It's kind of amazing how many public figures will respond to tweets by some random dude on the internet (no offense to DAllen here).
Haha no offense taken I am definitely a rando in Toreys world

You know, I've watched all of your Youtube videos prior to buying this kit just to get an idea of how its going to fly. You have some great footage. I mean...I assume this is yours?
15' flare chute. https://aeroconsystems.com/cart/all-parachutes/15-foot-parachute/ looks like no longer available. Originally got 10 for $50 direct from TPL ($5 each) then Alwaysreadyroketry had them for IIRC $70 each for a while.Love it! What size main is that?
In this video the build is able to survive the flutter.
In reference to John’s video here is another, clearer video, shows flutter clearly, vibration from the flutter also appears to make the road “squiggly”, and the smoke trail does the exact same thing.
Initially i wasn't sold on the flutter diagnosis but i am now, seeing John’s video and comparing to this one.

Yes I'm familiar with the website. I bought a few flare chutes there in the past they got great prices. Anyway that's an awesome video that looks really cool with that big a parachute bringing it down great video.15' flare chute. https://aeroconsystems.com/cart/all-parachutes/15-foot-parachute/ looks like no longer available.

It's time to retire to make it a shelf QueenSurvived yes but I sure wouldn't trust any of those fins or fillets to another flight. Probably hundreds of micro cracks all over that structure just waiting to catastrophically fail on the next flight.
Looking at the video I have of the flight everything looks good until about a second before destruction when the smoke trail from the motor sorta ripples or spirals maybe (rocket doesn’t appear to be spinning that much). Those with more experience maybe can tell if this is evidence of flutter causing the rippled smoke trail?
Here’s the first pic from my video showing everything normal:

Milliseconds later some rippling of the smoke trail:

Haven't read the whole thread, but I was standing next to DAllen when this one went up. Sad to see, but...dang, it was interesting to watch. As someone planning for an L3 cert attempt, it was one heck of a learning experience.
Also - Talked with DAllen a couple of times, both at the flight line before and after the flight and then at his car afterwards (with half a rocket and a pile of confetti sitting there on the ground) and I would like to compliment his great attitude - "these things happen in rocketry", you could tell bummed (as anyone would be) but certainly not beaten. It was an excellent attitude that I will look to emulate in my own pursuits.
Plus, "It's Round, we checked....

In the spirit of post-mortem, do you have pictures of the rest of the fin can and are you willing to open it up?
ah, i misunderstood your e1337 k-r4d spellingYou flew on the M1297 right Dave? I think Loc has a video of this kit on that exact motor
Never stepped foot in NY state, I'm from Texas and work in Rocket city (H-ville Alabama). How to fly the big stuff? Same as everyone else, take a trip out west.
ah, i misunderstood your e1337 k-r4d spelling
But, we have seen wood glue fail several times on these kits that we've drag raced. From the 4" to the 7.5
Did my L2 and L3 on LOC designs, both of which I know would survive any motor you stuffed in them. Cannot blame LOC, their kits are fabulous.

Yep, helps prove the point then. 15 year old LOC kit still alive and kicking after multiple owners and many flights.That L2 rocket looks VERRRRY familiar... Almost exactly like one down in my basement...
Tim, what is the Hope N' Pray kit, a custom or an original LOC kit?Did my L2 and L3 on LOC designs, both of which I know would survive any motor you stuffed in them. Cannot blame LOC, their kits are fabulous.

I worked with Barry (former owner) on modifying a Bruiser EXL which I originally purchased from Ken Herrick at Al's Hobby Shop in Elmhurst, IL. Barry cut new fins based on my Rocksim modifications.Tim, what is the Hope N' Pray kit, a custom or an original LOC kit?
