which and why is the prefered kill system
choke the choke or electronic kill

for electronic ignition gasser

In this country they keep saying you must have an electronic kill switch.

But almost everyone shuts the engine down also by closing the throttle all the way with the trim on the thottle channel.

Some also have radio controlled chokes in addition to the above two.

I much prefer the TX controlled choke as I can kill the engine with it, and I can also control the choke for starting without getting my fingers near the prop when the engine starts.
Here is my setup

Any of the mechanical kills certainly have their place. There are times however when that doesn't cut it. Although rare, I have seen engines and mounts come loose which made servo operated kills innefective. On one occasion, the engine came loose and everything shifted or moved forward so to speak and the mechanical linkages wouldn't stop the engine. In that or those cases I suppose electronic would have saved the day_bob

If I'm really concerned I'll ensure the throttle will kill the engine at low throttle and low throttle trim and I'll put the ignition batt on a servo operated by a switch. This way you can kill it mechanically or electrically. I usually kill the engine by turning off the batt switch.

I can kill the engine by closing the carb all the way or closing the choke. Both are from the transmitter.

I went to a microswitch activated with a servo and nyrod. The nyrod is driven by the servo and, of course, there are no worries about conducting noise down the rod.

I activate the servo with a switched TX mix off of the throttle. The throttle has to be lower than about 25% to get enough mix for a kill. This is cool in case the TX switch is ever inadvertently bumped while flying.

I can kill my gasser from the radio trim switch as well as a toggle switch located on the firewall. And if I really want to "kill" the engine, I get out my trusty Glock 22... yuk, yuk.

If I cannot get them to run right(very seldom) I kill them by parting them out or with a sledgehammer. Both works!!!!
