Control Line Smart Timer

ClSt (Control Line Smart Timer) is an open-source, high-precision active flight timer and throttle governor designed specifically for F2B (aerobatics) control-line model aircraft.
Unlike static timers, ClSt uses an IMU sensor (MPU-6050 / GY-521) to analyze the model's physics in real-time, functioning as a "virtual co-pilot". It continuously recalculates and adjusts the electric motor throttle (0.0 to 1.0 / PWM) to maintain a perfectly constant airspeed along the entire flight trajectory, regardless of wind conditions and maneuvers.
The project repository includes:
1. ClSt Core firmware for Arduino Nano V3.0 (ATmega328P / FT232).
2. Mathematical simulation code integrated and tested within the PicaSim flight simulator (Bullet Physics).
3. Android Application layout (MIT App Inventor/Flutter) for on-the-field USB-OTG telemetry monitoring and coefficient tuning.
