I bought my T-maxx 3.3 and ran it in the back yard. Got a backflip off a little hill in the yard. Stoked me out a little so I had to build a ramp.. Pulled a triple once but landed it wrong on the roof maybe I should have throttled it more. Oh-well Now I'm trying to get it running again. lol Won't start. Guess that 15 to 18 foot high impact hurt!
