If memory serves me correctly it was an entry level unit from years ago (at least 12-13). I'm sure that i had one at some point. CAn't remember any more than that.

MattW is right, it was an entry level speedo prone to frying FET's if you go too wild on the motor wind. From memory it came out in about 1990. It was aimed at the Off road market as there wasn't anything else at that time. You need to remember that back then we were running 1700 mah cells and a 14 turn motor was considered pretty wild.
With today's cells and motors you might be advised to stick to a Stock Motor if you want to run the speedo and keep it working!!!

Thanks guys for your help.
I like remanessing.
As I started out we were just switching to 1400's.
One of my first esc's was an Accoms AT-1.
But I never did own a Futaba speedo. As for setup I quess it probably would be kinde like the AT-1 but then I 've to think waaayyy back...

Simple set-up, justplug everything in, turn it all on (with car setting on blocks so the wheels don't touch the ground) Adjust the nuetral pot until the motor is at neutral, then pull full throttle and adjust the full throttle or current lpot until the motor is spinning as fast as possible.

I would stay stock or machine wound 20 turn (street spec, traxxas stinger, mambuchi 540, maybe even Reedy 19T that comes with associated RTR cars) Don't overgear and the speedo should serve you well for a basher or mild racer.....

Impact thanks a lot.
It'll probably just serve me as a fun controller.
After all it's allmost an oldtimer.

Yo Pizza,
If you want to see it in black and white, the manual is still available in PDF on the futaba website. www.futaba.com.

Make sure to NOT attach the battery to the motor wires, it's easy to get backwards and WILL INSTANTLY FRY IT!

I know, I did it to mine.
