Some of the first 13.5 motors didn't have the larger bearing. If your motor is newer is should have the larger bearing. If you measure the bearing I'm sure we can figure out which one you have.

If you got an early motor with the ss bearing,Novak will get you the proper kit to upgrade it, they did for me. My son and I run 007's he rolls out at 40, mine is at 38. In my experience you have a verible sweet spot just as in a brushed motor. I run one in my 12th scale as well and it is also slightly different. We went to 104 spur gears to accomadate a larger pinion gear. If my son's car is geared the same as mine, I pull him four cars on a long straight. and out of the corners as well. With his rollout taller than mine the cars pull more equal.
We are running the same batteries from the same matcher with almost the same numbers(his actually being a little better).just wanted to share our experience on this

Thanks thats some good comparison. What size track? Carpet or asphalt?
You might try switching motors to see if its in the speedos.
It would be nice to zero in on the sweet spot, and know if it might be the speedo? We had a similar discussion last week.

Actually its the same batteries, motor, speedo, servo and car. Just different setups and different drivers. Hmm, the last one must be why I beat you so much Had to throw it in there.

But rollout, I have been struggling to find that perfect rollout for the 13.5. Since I have gotten the setup I have been consistently 1-2 tenths of a second off of my co27's. Honestly it didn't matter, I tried everything from 33-38mm, lap times were the same, and the car just never felt fast enough, to put it colorfully it just felt flat. Finally Friday night I put a 40 pinion with the 104 spur and 57mm tires and wow, I beat my best qualifying time with a brushed motor by 3 seconds . I never wanted to gear that high, I mean we run a small track, 40'x60', with my co27's I ran an incredibly low rollout, 23-24mm. The only thing I can suggest is to experiment, they all have a different sweet spot for your driving ability, mine just happens to be somewhere around 40.5mm.

So this one will work on the older 13.5. and you don't have to replace both bearings. I can see the diameter difference. Looks to be closer to the bonded ones. I might try that in a 5800. The one I'm buying used, still has the small bearings.
