VS Racing VSR03-EV2 .21 nitro on-road engine
Coming from World Champion Products is the VS Racing VSR03-EV2 3.5cc nitro on-road engine. Based on the O.S. Speed R2103 the super-long stroke engine is developed for high-class competition use and it features a 7-port design, CNC-machined piston and a 14mm “Rody” modified and DLC-coated crankshaft. New to the EV2 variant are optimised modifications to the crankshaft as well as a new combustion camber insert with a silicone O-ring that ensures a cleaner area between the cooling head and the crankcase. The engine is available separately or as combo set including VS2098 or VS2069 exhausts.
