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

I am not sure (We have had a few now.) I think I am going to go back to 27t Which is the same as stock silver can (I think) Hopefully this combined with heat sinks will help but it is a process of elimination like you said OCD

Back to the drawing board. The 17t died last night. It started to sound different on the previous run from the shrill "beeeeeeeeeeeeeeeeeeeeeee "of a nice motor You all know to a rough almost raspy sound for a few.minutes with loss of performance then nothing. It even had a heat sink on ! I will learn how to pull it apart tonight and have a look and put some pics up and hopefully somebody will point me right..🙄 I have ordered heat sinks with fans to try and help cool the motors as they are red hot.(hot enough to make the heat shrink glue on the wires go soft again) The ESC heat sink is only warm. Perhaps my batteries are too "punchy"? Clueless again. What batteries are people using and are they using the stock silver cans or similar.? Thanks again all.

I have just been searching through my eBay history and discovered it is actually Zap goo I used. But I have recently bought some shoo goo to repair my poly-carb body so I will let you know how I get on....

Has anybody used this taping technique? I may well give this a go with the pro-life Trenchers we had as they are really trippy and hard wearing but balloon with the updated motor.

This is incredible. What stuff tends to break most.? Is this stock with 3s Lipo? Or is it brushless?

We got some and discovered we couldn't get any traction as the rubber compound was too hard (perhaps they were old as they were second hand) But the car was uncontrollable so we switched back to the stock tires. They really are shredded now so some new ones are required....

I am leaning towards this one.. (below) as it seems slightly familiar? And the costs ring a bell. But my memory is shocking so can't guarantee this is the actual one I got. Hope this is of help!

What a beach! Good advice on the tires mate ! I may well do that and try and source better wearing tires but looking at a grass set of stock spikes as we have 2 sets of wheels for each car now (I had to get one as well built from eBay scrap cars and parts)

I've racked my brain and tried to remember. I reckon I got it off eBay but I am uncertain if it may have been from USA to UK for about £40 (including postage) The one I had came with a blue spray film? So don't know if the one on ebay above is a bit too cheap and cheerful? but £10 plus paint is worth a punt.!
