Gearbox Td2 dirt

[?? (Astute)]

Yes we ride a lot in dirt and But sealed al holes and use liquid rubber gasket. But still it’s eating gears. 2s lipo not very fast motor and slipperclutch(with correct pinion gear)It starts super smooth but after a couple of accu’s it becomes very noisy. 
Is it to fragile? Never had before with Losi or even cheaper dt03. 
Very nice driving car though, only frontsuspension need tweaks.
