Hey guys I have been looking into converting a Ryobi or Homelite when I saw the Ryobi FS advertised... If understand correctly it is oil injected and will have to have an oil tank... Is this a pain in the butt for R/C? What about power vs. 2 cycle? Also is there a lot of added wieght for the lifters, valves etc... I haven't even heard one run... Do they sound more scale? Not that a 2 cycle gas engine doesnt sound cool... Just havn't heard of converting the 4 cycles... Thanx a lot
