Tried multiple gearings and tire combos. Last outing shredded a 19 tooth Tekno pinion so gone back to the hardened steel Traxxas pinion 20 tooth with the 50 tooth hardened spur also from Traxxas. You need to leave the loctite for a minimum of 24 hours on the pinion. Running the stock tires this is the best this truck has ever felt. Running all stock electrics.
No more tinkering! Enjoy.
