Team Orion has announced their new CRF 21 V4 3.5cc off-road competition nitro engines for 1/8th scale Buggy e Truggy. The two engines share the same design but differ in ports (7-port Factory WS Edition and 3-port Racing). The 7-port engine has a better progressive throttle response and top speed, while the 3-port variant has better torque.
Both engines will be available in hobby shops very soon.
