Engine installation: Electrical connections
Connect the power lead of the battery to the male Multiplex socket.
PLEASE: DOUBLE CHECK THE BATTERY POLARITY BEFORE CONNECTING IT TO
THE ENGINE.
A reverse polarity connection will immediately damage the electronic components on both
the ecu and the engine. Recommended battery is a LiPo of 7,4V and at least 2000mAh /15C.
Optionally is possible to use an A123 battery of 9,9V, although the engine is happier with
7,4V. 3s Lipo is not supported.
Battery should be connected directly, DO NOT
use switches (electronic or mechanical),
electronic regulators, diodes, voltage regulators, etc. Multiple battery operation is possible,
but at least one battery must be directly connected to the ecu.
Connect the throttle channel from your receiver to the socket in the ecu labeled “throttle”
and the data terminal to the socket “Terminal”. Maximum voltage at throttle input port is 10V.
Connect the fuel pump to the ecu. Check the colors. If connector is placed reversed, the
pump will run backwards.
Connect the 3 wire powerbus to the engine and to the ecu. This lead can be extended.
Although Data signal can be used with lead lengths up to 10 meters, the power looses on
power wires (red and black) will increase with length, so thicker cooper section must be used
on long lengths. Up to 1 meter, 1mm2 section is OK. If you make your own extension lead,
DOUBLE CHECK THE POLARITY
. You will damage the electronics inside the engine if
polarity is reversed.
