- LDRS 38 in Argonia KS.
2 Stage flight.
Booster CTI M1540 IMax
Stratologger CF and EggFinder TX GPS
66” Spherechute main with Jollylogic Chute Release set at 1000’ with 24” drogue.
Sustainer CTI M1230 IMax
Raven Gen 4 Primary main and drogue with channel 3 for separation charge set at 1 sec after booster burnout, channel 4 handling staging and sustainer ignition. 84” Spherechute main at 900’ and 18” Spherechute drogue. Stratologger CF for backup drogue and main duties. Featherweight GPS in nose cone.
Onboard RunCam2 and Mobius mini camera. Video editing done in RaceRender and iMovie.
That's insane how fast the speed climbs when that booster kicks in and I can only imagine what the g forces were.
Could be one single tree in that entire field, and the rocket will always find it.. Awesome Video!
NewJerseyJay no doubt.
isnt that the charlie brown syndrome with the kite ?
That acceleration is incredible. No human would be able to stand the G force.
My Coal this is an amateur missile 😂
It literally found the only trees in all of Kansas and then landed in them.
It’s super interesting how it rotates one way on launch then as it’s breaks the sound barrier it starts to spin the other way.
No it spins the other way before mach 1
Launch from on top of Mt Everest and get a 29,000 ft elevation head start. No trees around there either.
Awesome video, congratulations
The easiest way probably
Metric conversions:
Final altitude: 8698.66m
Maximum speed: 572.9m/s
Seems a lot of the deceleration was due to atmospheric drag.
I know about trees. When I was a kid I flew homemade balsa gliders and would often find the only branch in the only tree around.
That first pop was a sonic boom.
Outstanding job !!!! Thanks for sharing.
KLOUDbusters always host a good event. Great flight!
Same here man. Always end up in the trees. Great launch!
Wow want a flight totally awsome hope your ther in sept i would love to see it.. clear skies my friend
Nice launch, nice video, nice job
Great vid thanks 🙏
Thanks for posting
BRILLIANT BRO
In thrust we trust
Nice flight
Отличный запуск...!!!
Nice flight.
Great job! Yes there can only be one tree and...
At least the trees cushioned the impact LOL 😂
Interesting pre-flight build-up, and then the launch: a row of motor vehicles...and a porta-potty.
Can you provide more technical details? Altimeter(s), air starts, cameras, etc...? How did you get the nifty display on the video? This was an awesome flight. I was there.
Zeke Johnson Hey there and thanks. I added more details to the description that should cover your questions. If you have any more specific ones, let me know and I’ll be happy to answer.
awesome! I'm working on a smaller (J to I) two stage now
2-stagers are 🔥! Ping me here once you get it off the ground. Good luck!
Y’all see now the earth is wobbly!
camera gopro make eart to look round
Nice video! Too bad about the spin, but I'm sure its really hard to control since its impossible to get the fins *PERFECT*. I was there on Saturday. I was going to stay for Sunday and Monday but a sick kid in the middle of the night changed my plans... which day was this one launched?
Family White TV Thanks! This was from Friday afternoon.
Tree finder: engage!
SWEET! Crazy spin though. How do you counteract that? Couple gyroscopes maybe?
I used to do homemade Este's C,D, and E's back when I was a kid. This looks like a boatload more fun!!!
The rocket is the gyro, rockets that don't spin at all tend to make arcing flights because of small drag asymmetries. Fortunately, most rockets spin on their own because they have low longitudinal stability.
Stuart Marshall it’s a shame that there was so much rotational speed to prevent a better view. Do you know why the change in rotation? Initial spin wasn’t so bad, but then it changed direction at a faster rate.
@@Ftw9195 I'm guessing that the two sets of fins were initially canceling each other's rolling force until the booster stages. Watch for the roll to switch direction when it looses that second set of fins.
Argonia not windy!? Whoa!
Круто👍
Nice flight. I would think you guys would want some type of remote for flight to keep it straight. Maybe add some side wings, with remote control? And a camera with no fish eye effect. Good luck on next one.
nah, a gyro controlling the roll rate of the rocket would be the way to go, but idk what the various orgs think about guided rockets.
@@chrismofer Guided rockets are illegal... you have to go out to sea to fire a guided rocket... a bunch in Europe did this, look for their video.
So da erf really does rotate @ 1000mph then!
♥Hallelujah and praise, Hallelujah great
Trees have natural tractor beams to draw rockets to them.
Sweeet!
Our test rocket- thevTrc-450 achieved an altitide of 37,067 ft and drifted 4 miles with a parachute. We found the rocket stuck in tjenmudd of a cow pasture.
Amazing flight 🚀I’m trying to make a two stage rocket too, how does the staging works ?
What is the vertical distance traveled, what type of driving motor did he use, and how much did he weigh
That's awesome, to bad they couldn't control the spinning during the launch phase. Maybe have little control surfaces on the fins.....
The spinning actually helps.
The spinning is the control
Why did it start spinning in opposite direction?
What was the distance of the landing from the launch site?
Awesome effort, telemetry, and documentation!
Thanks! It landed roughly 1.5 miles from the pad. Not too bad.
Can I ask what you’re using to get that telemetry data onscreen?
Did you need clearance from the FAA to do this launch? It would get into their airspace.
Yes I did. Would be outrageously dumb to do something like this without clearance and confirmation of clear skies overhead.
How far was the landing point from the take-off point? I'm just curious.
It was about 1.5 miles
Is it supposed to spin like that?
I think it's from upper atmospheric winds.
This rocket could be a great anti air defense with that kind of speed.
4:01 - what he says?) creepy whisper
I seen one rocket a guy did hit the fermanet it was going fast and dunk it stopped like right now. Type in rocket hits dome ypu will find it.
Its is sugar rocket??? Or HTPB??
Hey there - Its HTPB/composite. Actually commercial CTI motors. The designations are in the video description. Thanks
Why not make the camera face the sky?
Because that would be a boring view. Having the ground in view shows how the altitude of the rocket changes.
Because what would be the point of that? What is there to see that we can’t already see?
Agreed. The ground is cool. 🚀🚀🚀
Cool. So it is flat then.
The Earth is flat, I knew it.
Awesome video, thank you.
A chainsaw is part of the recovery system/equipment then.
The flight controllers on drones and planes have a gyro why is no one using similar type tech to stop the spin?
People are using them. I just haven’t thus far. Getting the canards sized appropriately and designed in a way to handle the extreme changes in acceleration and velocity is daunting to me but I intend to start working on a module in the future. This sustainer has always spun more than others. I’ve suspected some slight imbalance in fin beveling somewhere, and I’ve investigated it a lot but haven’t been able to solve the problem. A side effect of the spinning has been that it flies very straight fwiw but kills the camera work.
Here is someone I know that had done tons of stabilization work.

Hey Doc... what is the word/phrase to describe the moment when the rocket reverses it spin ?
Better to use two chute . None will spin
Almost 29,000 feet. About as high as commercial airliners fly. Of course, they should've been warned by the FAA for violating US airspace
And higher than many other aircraft fly. The FAA was of course warned, a permit procured and airspace cleared.
Trees reduce damage..until retrieval 🤣
03:56: What is the source of this click? Is it the hit to the sky shell?)
chute deploy
Someone did not glue a fin on straight.
Wdym?
I still contend it’s an uneven bevel of one of the leading edges.
Hey! It didn't hit the dome!!!
🤯
There is no dome.
Because there isn't one.
No shit Sherlock. Sarcasm much?
28,530*
Škoda že tak rotovala při tom startu...
Fish ie
Kansas ,~~~the Land of Ahh's !

wow look at how glat it looks down there - no curve
Hold a ruler up to the horizon. The curvature is clearly visible.
@@Hobbes746 dont be so stupid - the horizon is flat even your Neil De grassi will tell ya that .. dumbo
@@melvinp1324 Go do the experiment before making false claims.
@@Hobbes746 go work out what feet and sea level is before being a mong !!! you dobt measure curve in any of the 2 ,, you dumbos need to go back too school and not the indoctrination 1
@@melvinp1324 Tyson was wrong when he said that. Actual studies show that humans can see Earth’s curvature with the naked eye at any altitude above 10 km.
If you hold a ruler up to the horizon, you can see it at sea level.
We can confirm this by doing a geodetic survey: every piece of seemingly-flat land is curved, so are all bodies of water.
Sea level is a spherical surface.
Hey was wondering if you could help me with a problem I have. There is no one around me in Illinois to help me haha. I kinda scratch build rockets and I wanna build a rocket that is 10 feet tall and can run any where from 1 -10 motors i just need help i wanna impress my folks can you help me come up with a design I bet my mom a 100$ that I can build a rocket that like 10 feet tall another thing to mention is that I have the electronics as in altimeters and a electronics bay already build from a previous rocket that would work with a 4.00 INCH diameter. So do you have any ideas I have all the explosive charges to handle the parachute being blown out and such do not worry bout that. but yeah could you help possibly.???
Flerther: Fake fish eye CGI by NASA shills!
Normal person: Cool rocket bro!
Us nerds: Good apogee for an amateur launch!
The earth is Flat
Get back on the short school bus. This isn't your stop.
So the earth is really flat..
So. You're an idiot.
Flat earth
Idiot
FAT Earth
Fail. That death spin was totally preventable. Unwatchable
Lol okay.
Can't wait for gbakers rocket footage
@@awatt please. Hold your breath

So you are just another Internet blow hard. Good to know
