    👍 getting into brushed motor lots of great learning

      Thanks Paul, I know a few things to make me dangerous but I'm still learning too.. It's a lost art, tuning a brushed motor. These days, You can't really buy a good new motor and used ones are just that, used (some are great but cost upwards of 400 bucks).. I just bought what I thought was an 8 Turn Reedy Ti motor but ended up with just a Ti can, the endbell and Armature were Trinity... It's not a good mix, and by that I mean it wasn't practice to use an Epic arm in a Yokomo can, same for the endbell.... The arm was a 12x3, the can was marked 8T.. My fault for not seeing the endbell before buying it but it does run, just not as fast as I wanted it to.

    Hey Bob, that was a nice test, I was hoping to have performed the same demonstration on a standard 540 silver can some months ago, but due to the unique bearing size of the standard silver can, I couldn’t locate the correct bearing size(s). 😊 I could see that from you rpm the bushings and bearing where around the same 28400 rpm, but I could hear the bearings sounded a lot smoother and the motor tested seemed to be able to spin up more efficiently. I would suspect that this would equate to a higher speed when the motors are under load on the RC car 🤔🧐 it will be interesting to see the motor on your Holiday Buggy and seem how it performs under real world driving conditions. 😊😊best wishes to you and the family 😎😉😊

      Hey John, Thanks man... I remember you trying that, thing is, those sealed cans use an odd size bushing(s) and the hard part is taking them apart and getting them back together, I think the older cans were thicker and had better crimps on the endbell. As I said then, when I tried it, I realized it wasn't worth the effort.

    Well mate, that proves the bearings help it spin a little faster on "no load". But I would suspect that it will make even more difference to the revs when under load as there should be less friction - that's my guess anyways!

      Only time will tell my friend (I still don't have the motor in the buggy). I really need to get my butt back out and do more runs... I have a few to still do.. The Yaris, Bush Pig, Fox, Brushless Clod (issue still not fixed), DT-02 speed run, Holiday Buggy & The Blockhead Motors Wild One with the Tamiya TZ motor installed.

      @@MarkBryanRC It's my lack of enthusiasm holding me back, I'm finding RC not as fun to run like I did when I was younger (late 40's to early 50's)... I'm not dealing with the crap your dealing with...

    Cool video Bob!
    I've upgraded all 6 of my superstock motors to bearings...... and, what a real cnut of a job it is getting them seated might I add!!
    They just want to stick to the magnets inside the can..... and boy those end bells are as tight as a nuns chuff when it comes to pushing them home! 😂
    But, I've gained 1mph in speed on most models that I tested..... they also seem to stop the motors getting quite as hot, and those superstocks do like to heat up!
    A highly recommend procedure if you ask me.
    I like to take my brushed motors apart for a clean and check every winter, which is the perfect opportunity to add the bearings!

      You can use a Tamiya 4-way wrench (cross-wrench, spanner) to help seat the bearing into the can, if need be, cut the 2 small "arms" off so they don't smack the magnets (I find it helps line up everything with them in place). As for the endbell, man, on the 3 I did, they all popped out (the bushings) really easy and the bearings went in like a well lube..... Never mind all that, it was easy... For maintenance on brushed motors, I still follow the old racing rules, clean, lube and new brushes after 5 to 10 runs (If I was racings, new brushes after every 3 runs). True the comm after every 20 to 30 runs (every 5 runs in a race motor). My problem is, It's hard to find RC motor cleaner in the States or really good/race quality brushes (high silver content) or even the good spec class brushes (hard compound/economy brushes). So much more to brushed motors no time to type it... Bottom line, a clean motor with new (newer) brushes is a happy motor.... Heat is the enemy. motor temps over 200 degrees F (93.3 C) or higher will cook a brushed motor.. I try to keep mine under 180 degrees F if I can.. Some people they can run a brushed motor pack after pack (Nimh, Lipo, whatever) like they would a brushless motor then bitch cause the motor burned out or stopped working.. These types of people just wanna plug in a pack and go, too lazy to do any "leg" work to maintain a motor or lack the brains to do so.

      Very wise words mate..... and totally agree with everything that you said!
      Our generation that grew up with this tech are fairly clued up..... I have quite decent knowledge of brushed stuff from racing back in the late eighties /early nineties, and learned how to look after my gear properly (money was tight back then!)
      It's the whole brushless thing that I haven't got a clue about..... and very rarely dabble in that area! 😂
      Cheers for the top tips regarding the box wrench..... I will definitely try that next time buddy!
      Nice one mate! 👍 👍 👍 😊

    I have a TZ in my TT02 it was just 20 USD in Japan pretty cheap. I don't think foe the 500rpm I would bother doing the bearings though it would last longer I'm sure.

      Hey Joe, it's an old APS Racing Dyno-Charger.. Like most old cool things, it's no longer made (like Epic, Orion, Yokomo, Top Brushed motors).

      I really couldn't tell... However, it should be a bit more efficient.
