Speed Control:

This is a Transistorised DC system. As the trigger is pulled, the DC voltage to the car progressively rises to increase the speed of the motor.

Brake Control:

This is a Transistorised DC braking system. A single rotary control sets the braking strength and has a built-in hold circuit to release the brakes once the car has slowed to a speed relative to the amount of brake you have selected. The useful feature of this design is that motor drives the brake circuit in such a way that the faster the car is going, the harder the brakes are applied. As the car slows, the brakes are gradually released to give very balanced and predictable control. The brake and hold remain balanced to leave you free to race confidently.

Sensitivity Control:

This adjusts the trigger wiper sensitivity to enable you to set the controller feel for any car or track condition.

The small, square blue pre-set potentiometer, on the board at the end of the trigger contact segments, allows adjustment of the sensitivity range. Turn anticlockwise to decrease sensitivity.

Adjustable Spring Tension:

Easy adjustment with a cross head screwdriver to set the spring tension. You will see the little tensioner cam moving to pre-tension the spring.

Trigger Single and Double Finger Sections:

The controller is supplied with the single finger section fitted and the double finger option in a little packet to fit as required.

TruSpeed Slot Car Controllers - for serious racers

Designed and built in the UK by Steve Hills.

TruSpeed was established by Steve Hills because he could not find a slot car controller with settings that could be customised to suit his driving style. Steve is a very keen slot car racer, and as he raced different slot cars, on different tracks, he realised that a one-size-fits-all slot car controller was not good enough.

Steve worked for many years in the audio industry and is the designer of the modern Bozak range of products.
He applied this design skill to his passion for slot car racing and TruSpeed was born.

Maintenance Tips:

Once you feel a scratchy movement of the wiper fingers over the contacts, or can hear squeaking then it is advisable to clean them. Apply a small amount of switch cleaner/lubricant, lighter fluid, or something similar, onto a cotton bud and, through the air flow slots in the casing, gently wipe over the contacts on the board.

Be sure not to bend the cable at the exit of the handle. The wiring will break from metal fatigue after a while and cause intermittent operation. Wind the cable into a gentle coil as shown in the images and it will last.
