Rear Aerodynamic Wing for Off-Road RC - Yokomo YOKZSGWB Gokuraku  [YOKZSGWB]

Overview of the Gokuraku rear aero

This Yokomo YOKZSGWB Gokuraku Off-Road Wing is a scaled rear body wing for off-road model cars and typical hobby shells, presented with a focus on handling and fit rather than promotional claims. It is intended for tuners and hobbyists who adjust aero to refine behaviour.

Operationally, the wing provides an aerodynamic surface at the rear that changes downforce and airflow separation behind the shell. On loose surfaces this can influence rear traction and pitch, offering tuners a discrete adjustment to use alongside suspension and weight settings. Effects are proportional to angle and mount height, so try small incremental changes when testing.

Fitting is straightforward on bodied off-road models: use existing body posts where they match, or carefully mark and drill holes where the shell and mount points allow. Fasten with common hobby screws and trim the shell only as required to maintain clearance. Always confirm the wing clears tyres, suspension movement, and antenna in full travel. Trim gradually and test fit often to keep the intended aero shape.

Tuning notes: use the wing to fine-tune rear stability; avoid relying on it as the main source of grip. Make measured angle and height adjustments and test in repeatable conditions to see lap time or handling differences. Combine wing settings with suspension and weight tuning to isolate what the wing changes.
