I have recently acquired a Top Flite GSP-40 ARF and I need some help connecting a Great Planes kill switch into my OS GT 55 ignition system. Neither the OS nor the Great Planes instructions are very clear on how to do this. There are only two wires(one black and one red) to connect to the system, but I don't have a clue as to where and how to make the connections. If you can help me out on this I would greatly appreciate a diagram if at all possible. This ismy first venture into the world of gas power andconecting the kill switch isthe last step needed to complete my assembly.

Thanks,
Bill

Is this the one you are talking about?

If so, that is for a magneto engine, not an electronic ignition engine like the OS 55 GT.

You need something like this:

The switch could be made to work but the mode would have to be changed from the normally open mode as it comes from Great Planes to a normally closed mode.

The switch and the technology are from many years ago. On the old magneto gasoline engines, like the US 41 that this switch was intended for, if you ground out the ignition, the engine would quit. Very few people use magneto ignitions anymore.

The switches can be re-wired to open the battery supply circuit for a modern day ignition system but it is still an old fashioned way to do the job.
