Default Underdrive in Both Axles + 9t Pinion - TRX4

I had been running a 9t pinion in my TRX-4 for a while and it was smooth on the low end and speed was still fine. But i figured if i geared it a little more, i can use a more powerful motor without losing control or having issues stalling
Even general trailing is fine with the 15t motor in high gear.
Should be even better with a Hobbywing AXE fitted eventually
