Well, I did learn that the Tamiya 101 ESC does not have reverse polarity protection... but then I also discovered that it is an easy fix. The circuit board on this giant ESC is so old-skool that even a talentless solder-man like me can fix it...

Someone else at my track had it blow in exactly the same spot.

Thanks for sharing, eventually by default TEU-101BK came with Tamiya plug. I got one for my 1st Tamiya car. So there is no way you can short. Unless if you replaced it with bananas & plugged wrongly.

one time in the rush to get my car on the track I plugged the bananna plugs in wrong on my lipo. i turned it on and smoke billoed from esc. there goes the speedo. In addition to the the wires got so hot the solder melted and dripped onto my hand before i even realised wat i had done
that hurt!!
this was when i used the original orion 3200 carbon. battery still works great today.

It still comes to the point where there is still no short protection for ESC likewise mentioned.

One time i was on the driver's stand of a local parking lot track and its low enough to the ground so you can sit on it before you put your cars down to race. So before my race, i was sitting there, car in hand, 3pk in the other, and i was ready to race.
The guy next to me must have been a little behind, becuase he threw his body on the car, turned his radio on, and in a hurry plugged the battery and esc leads toghether. Much to his demise, they where backwards.
Orange smoke filled the touring car's body and started pouring out the bottom and body post holes. The look on his face was sad and hilarious at the same time, priceless, you may say.
I'm just glad something like that hasn't happened to me. (knock on wood...)

I hooked up my GTB backwards for a second yesterday. It made a big spark and I immediately knew what was wrong. I reversed the plugs and it worked fine. I had this happen with a Tekin 411P many years ago and it blew out the brakes. The brakes still work fine in the GTB...

I've blown up 2.
First one back in 2006, wookie was at the race when I did it and was gracious enough to give me a replacement on the spot for free.
Second time happened a month ago. Wires for the power were soldered onto the board for a GTB instead of using the default plugs (not sure why this one had it this way)... Anyways... Negative power lead that goes to Receiver came undone and shorted out on the positive. Doesn't work any longer. Still need to get this Speedo into Novak for replacement.

reverse polarity protection on esc is possible, but this feature will kill a little bit of performance. this is a no go for any high performance competition esc.
it may be small, but it will be there...and that will be a turn-off for many users who are looking to extract every bit of performance...
