Yokomo ESC Question

[catcando6]

Hey guys,

Long time lurker and reader, first time poster ...

I picked up a new Yokomo BL Pro esc for, what I thought, was a screaming deal. Everything was hooked up and ready to turn so hot laps. It kinda works ... some times it has trouble getting started, like it's bound up. Give the car a little push and it'll go for a little then dies (like the power was turned off.). Sometimes it works OK and you can modulate the throttle from real low to full and then stops. Sometimes it "cogs" to a stop. I did a bunch of part and car swapping and the esc is definitely the culprit. I swapped batteries, cars, motors, sensor cable, ran just the motor with no spur gear and the issue followed the esc. Very reproducible. Is this a problem with the esc software version?

Thanks!
Brian

no software is needed i used my old one for 2 runs and did the exact same thing! what happens is the motherboard is shorting out inside the speedo...sorry to tell you but there is no repairing it.

well that's just awful news! I've been able to tune the parameters to make it work 90% of the time, but I can already see a setup for failure. Qualify P1 in a big race and have the car not move at the start ... guess it wasn't that great a deal after all!

Thanks for the reply!
