But I also dont want to put too much load on the batteries and burn up the esc. Batteries are turnigy 4000mah 6s 30-40c rating (no worries I have some 35c batteries on the way)

Gear for the intended use of the truck... and check the temps to be sure you are with operating limits...
Ok... some sort of update... earlier tonight I decided to mount a 20t pinion on the 1520 to see how well this thing would do with the additional load...
Well, to be honest... i was not surprised to see the 1520 handle its business with no effort... It was so quick going down the street.... I had a hard time
holding in the smiles when I blasted up and the parking lot... Rolling wheelies are even easier now since the wheels spin up so quickly... Needless to say,
i am still having a lot of fun with this truck..
This motor is AWESOME!!!!!!... I am still running it on 5s...
