POWERPACK / ECU Main Unit
Because the
POWERPACK / ECU
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 internal pump motor can produce electrical noise when operating, it is highly
recommended that the installation of this equipment be done as far as possible from the R/C
receiver. Keep the power cables at the minimum possible length and avoid installing the
antenna(s) near them.
3.2 Pump/Starter Battery
The
POWERPACK / ECU
needs for its operation two different power supplies. The first is
taken from the radio receiver through the throttle servo connection and the second is the
(POWERPACK / ECU)
battery that supplies power to the pump, starter and ceramic igniter.
Reversing the polarity of the POWERPACK / ECU battery will cause the destruction of
the POWERPACK / ECU semiconductors.
The
POWERPACK / ECU
battery does not need an on/off switch in the airframe since the
POWERPACK / ECU
has an internal electronic switch, which disconnects it when the power
to the receiver is switched off.
Note:
Charge your batteries properly and make sure your packs are no less than 4 flights
low. You can go more if you wish, but it’s a good habit to re-charge after every third flight.
3.3 Radio Receiver
The
POWERPACK / ECU
is connected to the radio receiver like a standard throttle servo,
inserted in the channel for the throttle, receiving the information of the throttle control pulses
and the receiver battery supply.
3.4 Fuel Pump Line out
The next generation fuel pumps inside the POWERPACK have an improved input (suction
line) design utilizing a 6mm barbed fitting. Connect necessary length of 6mm tube in the
suction side of the pump from the fuel supply, and the 4mm output line to the turbine. Place
the manual on/off valve between the air trap and the POWERPAC. We recommend placing
the MANUAL valve where it can be closed easily in case of an emergency.
NOTE:
It is recommended to safety tie all barbed fittings with 0.5 mm (.020”) safety wire.
