The O.S. Engine 21VG (P) is a practical choice when upgrading 1/8 scale Ready-To-Run models for ROAR competition. Many stock motors lack the control needed for racing, and the 21VG (P) brings reliable mid-range performance that suits a variety of track conditions.
This engine excels at delivering usable mid-range output, which helps drivers get on the throttle earlier out of corners. That balance makes it popular among newcomers and seasoned racers who prioritise corner speed and control over raw top-end.
The 21VG (P) uses an ABL piston liner to simplify break-in and extend component life, helping keep maintenance intervals reasonable. Its single-piece crankshaft design with rear exhaust supports off-road durability and steady torque delivery during long runs.
Featuring a 2-needle carburetor, the 21VG (P) is straightforward to dial in, even for those new to nitro tuning. The broad one-piece Tornado head accepts standard glow plugs, making replacements simple and economical between race days.
The O.S. Engine 21VG (P) is well suited to RC drivers aiming for consistent mid-range performance and low-maintenance setup, making it a solid option for ROAR-style racing programmes.
