Can't say enough about OBR engines nothing else compares! This 7.5 hp engine was bought last year 7/8/14 for my losi five t roller. Took my time building out the truck and wow was I impressed when I finally got it all together. Strong engine and keeps getting stronger, but with a growing family I just don't have the time anymore. Comes with a victory pro tuned silenced pipe which OBR recommended, turtle racing billet crankcase and clutch housing, team chase carb filter, and ddm air filter and to top it off a 990 carb! All you need is throttle linkage and a pull start to complete and you are off. Engine only has 5 tanks of gas through it.
