OH yes, Bad news, I got this sts 28 to hopefully beat my sons Losi LST.. Not happenning ! I ran a gallon on break in, took the 3 .01 mm shims out, put in a new #5 OS plug, ( I run 20 % nitro 12 % oil) and a 19 tooth CB and a 49 tooth Spur, and My son's Losi LST still flew by my savage like as mine was a Traxxas ELECTRIC STAMPEED, How sad, a savage cant beat a losi! ;( I guess I wil be selling my savage and get me a stock losi, 55mph out of the box! we had it clocked about a hour ago...
