Integrated Fin Can for supersonic flights on 38mm minimum-diameter rockets
Description
I Have Flown This Several Times To Mach 1.9 (According To Rocksim) Since The Fins Are Perfectly Aligned Every Time. All You Have To Do Is Print It (10% Fill, Normal Speed Print, With Rafts) And Epoxy The Fin Can A Quarter-Inch Or So Above The Bottom (So You Can Use A Ring Of Duct Tape For Motor Retention) Of A 18" (Or Longer) Strong 38Mm Motor/Body Tube (It Is Perfectly Sized For Blue Tube) And Tape A Golf Ball To The Top (Range Balls Are Free Nose Cone + Weight, Which You Will Need). If You Have Extra Epoxy, Lather It On The Fins For A Smooth Finish And Extra Strength. The Launch Rod Lugs, Rail Guides (Which I Highly Recommend For Rigidity) And Fin Fillets Are Built Into The Print. Ready To Fly In 5 Minutes With Single Use Aerotech Motors (I Have Flown The J270, I140 And I280 To Go Supersonic).
