what pinion for a steel spur

[stampy]

im working on a making a bomb proof bl monster truck and im just wondering what pinion material should i look for to use with a steel spur?

You will need a hardened pinion gear to last any length of time on a steel spur gear. The steel pinions I have can be case hardened(I may try to do a few of these myself in the near future). Without treatment, they only last for a handful or so of battery packs.
Welcome to the forums, also!

Thanks!:D ya i probably wont do a steel spur its much cheaper to replace a $5 dollor spur then a $10 dollor pinion plus the down time ill have to wait for it to arive. thanks for the reply

Ja, steel spurs are unwise, IMO. I can imagine the metall filings wound be annoying, too. This is something for nitro cars, at least they have no strong magnets around.

I also read somewhere that steel pinions on steel spurs create radio interferance, don't know whether its true or not.

[RC-Monster Mike]

Not necessarily, but potentially. Any metal to metal is conducive to causing radio interference.

I was running a steel pinion/spur, that snapped the shaft of my Hacker C50.
The teeth on the pinion parted company, and jambed up in the spur...............I found out the hard way.....:o

A hardened pinion gear would be necessary to avoid the "munching" you experienced!

He tells me now :rolleyes: ;)

I now have one of These ....A kind of fit and forget spur, well worth it.

[RC-Monster Mike]

Agreed! The strobe setup works very well. I have them on all my electric maxx type monsters.

Mike, can you get the Ofna Ultra LX centre diff that takes those 51t plastic spurs ? and can you get the Delrin spur to fit aswell ? if so i'd like to order one please.... ideally i'd like the centre diff, the diffmount hardware & atleast 2 x delrin or plastic spurs...

Do i need to shoot you a mail ?

Cheers

Andy
