RA2105 Lolita Body
The new Body for the Scalpel is very low to the chassis and the big spoiler at the rear makes a lot of downforce. The Body is for the 4 Cell Kit and for the 6 Cell Chassis.
RA2201 6-Cell Chassis
2mm Chassis with 6 Battery Slots for low center of gravity. The wheelbase moves from 130mm to 142mm. This is also for a better performance at long straights.
