Search Youtube for "losi 4 stroke" should be the first 2 videos that come up. There of my 4 stroke converted Losi 8T.. Still in the testing stage, running a $80.00 .52 converted plane engine Tell you one thing, these 4 strokes will burn a clutch up in a few days! If i could get the power to the ground, id switch to racing only 4 stroke. Im also getting 12:30 to a tank, and gas is cheaper
