So, I'm NOT supposed to tether the rocket to the pad...that explains alot.

Very educational.

What camera did you use for this?

No... read the narrative- it was not teathered, I was trying to fly it with 5 burning and it didn't work. BTW, I did it with the same rocket last summer and it worked fine- flew like a champ. This one just went wrong a bit. Actually I'd have never figured out the snag if I had not had the camera running because the rocket looked just fine- it just looked as if it went up and ran out of juice somehow.

The camera is a Casio EX-F1.... love the thing. Shot three vids yesterday and they all came out great, it was a very good day when even a failure comes out looking cool, don't ya' think?
 
Actually I was thinking it was a good impression of the SpaceX Grasshopper.

BTW-The video was shot at 600 frames per second because the rez. is better than 1,200 FPS
 
Cool video. Darn clip whip getting in the way when all the motors don't light. Then the unintentional flash pan ignition. Just say yeah "I meant to do that, was going for big mission points for the early American Space Program." "Flopnik", "Kaputnik", "Oopsnik", and "Stayputnik all apply. And it isn't even a Navy rocket! Now we know the Army had some sad days too.
 
Very rarely do "cool" and "funny" meet at the same intersection. This was a delight to watch (although a little painful) and entertaining. The camera/footage and the soundtrack make it a real gem!

Nicely done.

Did the rocket survive in re-flyable shape, or did the rear end get cooked by the exhaust backwash?

Good thing you had a "channel" type launcher with the exhaust being ducted down and away from the rocket. If that had happened on a launcher with a solid blast deflector plate, the whole rocket would have been torched all the way up to the nose cone.

The video did have a very cool 'retro' look reminiscent of a lot of those early-1960s 'launch disaster' videos.

The rocket did not even have any discoloring (amazing eh?). Even the trailing edges of the fins show nothing at all. It had more distress by my handling it with my rust-dust covered fingers after cleaning off the launch clips! The aft bulkhead also showed not a single discoloration. I'll be using a different airframe for the next flight, however, because the camera seems to like it better due to its different markings. I'm also going to do one of these with the Saturn IB on the milk stool... could be fun. There will be LOTs of upcoming videos using this camera, but ya' really have to learn how to use it.

Now, the pad is a WAY different story... it got cooked pretty good on the deck.

You're right- that's exactly why I used that pad! Also the angle of impigement is very steep. I love the way the flames lick out of the sides of the pad too. Plus it gives a real clear view of the flame.

"Retro look" Yeah- my wife saw it last night and told me it reminded her of that old V2 development film.
 
Wes....the rocket is pretty cool looking....the sound track is awesome!
would love to see your Saturn 1b liftoff from the Milkstool!!!
 
WAIT! I thought A8-3s were only for "squirming hatch-blowers".:wink:
 
Indeed... however, I have a ton of the things laying around because every time I buy a bulk pack it has a bunch of A8-3s in it. Now I've found a use for them. For these high-speed videos, the rocket only has to fly out of the camera's frame- after that, who cares? So an "A" engine is just dandy for that.
 
FANTASTIC VIDEO! I think this qualifies for the "best unflight video ever" award

I'll say!

The price on the listing linked at Amazon is more than a thousand dollars more than I paid for mine and I got it new off of Amazon!
 
Damn I'm sorry I missed that one, I was only there on Saturday. I didn't go on Sunday because after Saturday I was all out of sweat.
 
Actually the video looks far better than the actual event which was mostly a "Pbbbbbbbt!" and that was that. So you did not miss much. There was, howver, a nice breeze on Sunday.
 
I filmed an engine held in place above an aluminum can flame deflector to see how well it would do - as a test for a future video - and the engine quickly burned a hole in the aluminum and a shower of sparks shot out. At least your engines must have gotten high enough to avoid that result!

Not surprising... the flame from burning rocket engines is EXTREMELY hot... couple thousand degrees at the propellant face where the combustion is actually taking place, which is about as hot as a blowtorch-- quite capable of cutting steel...

Aluminum melts at a MUCH lower temperature. If your flame deflector was aluminum, especially THIN aluminum, then even a normal launch could possibly burn a hole in it, or at least distort it... THICKER aluminum could hold up a LITTLE longer, but not a whole lot... steel is MUCH more heat-resistant, has a much higher melting temperature, and of course the thicker it is, the more heat it can absorb before it starts to melt or distort...

However, you are correct, in that the best "solution" to prevent burn-throughs is distance-- give time for the jet of extremely hot gases coming from the rocket nozzle time to expand, and of course as a gas expands, it cools. Plus, turbulence in the flow starts to mix cooler gases and hotter gases, cooling them as a whole...

I remember reading a story that years ago some company sent a salesman to Estes to try to get them to switch from using the mild steel (low-carbon steel) blast deflector plates they were currently using to their product instead, which was touted as a "heat resistant" steel alloy (at of course much higher price). They did an experiment to show the "superiority" of their product to convince Estes to switch, by taping a rocket motor to a stick and igniting it, holding it in close proximity to their "heat resistant" blast deflector... it had a hole burned through it...

Needless to say they didn't switch... the salesman packed up and left...

Later! OL JR :)
 
(Chumlee voice on) A W E S O M E !!! (Chumlee voice off)

So, is this a new kit you're working on, or just something you're playing around with??

Very cool, either way...

Later! OL JR :)
 
Just one of my personal birds, not a new kit.

There is, however, a new kit in the works- so be prepared for a beta next month. Two of the three videos that I shot on Sunday were for that upcoming kit... it is small, will be an inexpensive easy-build that flies great. It can fly on one, or three engines. It will be released with another video. I still have several slo-moes to shoot of it, however.
 
this will be COOL!

Sounds good... looking forward to it... :)

PS. Rick's right... this WILL be cool!
 
Majordude: It was one A8-3 and 4 squibs, which I make myself for FX purposes.
