Transfered the Design of the Acustrike MEGA dart to ULTRA. Your ULTRA darts will fly straight now. No suuports required. Print with face down. You may want to run a 1/8th drill through the hole to make it round again. Totally optional. Also make sure to sand off the elephants foot after printing. Can cause loading issues in the ULTRA 3 AND 5.

To instal, gently peel the ULTRA head off, picking a spot and then working your way around the dart like your peeling an orange. It is important to make sure the foam hexagon underneath stays intact for maximum dart life. Once you have it off, super glue the Accustrike head on.
