Ignition Switches

       Remove this ad - become a site supporter!
OK I just bought a ZDZ40 and it didn't come with an Ignition Switch.

Can anyone recomend one that has both a manual switch and one controlled by radio so I can kill the engine by remote?

Thanx in advance!

There are a few ways to "kill" this problem, heh heh....

(these are some I have tried)

(NOTE: the battery which runs the ignition module MUST have an on off switch mounted somewhere near the cowling, I am assuming you know that and are asking about a second RC operated way to kill the engine)

#1 - simple method, use the throttle trim to fully close the carb and on most engines this will instantly kill them (or within a second) but not ALL will... my ZDZ60 will tick over for 10 or so seconds, whereas my 3 Brisson's and my other few gas engines all died immediately.

#2 - use a push button momentary switch acitvated by a length of golden rod, ie, the servo pushes the switch down via the control rod, and this opens or closes the circuit (place in series obviously with the slider switch on the fuse/cowling) I use this on my AC-1 (servo holds down the switch to make contact - I have it on my retract switch on the tranny to kill the engine)

#3 - use an optically isolated electronic switch like the one from electrodynamics. I have this on my Extra. I also use the retract switch to kill the engine.

What if you put the choke on a servo and use that to kill the engine?

Gasser ignition switch

On my ZDZ's 160, i use 3 ways of killing the engine.

1) Throttle trim.
2) Ignition switch on fuse side.
3) Choke on separate servo controlled on a potentiometer on the radio.

This way, you always have 3 ways to shut off the engine. Also, if you happen to have a throttle servo problem, or linkage, you can use the choke servo as a throttle and control your engine with it and maybe save your plane, or avoid flying your plane at full throttle for 10 minutes after loosing throttle control. I have seen it happen and it works.
