Loadstar II Tribute — 3D Printed Flying Rocket
Print Profile(1)
Description
A 3D-printable tribute to the classic Estes Loadstar II (model 3227), designed and printed with my grandson as a weekend project. This is a full-size flying replica with a tangent ogive nose cone, BT-60 to BT-55 conical transition, and a clear payload bay for altimeters, cameras, or just showing off your payload to the launch crew.
What's included:
- Tangent ogive nose cone (hollow, vase-mode friendly)
- BT-60 to BT-55 conical transition piece
- Motor mount sized for standard 24mm motors
- Fits a clear polycarbonate or PETG payload tube (BT-55 ID, ~1.325" / 33.6mm)
Recommended print settings:
- PLA for all structural parts
- 0.12mm layer height for the nose cone (smoother surface = better aerodynamics)
- 0% infill on the nose cone (vase mode works great), 2-3 walls
- Supports only where overhangs require — most parts print cleanly without
- PETG recommended but not necessary for engine tube & screw on cap
Motor recommendations:
- Estes D12-3 — perfect first flight, gentle altitude (~400-500 ft)
- AeroTech E20-4W — drops right into the 24×70mm mount with no modifications, ~900 ft
- Quest Q-Jet E26-4W — composite alternative when Estes E motors are out of stock
Finished weight: ~0.70 lbs (317g) ready to fly
Built with love (and a lot of patience) with my grandson. Hope your family enjoys building it as much as we did.
