The Thunder Tiger Pro 70 is a riot, I have five of them. I would not say they are as good as a Picco 28 in a monster truck application though, due to their low rpm. That being said, go to you tube and search for Thunder Tiger EK4 or EK 4 and watch some of the crazy power they do have. They are hard to tune and burning a gallon a day is not unusual, another huge plus for the powerful 28s. Thunder Tiger used a really tall tire to make up some gear ration and take advantage of that torque. They actually have a piston ring, run best on 30 percent plus fuel with added castor oil. I use Byrons 33 percent heli fuel with four ounces of oil added per gallon. With two of them running, it is pretty easy to spend 50 dollars a day on fuel.
