Bugged out

Perhaps this one...

Thanks Mark I connected it and it ran. I will get a meter tomorrow but it's similar to the quicrun symptoms so doesn't look promising. I'll have a search for those set ups. Anyone is welcome to throw in any comments/views/advice as I think brushed technology may well be done for me so it's back to school and start trying to get my head around the next thing...

Right ! I've set everything up for a run with my son and the ESC in one car acknowledges the battery and power on then the steering works but won't command drive... Exactly the same as the quicrun 1060 did with the silver can a couple of years ago which led us to change the ESC. How do I test the ESC to see if it's toast or not? I am on the brink of brushless now as this motor issue has gone on long enough. 😶 If it were to happen... (which is very possible now) I am looking at a goolrun combo.....

Thanks OCD I really appreciate the info I'll trim the guard as I have a spare. Messing about with these hopped up motors has been costly (could've bought 2 brushless combos by now) But it has been a learning exercise. So if this doesn't work I'm going to put some middle of the road combos on and admit defeat! (We'll see) Thanks to everyone who has commented and given tips. I wouldn't have found out half as much by myself.

Thanks! I didn't even think of that! I haven't run the car with the heat sink on yet. Does this look ok? I don't see it making a short or am I mistaken?

Without testing them both they seem the same. I have a hobbywing quick run ESC spare which I could try... The only other variable left is the batteries(I think) as I bought them off the 'Net in all my naive eagerness to get back into it after 25yrs ...😳

Rebuildable SMD 27turn motor from modelsport installed with basic heat sink. Hoping to extend the wiring on the one with a fan to help with cooling.(hopefully) I will run it in slowly before letting my lad give it the beans... Fingers crossed!

Sorry for late update! A strong repair I think. Looks cracked but is really solid.

It ran ! At slow speed(to break it in) For about 30 seconds then It slowed to a stop and felt like it was getting warm.. Stumped. Enough for one day....

Now all I have to do is put it back together ....

No I don't have the gear for that I'm guessing a multimeter will be needed? I'm skimming the com now (kind of a rough set up) and practice really The brushes have caused quite a deep wearing on the com. Then I'll put it together and lube with some fine oil and see what happens...

This is what I've found. I will clean it up and skim the come and see if that returns the motor. I don't like the colour of the turns but will give it a wash and see ...

Thanks Juggular! This is of great help. I will get some com drops before I start the repair work and keep on top of the lubrication in the future. I have got a 2nd hand lathe/com skimmer coming as I am going to use it to teach my son how to maintain and repair the motors rather than go and buy another one every few runs. I still haven't got round to having a look inside the cans yet but I have 3 motors to refurbish so will hopefully put some pics up.

So after an evening of YouTube education ... I realise that I should have broken in the motors 😫 what a rookie mistake. It's seems this may help to prolong the life of the motors. But also as we're running them hard we may well need to rebuild the motors and skim the comutator every couple of runs as is done in racing. Does anyone know where to get spares from these days?

This is the state of the brushes after aproximately 16 runs for 15mins. I will take the end bell off and have a look further
