Man I wish you could have come to our modern battle this last sunday. We had a blast with fast tanks whipping around the field. My abrams did great with no failures and performed exceptionally with the 12volt ibu and red motors, though its still slower than a tamiya, i want to go up to something like a 480 motor maybe. My 5amp battery cam handle the run time just fine i think.
my only glitch was a few rocks that got sucked up above the track and got jammed above the track beteen the two return roller supports. Was kinda strange to figure out and find.
