Was looking at a little extra security on my bird, thought about changing out the Master toggle switch to some sort of key switch.
Here's what I have... Here's what I'm looking for (not this cheap Amazon chinese special, a real milspec one). Any ideas? Searches turn up nothing so far. I do put a throttle lock on the bird when I'm parked away on the hamburger flights or when I'm not immediately around it. I know it's not a cure all but it's a simple thing to do if I can find the right key switch. Don't want to go through the effort of the mag/master switch, it'll make a bigger hole....

Get a cobra motorcycle lock and wrap it around the prop.

Locking the master will only prevent them from using the radio. Flip on the mags and hand prop it.

Agreed. Just another layer. Anyone can cut the p-leads also.

Just install an Aircraft approved Keyed Switch !
Every position will work except the Start position !
If You want one, I have one for sale!

I meant to say Aircraft Keyed Mag. Switch !
