Ive never used one but i saw one for the first time working about 2 weeks ago and it looked promising......... i bet it works i would jsut be worried about how long a engine broken in like that would last............i personally wont use it till i see how well the engine runs they day i saw the break in we couldnt see the motor actually run on the track becuase the guy needed cluch bell bearings (i think) once i see it run after a few gallons i will problably buy one since im always needing to break in motors





it threory it should work 100% its takeing the same principal as breaking in a airplain or heli motor.......but still ide like to see the performance first before i buy one but if i like one i will 4SHO buy it.......look into the RD logics one i think its only 100 bucks that the one i saw beining used
