What engine/gearing/tires are you running? Is that sand or loose dirt? Gear cover or no gear cover? The reason I ask is because I drive on loose dirt/grass with no gear cover ,29/31 gears, excavator tires, 28.5cc, xcan, and I have got 5 tanks now on the same set of plastic gears. It is hilly and I do donuts and jump so I do drive medium hard.

engine is a 28.5cc ported cylinder
Gearing is 30/30/25/25 25's are Ramtech steel


Tires are excavators


Gear cover installed but ventilated, it realy sucks I have to open it up to cool the gears yet the sand eats the gears.


That wining sound is the plastic CD gears screaming for mercy. lol


I was running 29/31, but I used them all up, and all I had left was a set of chewed up 30's. Well, all my plastic gears are gone now, both of my redcats are on the shelf waiting for gears, I refuse to buy any more plastic gears. I blew 40+ usd of them out my A$$ yesterday and didn't burn 2 tanks. I will concentrate on my 5T now I suppose.


I am patiently wating on steel gears.
 
I bet they are getting eaten from the sand +ported 28.5 + big gears + vented cover. A completly removed cover will cool them more but the sand would really get in there. Do you think the sand will mess with metal gears? You could have an interesting test on your hands.

Yep, I would have given the prototypes a real test. I guarantee the sand is eating them, but they sure look melted when they finally fail. I hope the gravel doesn't hurt the new steel gears, the Ramtech 25's are holding up just fine. I have put many gallons through my MCD's in the gravel pist with no upgraded steel gear failures, everything else on them breaks though.


I am looking forward to the upgrade. With that done all should be good. I beat it this weekend and all that I broke was the plastic gears, and front bumper, a barrell roll from the top of the gravel pile front to back. WHOOPS. lol
