IMPORTANT NOTES
1. The electric starter depicted in this manual has a Battery Eliminator Circuit
(BEC). The BEC circuit is rated at 1 Amp. Do not use this circuit to power the
receiver of your airplane. The BEC cannot handle more than three regular sized
servos. If you do so the BEC will fail with possible catastrophic consequences for
your airplane. Turn off the micro switch on the electronic soft start module to
disconnect the BEC circuit.
2. In order to avoid interference from the gas engine, you must use an electric
noise suppressant on the electric starter’s wiring that comes back from the electric
motor. Radio Shack® offers two types of electrical noise suppressants. The
simplest noise suppressant is called “Snap Together Ferrite Choke” and its part
number is 273-105. The other type Radio Shack offers is the “10 Amp Noise
Filter”. Its part number is 27-051.
3. The starter’s remote On/Off switch should always be assigned to a spring-
loaded switch on your transmitter. It is important that you do this for safety
reasons. The spring loaded switch will always be in the “Off” position when the
transmitter is turned on and the starter motor will always stop spinning when you
release the switch after the engine is started.
