Decided to switch over to Tekin and give them a shot. Hooked it up correctly, turned it on and the dreaded smoke puff. Capacitor was smoking hot. Yes I tried a different receiver, motor, sensor wire, battery is fully charged. Everything worked with the other speed control. Checked the wiring at least a million times just to be sure. Everything is right but the smoke!

Just the cap that smoked ?-sounds like something was touching it shouldn't have- not saying-just saying. I got lucky once, wasnt watching , and solder the B+, B- backwards, and smoked the cap..That speedo still working for me today... Hope you get it figured out..

Nothing touched. Even tried cutting the cap off to see if it would setup and no luck.

Hmm, I would call Tekin, and get an RA#, their Customer Service is the one of the best--they will stand behind the product if its a bad speedo-which for an RS PRO-is not usually an issue--good luck, sorry to hear you had a problem..

did you solder the cap on wrong?

The blue is NEGATIVE SIDE!

I know how the cap goes on. All wiring was correct.

Contact Randy Pike on the Tekin RS/RS Pro ESC thread in the electric offraod section, he'll be sure to help you out.

Did you get an RA# for service yet? If not, let me know.

SEEE-----now that's customer service-----

Mark... If you're in a spot for the JConcepts race let me know... I've got at least 1 spare RS Pro this weekend you could use for the event.
