Remove the bearings, degrease them, spray them with a silicone dry lube and reinstall. Instant free drivetrain.

And, I"m willing to bet that the Losi and Kyosho have less drag because of the metal shielded bearings. Most other cars use rubber seals.

Big heavy straight cut gears are natually going to have more friction
than the smaller spiral cut diffs. The upside is there almost bulletproof
if you build them properly. When was the last time you saw a RC8B or
RC8T with diff problems? The trade off for the smaller lighter diffs is they
must be built properly and reshimmed as they start to wear.

The other side to this is bearings, and the choice is either to run the cheaper
1.00 bearings and live with the slightly stiff drivetrain or step up to ceramics
and keep them maintained. NO bearing is going to remain very free for long
with the kind of abuse they take in an 1/8 scale rig so having a really free
drivetrain is as much a matter of proper maintinence as what car you start
with.

I agree with some of the other posts about the MP9 though as they seem
to have the smoothest stock driverain provided they are built properly.

Ceramic bearing's are NOT needed What so ever....There are a few places they are ideal for but more places they aren't.

On the tracks in my area if you use ceramic bearings you better like cleaning them frequently. Too much dust. The only place I use them is inside my engines and even there I am not sure they are necessary. The losi drivetrain is pretty smooth once it breaks in. It will be nice to see the Durango buggy on the track I think it has a lot of new high tech in it that always gets my vote. But we won't know until people start to drive them.

I have a brand new losi 2.0 and it definetly has a smoother drivetrain then my mbx6 was when it was new, no question. As for the way it drives we will have to wait and see when I get it on the track for the first time.

After having run AE, Kyosho and now the MBX6...

The MP9 does have the most free spinning drive train out there!

Why go through the effort of removing the seals, cleaning, relubing, and resealing the bearings? Chances are great that the seal isnt on as good as new and dirt and dust will get in easier than before. Plus when high quality bearings are only $1 why not go that route.

Metal seal bearings may roll smoother but for how long? In Off-road you want rubber especially on the outside. Many companies are coming out with multi seal bearings with rubber on one side and metal on the other, so you can get a easier spinning driveline but with protection of rubber. My LHS carries Avid bearings and cannot keep 8x16 revolutions in stock.

I'm talking about rubber sealed bearings. Remove the seals and you'll most likely see gobs of grease inside. If you remove the seals, DEGREASE them, spray with a dry silicone lube, and reinstall both seals, you'll see a noticable increase in it's ability to spin freely. I first started doing it with the Revo, and it made a huge difference in the drivetrain.

Rubber sealed bearings have more resistance than metal shielded, which is why the Losi and Kyosho spin so free. They have metal shielded bearings.

Use whatever bearings you want, that's not the discussion here, it's about the car with the freest drivetrain, not bearing replacement.

I'm offering advice that will make any car have a free drivetrain and it only takes a couple hours of your time.

Losi Does NOT use Metal shielded bearings.


That's not to say you Cant, But out of the box losi's come with rubber sealed.
