Hi,

I'm in the process of intalling my first gas engine in a byron husky. I've got a great planes kill switch and upon using a meter on it i've realised it doesn't work the way i would of expected.

I've read the past topic http://www.rcuniverse.com/forum/Grea...2542721/tm.htm
and now understand the engine i killed by grounding the coil.

I'm a bit shocked as on my fuji 32B, as far as i can tell, this would mean that with no switch assy. connected, i.e straight out of the box... the ignition would be LIVE!!

Is this the case?

Thanks

Yes. But, there is no spark energy without velocity (rpm).

That's correct. That's why it's very important to install the kill switch. A gasoline engine can pop, if not actually start, any time the prop is flipped with enough speed to generate a spark.
