is this normal wear?

Ok so this is the setup.
Ofna Jammin Crt .5
Feigao 9L
Mamba Max
Castle BEC
Maxamps 4S 8000
Hitec 5955

After running, i noticed i had a little bit of residue where my pinion and spur meet. Since they are both metal, i DO expect some wear but i am just wondering if this is excessive or about normal.

here is my battery setup.
This way i can use them on my crt and my e-savage.

That looks pretty normal to me......my Savage eats metal gears up pretty fast....torque breaks stuff...How long has it been on there?

that was the first run with a 4s

Any dirt, dust, moisture or otherwise that gets caught in between the spurs will be thrown off in that spot, by centrifugal force.

wooooooo

this thing SCREAMS on a 4S too. esc stays cool and the motor is around 130

I was using a RRP hardened steel spur and pinion on my GMaxx with a brushles set-up.

It would turn the pinion teeth into razor blades after 1 day of racing 2 heats and a main.

I got tired of buying pinions and decided to swap for a RRP plastic spur and standard pinion by Traxxas.

I put over 6 races days on the new set-up and neither gear show any signs of wear.

Sometimes using hardened steel for the gears isn't always the best set-up.

do they make a spur for the crt thats plastic?

i posted this in nitro, can i get it moved to electric. sorry bout that

No problem, Done.

I agree with this. I have always used steel clutch bells, but plastic spurs on my nitros. I

Look who built it.

The residue is dirt,trash, and diff oil. I have a friend that ran the same type pinoin on a Losi 8 on 6S.

 

[flm_savage]

you did an excellent job on it. I am doing a little wire cleanup and then it will be perfecto.

You could also try some dry wax based lube to help cause less friction on the pinion/spur which may make it wear longer. I know it works well on my cvd's, plastic spurs and diff ring/pinion gears.
