Abnormal gear wear on Savage Flux

Well upon further investigation and research into this problem, I decided to take matters into my own hands, less I start replacing gears all the time. The stock gear is actually STEEL based,HPI #86097. However, it is NOT hardened steel, which would explain why it wore out so fast. http://www.hpiracing.com/products/en/86097/
I checked it out further and you definetely don't want the aluminum gear set from HPI #86136, it'll be worse! http://www.hpiracing.com/products/en/86136/ So my original theory was wrong, the STOCK Savage drive gear is standard STEEL, not hardened STEEL or ALUMINUM.

Lucky for me, my LHS has a replacement 86097 steel drive gear handy so I purchased it along with some HPI Heavy duty grease #Z168 and went about to grease the entire center diff and im gonna see how much that helps my gear wear out. http://www.hpiracing.com/products/en/Z168/

Hopefully someone soon will come out with a HARDENED STEEL version of the drive gear.

You can most likely harden it yourself. Just need a decent torch and some oil. I may try heating mine slowly to cherry red and then quenching it in some 30wt oil. I would like to know the actual material that the gear is made from, it may need to be air quenched instead of oil quenched. i still think my oil bath idea is the way to go...

Thank God! My prayers have been answered! I'm picking one of these up as soon as humanely possible! Thank you HPI for listening to your customers!!

Looks like a good mod. I plan to run mine as is with some motor oil (synthetic) and see if that prolongs the life of the gears. How much time (hours) do you think your tranny has on it?

The original drive gear? Uhh, I think 5-6 runs on 4S. I haven't run it yet with this new drive year and grease yet.
