Would those be for the ignition battery?

Yes for ign. batt

Use a fiber optic kill between ignition battery and motor. Use a switch on your transmitter and you have a fool proof engine kill.

R/C Foolish

Is the ignition battery same as the receiver battery?? also is it necessary to have a kill switch on the ignition battery wire?cant we just close the throttle to shut down the engine

The ignition battery is a seperate battery that must be kept at least 12" away from the reciever. You always want at least 2 methods of killing a gas engine. I use 3 - choke on servo, radio transmitter kill, and fiber optic. That way if something happens to throttle servo you have a backup and a manual choke doesn't do you any good up in the air. If this is your first gasser, there are a lot of things to learn. What type of plane and which motor are you using. You only need an ignition battery if the motor has an electronic ignition. If the motor has a magneto like the Zenoah's then there is no battery.

R/C Foolish

Mustafa,

You will need to have a 4.8 volt battery for the ignition. This will be a separate battery from that used for the receiver. The battery will need to be plugged into a switch which will take care of the off and on function for the engine. the erason that the two wires, red and black, are left open ended is because the engine manufacturer has no idea as to what type of switch you may want to use. Whatever switch and plug type that you decide on, just add the mating end of a plag to the wires from the engine.

Shutting down the engine with the throttle trim is just fine, and has been done this way since gassers were first used for R/C. You should have enough throttle trim to idle down to a safe taxi speed anyway, so why not enough to shut it off, right? The switch is a failsafe method of shutting down the engine and to keep the battery for the ignition from being drained. Some people feel the need to have 3, 4, and more methods of shutting down the engine. I haven't yet understood why.

I'm saying this "tongue in cheek" but if you become truly afraid of the plane in flight and can't get the engine to shut down, just aim it at the ground. I guarantee that the engine will shortly stop.

Mustafa, call me and I will tell you how to fix it.
