Methanol, as a fuel that can be produced from renewable resources, provides the potential to reduce dependence on fossil fuels. Nitro (30%) has specific properties that improve engine performance, especially Thrust and propeller rotation. This experimental study aims to understand the effect of both fuels on the Thrust and propeller rotation of an OS 25 LA engine. Results show that nitro fuel (30%) produces higher Thrust (1,464 N) and faster propeller rotation (11,325) compared to methanol-castor oil. Combustion efficiency was also higher in nitro (30%) (18%), indicating more optimal fuel energy utilization. Thus, the use of nitro (30%) can be considered as a more efficient and quality fuel option to improve the performance of the RC OS 25 LA engine.} }
