Sounds like reverse polarity to me, cant think of anything else that would do that. Double check that you soldered the wires to your ESC the right way around.

It was a 2nd hand car - so i didn't do the orginial soldering. Thanks - i'll take a look.

Are the GTB 4 Cell ESC's protected from reverse polarity? (HOPE SO!)

Just ordered a set - appreciate the tip. I've been struggling with foam tires.

What type of track do you use those on? Running blacks on our carpet track is like putting on ice skates without knowing how to skate. CRC Low Greys in the rear seem to be the best compromise for durability and traction with CRC purples up front. Need a little more steering on a cold day and lilacs work well.

No, most likely you damaged a fet or two, from your post it sounds like the magic smoke did'nt release but I suspect that it will soon.

Default gearing choices

Hey Guys
I'm running a 17.5 epic duo for the first time in my 12R5.1 getting ready for
my first visit to the SNOWBIRDS. Looking for some advice on a starting spur
and pinion size for that size track, I'll be running 44 rears, any advice would greatly be appreciated....
Thanks

Depends on which ESC you have! When I downloaded the new Tekin RS software, I dropped 8 teeth on my pinion, after increasing my spur by 12 teeth! (was 72/44, now 84/36)! That's on a 100 x 60 track.
