do you know if there is a backplate for using the roto start system? I am about ready to buy a new engine for my sav x

don't fall into the manufacturer HP hype. That is off a propeller dyno. if you want true hp go here www.nitrodynesystems.com or extreme rc has a full list of all the engines they have tested. don't just go by hp go by the power band also the k4.6 ho has limited low end grunt but in the higher rpm band is were it has the most hp. it has long legs. the longer the run the faster it gets. this is the dyno most engine manufacturers are going to. it is a real dyno running a dyno bench marking program. go to the engine data base. CEN says my 7.7 has 5 hp nitrodyne and extreme rc say 1.35hp. you be the judge.
