Have a set of Badlands and AKA Crossbrace on Corr style Rims but not sure if either of those are suitable for Grass.
Also any general set up info? Are Tapered pistons worthwhile?
You will want to look for tires will bigger lugs for grass racing. I don't know if I would go all the way to Badlands, but they do work. Just have to be careful when you turn since they tend to dig in and cause traction rolling. I have a set of knockoff Badlands and they are great for the grass. Crime Fighters and Calibers also make decent grass tires.
For gearing in the grass, I would start out around 44/16 or 44/17 with that motor. Grass is hard to predict. Taller grass will require a smaller pinion to control heat. For dirt use, an 18 or 19 pinion would be perfectly normal. I would start low and monitor the temps. If you find the motor and ESC temps to be right around 100F, you can go to a taller pinion.
On a side note. You may need some capacitors on your receiver if you are using the MMP's BEC with that servo.
