Tropo-1 is the first rocket to be made by ARRW rocketry and demonstrated thrust vector control (TVC). The rocketstood at 3½ feet with a 3-inch diameterand had 1 rocket motor. Tropo-1 included a TVC function that the rocket was controlled by. This function was a challenge for the team to work on and many revisions were made to the system. Upon the rocket's launch, the internal flight computer failed to read the gyroscope sensor data, leading to the rocket veering off course.
