Hi
I recently converted my .46 trainer from nitro to electric
Motor turnigy G46 with Red Brick 100Amps ESC
It was working fine, when suddenly the motor started jittering so I completely dismantled the motor
To check out the wiring and magnets but found nothing wrong next I replaced the ESC and the motor was working fine. It looks like a problem with one of the three connectors to the motor so I resoldered it, but the problem persists I have checked the ESC for any broken connections
Any help as how to fix it would be welcome

Regards

You said it works fine when you replace the ESC.  So it works with one ESC, but NOT with the one you have been using originally ?  That would indicate a problem somewhere on the original ESC (including its wires/connectors).

What type of connectors are you using between the motor and ESC... bullet connectors ?

Hi Anwar
I am using 4mm bullet connectors ,I have resoldered them again just to eliminate the possibility
Of loose connection , still cannot get to the problem.

Do you have the male side or female side of the bullet connectors on the ESC ?  And do you feel that bullet connects are a proper/tight fit when connected together ?

Does it make difference? I've seen everyone soldering male on motors and female on ESCs. But I did the other way. Is there any problem?

Typically, the males are on the motor, and females on the ESCs. Now if that is the case (male on motor), then the remote possibility that the male bullets have shrunk and lost proper connectivity would not explain why another ESC worked.

But if the male is on the ESC, then the behavior seen MAY be due to those male bullets being deformed.

There are lots of other possibilities, like the wires on the ESC having broken strands, the ESC itself being bad etc.  So far, if we read all this right, we know that the motor seems to be OK, as it works with another ESC.  Good thing that he has multiple large capacity ESCs to substitute and test.

I didn't think that far... I felt it was easier to solder the thin motor wires to females... Thanks,

Hi

I have male connectors on the motor and female connectors on the ESC so the problem of the male connectors being deformed is eliminated as motor is working with the other ESC.

Bit off topic but i saw in one of the video that power source (ie. ESC in this case) should be connected to female connectors always. They gave a simple example, just think what would had happnd if all electrical points in our house had male plugs instead of female socket

But there is always choices of every individuals

I think the case you said is different. We shouldn't have males at the houses's plug-points because they protrude outwards and we may come in cmtact with them, accidentally. This, I opine, has nothing to do with our case.
