10+ year old JETI JES20 controller reprogram?
 
I am getting back into flying and my Jeti JES20 speed controller appears to have deveolped a mind of its own. Local hobby store owner said the unit can be reprogrammed? Can anyone offer any suggestions as to how to do this. I don't have the manual any longer. There appears to be a set screw for adjustment on the top of the unit.
Thanks.

They are on Face Books, maybe you can get some information from them there, take a picture of your ESC so they can see it for an ID

I had a 10 year old unit JES18. The only programming was brake on - off.
It did not have a set screw.
I seriously doubt you could do more with it.
It won't know a lipo from a brick so unless you are going to go with OLD (and decrepit) NiXX batteries that will be another issue.

You can pick up decent ESC's so cheap these days that IMHO its probably not worth bothering with it.

Some of the older Jeti ESCs set LVC as a % of initial voltage and you could select from high, med or low %

IIRC, these were LiPo capable by selecting the high % (lowest drop in voltage) and ensuring you did not plug in a pack that wasn't full charged. These date from 8 to 10 yrs ago. I have an Opti 60 that is that old and is just fine for liPo. (used a programming card)

So many assorted Jeti controllers out there... without knowing the specs for the one you have, best we can do is guess.
