Period Correct ESC

[torey3]

Hi guys, new member here with a Late Edinger that I pulled out of 25 year storage. New battery and works mostly great. I am conisder upgrading the mechanical speed control with a period correct ESC with reverse. What performance gains can expect from this and what models would you recommend? I am running a modern non-lipo battery and a trinity monster horsepower engine.
Thanks

If your gonna run it id go with a modern esc.THe vintage stuff hard to find and cost more than a newer esc.If was for a shelfer only i could see putting a T1x or T1 AND T4 IM NO EXPERT on vintage but should be around that time period i think.don

As far as vintage with reverse, which limits you to the more unreliable sort, you'd be looking for a futaba mc112b or better yet a mc111b. Those were hugely popular. For reverse there were also some Airtronics, KO, and JR but they would be harder to find and more expensive. Look for speed controls that are shaped like a servo, with ears to bolt them in. They will almost always be reversing and era correct

I purchased a new entry level speed controller recommended from Hobby Town; however it did not work. The sales man said that it my vintage KO Pro servos and remote were to slow for it. I then purchased what was advertised and appeared a brand new futaba mc 112b speed controller, but could not get it to power up with my KO Pro controller. I don't know if the speed controller is bad or if it is not compatable with the wiring in the KO servo? Any suggestions?
Thanks

Ko should use standard pin layout, as opposed to Airtronics. What are the color codes on the ko servo? I want to say they use a blue in there somewhere. On the futaba it should be white, red, black. The servo is channel one, the speed control channel two. Those futaba esc don't have a switch so when you plug in the battery it should make the servo jitter.

Actually.... the older KO stuff had a different pin-out to the regular stuff (Futaba et al). While Futaba would be sig - pos - neg (white - red - black), the KO stuff, like older Sanwa stuff, had a pin-out of sig - neg - pos (blue - black - red).

If your receiver is blue - black - red, all you'll need to do is swap the pins around in the lead coming from the Futaba ESC, and everything should power up fine.

Let us know if this makes sense (or not!).

I thought I vaguely remembered early ko being different but I couldn't find pics to back it up. All the pics were more like jr/futaba

Just be careful- check colors twice before powering up. You'll never get the smoke back in the receiver

Ever have one of those "DOH!" Moments? I could have probably just went to the shop and opened the box I totally forgot I had this ko
