If the team wants to have their own tester, someone associated with the team will have to make one. The design details are provided in the problem statement. There are additional instructions posted on the Balsa Teams page on our website. Anyone can build the tester, and there is no outside assistance penalty for having a non-team member make the tester.
The Balsa Problem Captains in Northern Virginia hold one or two information sessions each year for teams and, at that time, permit teams to test a structure on the Regional Tournament tester. No team may borrow a regional tester, but any team may test their structures at such an information session. Check the regional website for announcements of these sessions.
