The S15 blends performance features on the popular Silencer body with features such as mid-body winglets and rear stabilizer kick-up. The roof of the body remains strong with the upper fin in position for stability and tracking ability. The engine area remains clean and a deep rooted position allows the engine head maximum side exposure to air and escape. The front and rear body mount area is cleanly designed and allows for a drop-fit on the Mugen MBX-8 and older MBX-7 kit variants.
