Repairing vintage escs can be a great learning experience. Half the battle is tracing out the circuits and part number research for compatible replacements. I test functionality with a voltage supply that has adjustable current output. I wire a small 380 motor to check operation since it has low current consumption.
Another very useful thing for troubleshooting is a good optical scope. Many failed components can be found using the scope and looking for signs of part stress or overheating. I use something similar to this and have pretty good success repairing the EBay "working" escs.

Another must have is a decent fluke digital multimeter and basic electronic troubleshooting knowledge. Look up the part numbers with google search and find the data sheets for the components. They really help to reverse engineer the circuits.
For those interested on how this little gem is programmed or what the manual looks like or simply for archival value here are the photos of the manual that I took:
Found in my craigslist score ( which is where most of my stuff is coming from )
From what I have gleaned from various forums this is either the most brilliant ESC in the history of RC ~OR~ one of the biggest wastes of silicon ever made....

Best esc iver ever owned. I beat masami using this with an over geared over worked on for better balance and performance Mr M. I used three scotkey (i think thats the right name) diodes attached and set on 100 amps continuous. Once you set the esc...
I got this Tekin receiver with a buggy a while ago. Before getting it i never even knew Tekin made receivers :lol: Can anyone tell me if these were any good in their day, and roughly when they were being sold?

The Tekin FM receiver was released in 1992
Tekin AM receiver
I´m not sure for AM but for FM you have to use the right crystals otherwise the system doesn´t work. I know some transmitters are using internal frequency multiplication so in reality...
I need a brushed ESC and am interested in FX-R ESC because it is compact.
wonder if it is suitable for a 1/10 EP buggy or not.
Anybody has experience with it?

By the way, I noticed that you're from Alberta. 10 years ago, I stayed in Edmonton for four months.
That is a great city, I felt safe and comfortable staying there. :D
Thanks, yeah...Edmonton is not too stabby. :lol: You're pretty much building a...
Hey all,anyone here point me in the direction or share with me the manual,instructions for the tekin M star esc.. Or point me to another tekin that may share the same setup calibration procedure as the m star.. Thanks everyone :mrgreen:
