Hi, can anyone explain to me the difference between muraco and punisher? A friend of mine has a punisher, out of the box it was unmanageable as too nervous it was always spinning so it was hard to drive! He changed the oil in the center differential (smoother) he changed the tires putting arrma outcast 4s (the stock tires are very heavy) this way the model is more manageable. So now I'm interested in getting a Muraco but looking at the parts list it looks like the same model as the Punisher....wouldn't get the same model, don't want to change the oil etc... Maybe I'm doing it wrong? What are the differences between the two models except the wheels? Also, is it true that the production model reaches 65 km/h? I've seen videos, some say 54km/h, others over 65km/h... What is the truth?
