I got this ESC with the JRX Pro I traded some stufffor.
I dismissed it,at first-I didn't even bother to test it.
Got around to testing it today,though and it works very,very well!
Trouble is-I don't know the motor limit,or what the adjustment pots are there for,I mean I could take a guess,but I don't want to damage it.
I saw an old Tekin that looked similar,but no cigar.
Apologies for the poor photo-I'll snap some better ones of in the morning.
Can anyone ID this?

Oh-I popped the case open and found on the circuit board was 'MC9' 'S155B'.
I got rid of the horrible wiring in the above photo,too.
One of my pet peeves...That's what you get for working for an electrician for 4 years

Futaba MC9?

Thanks,Joey! Mr. King to the rescue,again
Looks like it is an old Futaba number.Lucky I didn't strap in my 'Destructo' 8x1 Revolution motor,with a 17 turn limit,huh?

Futaba MC116 ??
