Yeah those servos work great on the rustler, but you're talking about a T-Maxx here. The rustler is A LOT smaller, and 2WD, the Maxx is 4WD with much bigger tires.

The 2075 will be fine on throttle, but I agree with most, get a better servo for steering. They may seem to work fine now, but you will see in the future.

You can get one of those Savox servos for probably around 50 bucks and you'll never have to worry about that part of your truck again.
