I think its a T1 or T4 speedo. Here's a link to the manual in PDF format on Team Novak website: T1 & T4

Hope this helps.

Talking From an old Novak manual....

Plug controller into battery pack and leave motor unplugged.....

Neutral pot is on the left and speed adjustment is on the right (make sure they are both in the full clockwise position).

Turn on transmitter and speed control.

Slowly rotate the the neutral pot counter clockwise. The led will decrease in brightness to full off and then switch to full on. This is the neutral position.

Advancing transmitter throttle will make the LED go off and stay off. If the led goes of then slowly gets brighter, flip the transmitter throttle reversing switch and redo.

With the transmitter at full speed, slowly rotate the high speed pot counter clockwise on the speed control until the led switches on again. This is full speed.

Slowly release the throttle. The led should go off at about 85% full throttle.

Instructions came from the T1X but should work. Depends on the transmitter you have though. The manual shows that for most models back when it came out that throttle trim and high point adjustments should be set to max and throttle exponential to minimum. Brake exponential to minimum.

mine only had one row of fets. The instructions were pretty much the same as for the T1X which had two rows.

No LED might make it a Novak NESC4 or NESC1...I think one pot is neutral and the other *may* be power curve.

I had a NESC4 but can't remember which is which...too long ago

One pot is Neutral and one pot is full speed, first adjust the neutral pot just under the point where your tires roll forward (no reverse, just brakes), then with a voltmeter connected to the motor leads, adjust the full speed pot so that the voltage peaks just before you reach on full throttle on the radio trigger. this is a low frequency speed control, do not use a schotty diode, instead use a 47uF, 25volt electrolytic capacitor.

Yes what Scrubb said. If it doesn't set up I may have a set of instructions, but it will take some looking.

BTW, be careful as I don't know if it will handle any low turn modern motors. And unless running a srock motor it should use heatsinks that press onto the power and brake MOSFET's. Brakes are 2 that are offset and never short the brake and power MOSFET's.

Also as the battery is depleted, the steering will lock and the car will continue rolling with no control.

I used a KO Pulse checker(i think it was called) to set mine up...basically worked the same as a setup LED does now and you just clipped it onto the motor leads.

I may still have it lying around.
