Hi all

I'm familiar with the Magneto engine kill switch setup (G26) but not on the EI type.

Though I can off the power supply switch to the ignition unit, what about the remote kill as Servo actuated?

Do you create a circuit on the grounding wire? With the GP kill switch unit, how is the setup go? Between the black color ground wire?

My Zenoah g20 EI does not explain such!

Thanks!

Could you speak up a little, Ralph? I'm getting hard of hearing...<G>

Save time, weight, and the possibility of having radio interference by getting a Smart-fly or electrodynamics optical ignition kill unit. Using a servo-activated switch does you no good if you lose Rx power in the air. You would obviously be in a world of trouble already if that happened, but it would be worse if the engine is still running full boar at the time of impact. with these optical units, the ignition will shut off if power to the rx is lost. They also have a light you can plug into them that will come on whenever the ignition is on, so you know for sure, on the ground that your ignition is on or off - not so with a servo-activated switck. By the way, these units weigh a whopping 0.6 ounces...

Simple= use a servo operated switch with a push rod to shut off the power,
Also simple= use a servo to close choke.. If you fly pcm use failsafe presets to do either one.
Best=use optical switch

Or use an Opto-switch between battery and EI.
This has the added advantage, that the engine is killed if battery power to the receiver fails.

Hi.
I don't have a gas engine (yet), but to me it seems strange that this functionality is not built into the ignition unit.
It would be very easy for the manufacturer to incorporate an additional plug for the receiver, to connect into a spare channel, operated by a dedicated kill-switch on the transmitter. Fail safe functionalities could also be incorporated. Added cost would (well, should) be virtually zero.

Hi Magne,
You can't run a hardwire from the ignition to the reciever due to RF noise. You need to have about 1/3 meter(1 foot) separation.
