Kill switch
I have a one third scale Sopwith Pup with a G62 in it. I just had the G62 converted to electronic ignition by RC Ignitions. I am trying to set up a kill switch that is not too noticeable or too close to the receiver. If I had a smart fly optical engine kill switch am I still required to have a secondary kill switch on the plane? I do not have a choke servo. I appreciate your help. This is my first electronic ignition.

RE: Kill switch
I assume that you are trying to adhere to IMAA rules for a kill switch. The rules read:
You need a manual kill switch.

SECTION 5.0: EMERGENCY ENGINE SHUT OFF (Kill Switch)
5.1 Magneto spark ignition engines must have a coil-grounding switch on the aircraft to stop the engine. This will also prevent accidental starting of the engine. This switch shall be readily available to both pilot and spotter/helper. This switch is to be operated manually and without the use of the Radio System.
5.2 Engines with battery powered ignition systems must have a switch to turn off the power from the battery pack to disable the engine from firing. This will also prevent accidental starting of the engine. This switch shall be readily available to both pilot and spotter/helper. This switch shall be operated manually and without the use of the Radio System.
5.3 There must also be a means to stop the engine from the transmitter. The most common method is to close the carburetor throat completely using throttle trim, however other methods are acceptable. This requirement applies to all glow/gas ignition engines regardless of size.

RE: Kill switch
Yes,
I am going to fly it at Old Rhinebeck in Sept. I just don't know what switch will work the best and not take away from the look of the plane. I originally had a ground out switch for the magneto in the cockpit before the ignition.

RE: Kill switch
The switch does not need to be mounted externally. Have a wire actuator pop out somewhere to actuate the switch. Just remember to explain to any helpers the function of the wire and how to kill the engine.

RE: Kill switch
I've been told and read that if you use 2.4ghz Radio equipment, that distance between Kill Switch and Receiver is not as important as it is with 72mhz Radio equipment? is this true? and if it is true than your Switch Placement choices increases.

RE: Kill switch
Thank you all! I have the switch mounted in a non conspicuous spot that I can still get to and is well away from the reciever. How sweet is that warthog? My friend, Rick flew those back in the 90's.
