What are these and how do they work.
A freind of mine got rid of all is R/C air stuff and these were in the mix. Neither of us know what they are or what they do. While we have some speculation I would like to see if anyone knows before I start tinkering with them.

RE: What are these and how do they work.
I'd guess that it's a mixer of some sort (e.g. elevon mixer). It appears to have some adjustments, probably for centering, reversing, mix type, etc. Unless someone can ID that PC board, you might just have to hook it up to a receiver and a couple servos and play around with it to see what it does...

It says "(C) 2001..." on the PC board... what's the name after that?

Might be a failsafe. IC Senses loss of input from the reciever and puts the control surface into a predetermined position.

RE: What are these and how do they work.
These LMDs (Little Magic Devices) were popular a few years ago before computer radios were common.
Basically; they are a mixer to emulate flapperons and/or elevons.
Unless you really need them for a current model that you want to control with a 10 year old radio...I'd recommend that you scrap them.

I don't know why anyone hasn't seen this already. Those are clearly bi-polar, reversing switcher semi-conductive, reactor thingy-ma-bobs (sorry for all the technical jargon). If I were you I'd make darn sure nobody from the government saw those. Actually it probably doesn't matter because they give off such a high level of radioactive isotopes that nearly everyone in the northern hemisphere has probably detected them already.....Turkish spy stuff is so passe.

After the "(C) 2001" it has "PME" on it...

This is obviously the model II version as it incorporates negative jitter reversed polarity tank circuits. The negative and reversed polarity cancelles each other out, hence, no jitter. Pretty smart!

Perhaps the PME stands for PrecisionMicroElectronics: http://www.pme-rc.com/ ?

PrecisionMicroElectronics does have some cool stuff... I like the rocket engine ignition module for rocket powered gliders or RATO!
