I was digging around in an old R/C parts box and found these.:D:D:rolleyes:

It really makes you stop and think about how far this hobbys come!

I'm new in the hobby and have never seen. Looks like a variable resistor using a servo? Would this be a early version of a ESC? What the heck is it?:confused:

My slot car controllers have those, they are heat sinks right?

good collection of old escs ... I think i still have a couple like that somewhere in a box

Good ole speed controller. Wasn't there then a big resistor (for braking maybe?) that was in the circuit with that somewhere? I remember the resistor getting hot, I burned a couple of them up.

Your absolutely correct Mario, in its day it was a high tech ESC, The orange one has an additional wiper on it to give a more positive brake. The green set up was the simlpest form. Its how we ran our throttles in the early race cars. If you wanted reverse you set a micro switch behind the brake so the wiper would switch it. A pain to set up some times since radios did not have end point adjustments (no computer radios).

My slot car controllers have those, they are heat sinks right?

Bricknick, This idea comes from slotcar racing, instead of holding it in your hand and using the trigger to move the wiper accross the resistor we used a servo. You've probably seen a slot car controller with a heat sink sticking out the top, that would be the orange set up. The orange one has an extra barrel with with an aluminum heat sink through it.

I was actually looking for old servos, I want to do a 360 servo conversion, I haven't found a tutorial on how to do one and I'm sure what I'm doing since I've never done one. I really didn't want to butcher a new servo. So I'll use these and put the throttle barrels back in the box!

Sure is amazing, how technology has developed. Even more amazing that you can still find mechanical 3 step speed controls in some kits, from some manufacturers. Along with bushings, instead of ball bearings.

funny i got two in my bits box. don't even know where i got them from . thats old school.
i just rember the nice fires that would come from them if you over amped them with a to big of a motor

your are right. thats what they where back in the day tamiya gave you them up to about 2000 i would say
