The Jammin CRT.5 is a 1/12-scale, nitro powered (.12-based), 4WD truggy. It’s an all-new design, which does borrow some of the CRT parts. We liked the smaller scale, but the larger size than other mini’s allows it to use standard electronics, and more important a standard .12 engine. The “micro” minis are fun, but their engines are often very temperamental, and you can’t run them on surfaces that larger scales can tackle.
Features
• 4WD with front, center and rear diffs
• Uses standard .12 engines for easier tuning and more power
• Long suspension for better handling and real off-road capabilities
• Uses standard size electronics
• Wheels and tires are common electric buggy compatible
