Description This is the ultimate precision launcher for usage in ELG competition. It complies with all 2020 Science Olympiad restrictions for the Elastic Launched Glider event. Aim and launch with a single hand so that you can get the exact bank and pitch angles every time without worrying about whether your launch tension is correct. You need to supply a wooden yardstick from the hardware store. Warning: non-J&H Aerospace ELG gliders will require a carbon bumper to be added to maintain correct alignment on the launcher and avoid damage to the tail surfaces. Demo: Build Instructions:
