Love the creeper, cheap and fun.  only complaint is the servo operated diffs don't like to stay locked, so they are now zip tied to the locked position.  Running the novak Rooster crawler and 55T combo with a 2S.  After getting the redcat sumo crawler and seeing the steering
modes, thought to myself...gotta have it in the creeper.  Gonna have to figure another way to power my axel lights if I go that route though since the 3rd channel will be taken up by the rear steering servo.
