Default Latch Magnets from junk motors

I recently fried a motor. Being a Yankee I salvaged as many parts as I could. I was about to dispose of the can (it was an out-runner) when it grabbed my allen wrench with considerable force. "Hey", methinks, these would make great latch magnets. So I salvaged 24 (?) of them by prying them loose from the case. They can be cut or simply broken to the size you need. And they are a HOAL cheaper than Radio Shack!

I do the same with junk motors tear out the magnets. I have the usual small screw driver set. I take a magnet and place it on the screw driver presto no more dropped screws. Of course I mainly save them for hatches.

Been doing that for ages !

Also salvage old control wires ... tubes etc.

Even broken canopy's ... amazing what a piece out of one can do to repair another even on a completely different plane !

Leads of fried ESC's .. batterys .... servos ....

There's loads of gear with a bit of lateral thinking ...

Yeah, I've got a bunch of magnets pulled from high powered magnetic actuators from work. These things will pull over 400 pounds on a one inch thick steel block. With these things you do have to watch your fingers. (Don't ask! My finger didn't stop bleeding for 7 hours.)

If you ever want to BUY some of this stuff, get out your credit card and take a look:

Or if you want to amputate some fingers:

It's not a good idea cut or break Neodymium magnets. Materials in them are toxic. Be careful sanding them to increase glue hold. You don't want to get into the material inside or make toxic dust.
