Slipperential of plastic spur gear version, possible?

Hi, I would like to ask will it possible to have slipperential with plastic spur gear?
Maybe this need Mike to answer.
I love the slipperential but I love it in plastic gear, since it is much quiet.

I believe the plastic gears had issue with the high temps.
The steel gears are not loud at all so if you are worried about the noise, the slipperential steel gears are much quiter than a standard steel gear diff.

Interesting. How come? Due to different kind of steel or teeth design?
I thought steel gears are always noisy.

Read all the threads about the slipperential unit, the tooth profile on the spur gear is made to be quieter.

I have read the relative theads. Thanks. Still a surprising news for me.
Is it as quiet as a spur gear or just a little bit noisy?

ive been asked if i was running a plastic gear when running my slipperential because it was so quiet, just match it up with a new rcm pinon and set your mesh right and itll be very quiet.

+1 People are really surprised how quiet metal gears are

plastic will melt if you run too much slip. trust me.

Yup!
That was the big issue on plastic.
Serious melt down under hi heat and stress.

I believe so. However it depends on how you want to use it.
Most people run their Revo with plastic spur gears on slippers and they run them with little slip.
Some people might want to use Slipperential with much more slip and they really need steel spur gears.
ps. Adapters might be a solution to heat and stress.

Our new mod .8 spurs are really quiet. :)
I may offer a plastic spur with a "too much slip will melt it" disclaimer, though the mod .8 gear is almost indiscernable from plastic in use - it is very quiet.

Do the steel and delrin spur gears have the same thickness, or delrin ones have thicker dimension?

By the way, I have questions about the thrust bearing.
I wonder if the dust and dirt affect the function or shorten the life of the thrust bearing?
Is it necessary to have light coating of oil to the bearing in assembly?

[RC-Monster Mike]

The plastic spurs have a wider tooth profile than the steel spur gears.
I wouldn't oil the thrust bearing, as it would attract dirt. Left dry, the cetrifugal force of the spinning diff will keep it clean. The bearing only rotates during slip and will be rotating way under its rated rpms - I have never seen a failed thrust bearing on the slipperential.
