This is not a modified scooter motor. It has been designed purely for R/C large scale aircraft. Unlike most other gas plane engines built in the region, this motor was designed, milled, lathed, forged, cast, tested and assembled with the single goal of providing the best power to weight ratio, needed for big scale R/C planes
