There comes a time in one's rocketry pursuits when there is an insatiable desire to put big motors into small rockets. That time is upon me.
I've seen many MD projects on TRF and found the design and construction challenges intimidating and maybe a little beyond my skill level - particularly with fin attachment. But with the Hyper54, the aluminum bolt-on fins give me a practically indestructible fin can that takes about five minutes to permanently secure to the rocket without a drop of adhesive. This feature alone is what prompted me to move forward with an MD project (the fact that they look super bad-ass is merely a bonus).
Here I've temporarily installed the fins, retainer, and K740 C-Star motor. The SMT Designs av bay is shipping today (4/25/22). I have some hardware and a few other items to collect and then I'll attack the build.
Maiden Flight Plan
Tentative date: 5/21/2022
Empty weight: 61 oz. (3.8 lbs.)
Length: 69"
Motor: CTI 54mm 4-grain K740 C-Star
Expected altitude: 13k'
Max. velocity: Mach 1.6
Max. Acceleration: 28 g's
Recovery: Dual deploy via two RRC2L's. 36" main, ??? drogue (considering streamer or drogueless)
Tracking: Dual Tracki GPS transponders and Marco Polo unit
Regular updates as the build progresses. Stay tuned!
