Roche RC has released the Rapide, a F103/F104 conversion kit. The wheel base is based on the F104 as 270mm, with a selectable width of 187mm (F104) and 200mm (F103). With a newly designed motor mount set, the width between the left & right mount is wider than the Tamiya original by 5mm meaning the main drive shaft bearing is closer to the wheel adaptor. At the back there is a simple design with adjustable “U Plate” rear suspension and there are different thickness “U Plate” to setup for different track condition. A narrow main chassis design makes it more stable with faster corner speed and moreover the chassis is compatible with Tamiya F104 bodies.
