, the LED must light approximately to half of the throw of the trim. From this point the I.C.S. considers that the motor must be running and below this, stopped.

- Page 32 Starting the engine with Kerostart. For kerostart engines please read Preparing the engine for running Always test the engine in a test bench before installing it into the plane, this will confirm that all system work as they should, and you will be able to learn its operation and the emergency procedures.
- Page 33 Another big difference between gas start and kero start is that the kerosene can keep burning during long time inside the engine. This situation usually happen during an aborted start, the start-up sequence is aborted by the user or automatically before the engine arrive to idle. This can cause that the kerosene inside the engine keep burning for long time, and could destroy the engine or the model.
- Page 34 Move the stick to 50% and then back to idle again. The ECU will begin the startup sequence as described below: First the internal glow plug will be energized. After 6-10 seconds, depending on the engine temperature and battery charge, the starter will be powered up to have the rotor turning at 3000 RPM.
- Page 35 IMMEDIATELY APPLY THE FIRE EXTINGUI SHE R through the intake side of the engine, never trough the exhaust. If there is a fire, but the rotor remains free to spin and the starter is OK, raise the trim and stick to the full power position this will connect the starter manually to ventilate the engine and extinguish the fire.
