Description
Great BlastSonic is driven by Retsu Seiba in "Let's & Go!! Return Racers!!", continuing the visual identity of the earlier Sonic-series cars with an updated body. The nose and rear wing components can be trimmed with a modeling knife, giving builders a choice between two distinct body configurations from the same kit.
It uses the AR chassis with yellow 5-spoke wheels on low-profile tires and a 3.5:1 gear ratio, sharing the platform's air-cooled interior routing, independently removable underpanel and diffuser, and low-friction rear skid bar for slope sections.
- Length: 155mm, Width: 97mm, Height: 44mm
- Wheels: yellow 5-spoke; Tires: low-profile
- Body: convertible between two configurations via knife-trimmed nose/wing parts
- Chassis: AR, gear ratio 3.5:1; motor included
- Requires 2x AA/R6 batteries (not included)
