Can anyone identify the box in the two accompanying photos? There are four
relays, more than a dozen silicon diodes, and a power resistor. I can hazard a
guess or two but would like to hear from someone who recognizes the box and
knows what it is.

My neighbor cut it out of a Speed Canard he's rebuilding. The operative words
are "cut out"; I do not know to what it was connected.

It's a relay box.

Did I win? What's the prize?

Don't recognize the box, but the 1st thing that comes to mind would be a

selective controller (and high current protection for switches) for trim
functions. There are commercial products that allow 2 sets of trim
switches, and can give '1st push' priority for control, or
pilot-priority for control.

It's a 2-channel relay deck. One pair is used for (pitch?) trim (labeled on
wire). The second may be for speed brakes or nose gear... not sure.
The power resistor may be used to limit stall current (landing gear) or the
speed of the trim motor.

This is a guess, but the wiring shows one wire set as 'trim'.

That's my guess too . . .

I think you're all correct. A relay deck/trim controller makes sense especially
in light of the Speed Canard having electric trim switches on both sticks. Good
job -- apparently this was easy (for everyone except me Smile

Alas, there is no prize but I will have the satisfaction of telling my neighbor
he needs to repair the cut wires and re-install it <g>.

Thank you all.
