Starting a new Falcon Heavy build. Scaled to BT-55 body tubes. Body Tubes and Motor Mounts are from Estes, with the some parts from a Designer Special Kit, although I did make the 2 engine hooks from windshield wiper blades (I had already used up the ones in the kit). Plan to fabricate my own booster release mechanism similar to the one sold by Apogee with their booster pod kits. Center core has a motor mount for a 24mm motor, boosters have motor mounts for 18mm. From end to end it should stand right about 24 inches. I am going to sand down balsa blocks for the booster nose cones, and I found that an old cardboard tube from some kraft paper was a perfect fit for BT-55 couples/nose cone bases. I am debating having a friend 3d print the Nose/Fairing for the center core so that it opens on release, or just making a balsa block plus body tube/transition nose cone from scratch. Unless I can find a bunch of mini nose cones (old pen caps maybe?) I will likely have a friend 3d print that for the motor end as well. He is certainly planning to print me some grid fins and landing legs. I will have him include slots/tabs on the landing fins for attaching clear polycarbonate fins for stability. More to come...
Motor Mounts, Prepped Booster Balsa Nose Cone blocks
Booster Release Mechanism Balsa Spacers, sanded to match BT-55 contour. Gap is 5.5mm between body tubes for scale.
Boosters held to center core with rubber bands for visualization.
