【實用工具app】Model Rocket Calculator|最夯免費app

A handy application to go where your PC won't! Will calculate parachute size, amount of drift, and projected altitude of your model rockets. Because of the approximations used, the large number of uncontrolled real-world variables influencing rocket trajectory, I cannot accept any liability for the failure of your actual rocket flight to conform to this projection.
