The Smoking Airplanes SA-201 is an aircraft smoke system designed for aerobatic and demonstration aircraft applications. It injects smoke oil into the exhaust system, where the oil vaporizes under high exhaust temperatures to produce visible smoke trails during flight operations.

The system is commonly used in aerobatic aircraft for airshows, formation flying, training demonstrations, and recreational display flying. The SA-201 kit typically includes a pump assembly, control components, fittings, tubing, and mounting hardware for installation in compatible aircraft.

Key features include:

Aircraft smoke generation system for aerobatic applications
Injects smoke oil into engine exhaust stream
Produces visible smoke trails during flight demonstrations
Electric pump-driven oil delivery system
Designed for lightweight aircraft installation
Compatible with aerobatic and experimental aircraft setups
Includes plumbing fittings, tubing, and mounting hardware
Built for vibration and temperature resistance in aviation environments
Used in airshows, formation displays, and aerobatic training
Suitable for aircraft modification and specialty flight operations
