I did it, only now when I run the car it makes a high pitch sound and it won’t go in reverse. What is the mesh set up for it? Do I put a piece of paper just like with the mini? Help please 🙏🏼

If the mesh is adjustable, press the gears together, then very lightly snug the motor screws. Pull the motor away from the spur ever so slightly until you JUST see the spur rotate while the pinion stays still. If you can just SEE a little play, you should be good. For the small stuff, you don't really need any play in it. You just don't want any pressure there. So just make sure the gears aren't pressed together. A sheet of paper (.003" or so) would be way too much play for such a small gear pitch. You're looking for more like .0005" play lol.

What do you mean it won't go in reverse? Did it before? Did you reset the ESC? I don't have a Micro B, but it is technically a race vehicle, and the ESC may be set to forward/brake only. Look in your manual for the ESC settings, if it has any. Set it to Forward/Brake/Reverse if possible.

With Forward/Brake/Reverse, pressing the trigger forward to hit the brakes won't go into reverse until you return the trigger to zero and push it forward again. That's to keep you from going forward, then immediately hitting reverse, which would likely tear the drivetrain to pieces pretty quick.

I think the gears were way too tight and there was binding, I used a paper and it worked but it was a regular piece of paper but I pressed the gears just enough. I’ll adjust it again with a receipt paper later on. Also the heatsink was too wide for it to fit the motor properly. I might have to grind it a bit.
 
Out of the box my micro b and t were both setup f/b/r. Haven’t had to mess with mesh yet, good info @WickedFog

Do like I said and just adjust it by eye. You would have to use tracing paper, and even that would be too thick. Just get your finger in there and push the spur back and forth. Just get it to where you have the tiniest amount of play you can get rocking the gears back and forth, and that will be perfectly fine.

I don't know what the pitch is, but if it's like .8 mod or lower, which I bet it is, don't use paper. Paper is fine for bigger gear pitches, like 32p. But I don't even like using it on 48p mesh, and I actually don't use it on anything. All by eye.

For the tiny stuff... there isn't anything you're going to find thin enough to get proper mesh. As the gear pitch decreases, so does that tolerance where the mesh is correct. So just do it by eye mayne 👁

Do what @WickedFog has suggested. Don't use the receipt.

I think it was a mod .5 judging from the hot racing replacement gears.

Sounds about right. With gearing that small, even if you tighten the motor and the gears are ever so slightly touching each other, that would be fine. Get out the old man "I can't see chit" headset and set just enough play between the gears to slide a gnat's wing in there and you are golden lol.
