Random cut outs ... Ideas needed !

[szymanski2oo1]

Hi all, need some ideas..

I ran my desc410 today with a skyrc toro 150amp esc and trinity monster power 5.5 sensored motor ... Randomly on occasion if I crashed and stopped still the truck would not move ... Steering was fine ... And when pushing throttle back and forth it looked a bit like it was rocking like it was trying to do something... To get it going all it took was a nudge forward from another truck and it was back to normal ... It didn't happen every time I stopped still ... Just randomly ... The Esc is new ( 4 meetings old) and motor is second hand ( looks tidy but don't really know how much use its had) ...
I'm going to try change sensor lead , motor wires are soldered well , just wondered if anyone knows if this is a problem indicative of a particular issue ?
Cheers
Jon

had the same issue on my desc410 with a trackstar 150a esc, which i beleive is the same as the skyrc, it was cogging so bad it would not get going without a nudge, tried 2 brand new motors, 1 5.5t and a 6.5t but same on both, i went down a few teeth on the pinion which helped but could never cure it fully

Ah Cogging ! I thiught with sensored motors that wasn't supposed to happen?although That sounds like the right term for what's happening... I was thinking of trying to strip the motor down give it a clean in case that will help..?

I had the same problem in my 1/8 electric running a hobbywing 150a speedo with a absima 2100 motor running it sensored it would cog and not run properly but soon as I ran it sensorless had no issues.

Just try it without the sensor lead and see how it goes.

Ah cheers will give it a try, Is it ok to just un plug the sensor lead? Or do I need to change the esc settings etc ?

Just remove sensor lead you shouldn't have to adjust any settings on the speedo as it should detect that there's no lead attached and run in sensor less
Mode.

When I was having problems with the hobbywing I looked for all the info I could find and found that it would work with some motors like nosram, lrp, and think reedy and heard Tekin worked with it as well.

But I think with the absima motor it wasn't getting the right signals sent from the speedo to tell it what to do.
