Last Friday (September 22) I participated in a science workshop with high school students. The students build their own water rockets and this was a perfect opportunity to test the tower launcher.
Back on June 15 the Hyperion I rocket got stuck multiple times in the tower launcher because the guiding rods narrowed at the end of the launcher. I have solved that with a triangle made of aluminium profiles and 3D-printed corners (see image). To see the launcher in action, check the video from Friday's launches here.
