So i took the Beast out for its first real test run . Ran for about 45 min in low gear then about 15 in hi once i finally worked up the nerve. At first while driving in the back yard and on some trails the tires seemed to wobble a lot in low gear running about 10mph. Must have been from the ground being frozen because once i hit pavement at 30mph it was smooth as silk. Pulled the wheels off the ground a few time in low but never tried in hi for fear of breakage. The creek was frozen over so of course we had to try that . Even drove slowly through 2 inches of water without getting water near the electronics . I'm guessing with the load these tires put on the motor there was no cogging what so ever. The best part was the noise the tires made at 30mph on pavement just like a real truck with some big mud tires. After an hour the motor was hardly even warm to the touch maybe 100 degrees. The only bad was the steering and i didn't have any drag brake so it just free spooled down big hills.
