I dug this up while foraging through my crawl space, looking for a couple tool racks.

I'm not sure if I ever posted this before, but this is what a scratchbuilt controller looks like.

Yours, Mike?

 

When was that controller built/used?

I built it in probably early 2002.

I won three Nats Championships with it, in 2002 and 2003.

Among its features are:

1/4" Lexan sheet frame/handle.
Solid brass bar trigger.
Telescoping, spring-loaded wiper button (basically a miniature shock absorber).
Paint job by me.

It stood for Koford 24 band.

I think at the the time, 15 bands was the max any commercial controller had.

The switch block was made from K&S brass strip, Plastruct tubing, a couple Koford 3/32" axles, and diaplane material.

It's interesting that Group 7 racers went from resistor controllers to electronic and back to resistors again (simplicity and easy to repair).

 

Cheers.

That was the theory.

I was seeing too many electronic controller failures (probably from hooking up wrong).

You really couldn't blow this thing.

Mike, 

 

I may have missed something in the evolution of the resistor controller, but where do all those wires go?

To the three connected resistors coming out of the side of the box.

It's just an external resistor controller, but with three resistors instead of one.

I never kept track.

When people used to ask, I would guess 80 hours, plus or minus 30 hours.

When I graduated from plastic track to racing on wood, approx 88/89 I had no commercial type stuff and little money. I crafted this for club racing using materials I had except for the ohmite 4 ohm resistor. Let's see if anyone can identify the origin of the handle! 20170223_115450.jpg

Is the grip something to do with archery?

I'm guessing ski pole handle. 

 

It's amazing someone hasn't reverse engineered that amazing controller and is selling them out of eastern Europe or China.

Geez! It doesn't seem that long ago that we were buying Parma controllers for the handle and frame, then making

a switch block from brass bar and phenolic sheet so we could wire a huge ceramic resister to it. Still have a couple

of those, both home made and from JK.

Lol.

They are to hang the controller.

Some sort of plywood "clip"/ joiner.

Probably a Simpson Strong-Tie item.

Coincidently, they had their company Christmas party by me, a few years back.

Here is my scratch built controller - built around 1990 - 5mm " lexan sheet, 5 layers glued together around handle. parma trigger and brake/full power contacts.

 

When I built it I figured that there was so much time spent customizing a Parma that I may as well just buy a trigger and contacts and start from scratch. The lexan came from a windscreen off my brothers racing car.

David I like the idea of the simple controller handle with all the controls on the box, but the box is way to complicated. Just give me sensitivity and brake controls.
