I have unearthed my PowerGrip 2000 thumb controller and wondered if anyone knows if its on a par with the modern units, or if anyone knows of any mods for this controller that would get it up to speed.
It has a braking control and a sensitivity control plus a max / min brake switch.
Anyone out there with knowledge of this hand control ?

Electronic thumb operated controllers are rare. I have references to several that were sold in the mid '60s and also the one offered by Slot Car Distributors. I have never heard of yours and a Google search only turned up this thread. For a start you might give all of the contacts and pots a shot of contact cleaner to be sure it is working well, then just hook up and see what happens. Experiment with the adjustments. Possibly the range of adjustments will not match your requirements. If the controller feels good in your hand and seems to have fairly robust construction you may be able to modify it to suit your needs.

Lots of types of electronic thumb controllers were made in smallish quantities in the UK. (I doubt many found their way to the USA)
Many used minor variations on the same circuit and still work well.
What sort of transistor does it use? (the part number is usually marked on it).

Here is a very early Transistor controller that was made and sold here in Australia in about 1966, I have two of them. They have no brakes and use what looks like a hand wound resistor in the handle.

You think Pulsed width controllers are new?
Here is a pic of a board for one published in an old Model cars magazine.

Hi,

I wanted to post this earlier, but couldn't find it.

Anyhow a few people prefer the thumb control.
