I double dog dare you to do this at LDRS this year
Pretty certain their waiver can't handle it...
I double dog dare you to do this at LDRS this year
I'm not just speculating. It doesn't survive.You are incorrect about aluminum tape though. I have used it for 25 years on rc planes and jets. The backing is so sticky that if I made a mistake and needed to remove a piece, it usually took the layer of fiberglass off with it
Yes, but I think you might need to use some of that super-sticky Al Tape instead of plain-ole masking tape for that one, @StreuB1So hear me out....
What’s that nose tip made of?Some pictures of the damage.
The fin can was almost entirely unscathed. Just a little chip out of the leading edge.View attachment 625597
The nosecone is a bit worse. The tip got broken, and there are a few points of abrasion or mach rash. The blue indicates that it impacted the top of the avbay at some point. I'm not sure if I'll make a new nose or if I'll just fix this one.

The avbay was the worst. The Featherweight GPS antenna got pretty smooshed, and the Blue Raven sustained some damage. Fortunately both units seem to be largely functional, so the damage shouldn't be that bad. Still going to consult with the manufacturer before flying them again.

It's just a slug of proline epoxy with the end of the shock cord embedded in it.What’s that nose tip made of?
@Neutronium95 --
I really like your drogue -to- main setup !
I googled 'Half Cat Rocketry Cable Cutter' and I did find the Half Cat rocketry site but never found a site that sells or describes the 'Half Cat Cable Cutter',
Is that something you made yourself ?
It looks kinda-sorta like a hexagonal all thread coupler ?
Something I never considered ... it seems it would be easy to seal one end that-a-way ...

Do you have a picture of the shock cord where it likely wore through? Could you bore out the nut and smooth the edge so there’s less chance of wear. Alternatively, could you add a bit of heat shrink to the shock cord at the wear spot?Another successful boost, another recovery failure.
Tge GPS reported a steady 90 ft/s descent rate after apogee, but after descending a few thousand feet it rapidly increaded to 300 ft/s. I found the bulk of the rocket, but all of the electronics and fiberglass parts were trashed. I think that the shock cord may have been worn through from rubbing on tge hole in the nut it was tied through.

I'm feeling pretty dejected right now. This was supposed to be a proof of concept for future high performance projects, and I'm really not sure where to go from here. I think that the recovery system design is alright, but I don't want to fly it untested on an even higher performance flight with a nearly irreplaceable motor.
No. I wasn't able to find the nose cone, parachutes and shock cord. It likely drifted significantly farther down range, and the tracker wasn't attached. I didn't have the energy to search a bunch of scrub land for it.Do you have a picture of the shock cord where it likely wore through?

Flight 3 was also a K1103.What motor did you fly on flight #3 ?
Is your RMS 54/1706 casing OK ?
Does your fin can look OK other than any damage from the landing ?
Yes, the exhaust from flight #1 and flight #3 look VERY similar, especially factoring in my crappy frame-grab.Flight 3 was also a K1103.
The hardware seems intact. Maybe a few scratches, but nothing obviously wrong. It'll get a more thorough inspection before flying again.
The fin can is almost salvageable. Unfortunately some of the impact damage goes down below the top of the fin roots. I might remove the fins and attach them to a new tube in the future.
Some video of the boost, thanks to @JoeBarnard
Also some pad cams from a friend.
