Whistling Mortars

Hey all, I've made these mortars in 4 different types. one is a normal mortar, another one holds Super Snaps, another holds a ½" ball bearing, and the other holds a ¾" ball bearing. the bearings give it weight to fall faster and make the whistle louder. I got the whistle design off Thingiverse from WhiteTrashFPV. I made the ball bearings fit pretty well but they need glue to stay in. I used Bob Smith Industries glue, and it works great. These mortars are designed to be used with E-Flite Servoless Payload Receiver. I will attach a file with links to the materials I used as well as credits to original EDF Whistle creator.
