Suggestion, place Ripstop material between the fins. That will substantially increase your surface area in free fall.

I dont think he's looking for a parachute concept. I'd be in favor of longer blades attached to a rotating hub utilizing a gyrocopter concept. Maybe two of them counterrotating. ...and maybe a solenoid deployment mechanism.

[@blaircox1589]

But cool to try. Even a mesh, just to slow descent. If they are on servos too that auto adjusted. Would be neat if there were a simulator to try this stuff on. Something fairly accessible and not requiring compsci degree.

Use 1 servo to pull all the fins out at once.

[@jacobellis8135]

Brilliant!

[@wondamaner]

The airfoil affects of the steering elements is causing drag in horizontal attitude in the vertical direction. I.e. they are acting like an empennage and keeping the back from dropping. Any form of "flying" drag is going to have a dramatic affect on gravity effects.

[@DSB1234567890]

I think the servo fins are reinforcing the spinning on the way down. They're adjusting themselves in a way that would stop the rotation if air were going downwards through them, but air is going upwards instead so their effect is reversed. Like you said, it would be interesting to have their control loops reverse on freefall but that would be tricky. Maybe have it reverse when throttle is near-zero and a certain rate of descent is measured (GPS or altimeter)?

[@lycantrophe2]

When you said it looks like a helicopter i thought "actually.. why not make the fins from helicopter blades so the rocket can descend with autorotation like a helicopter. the rotation will also gyroscopicly stabilize it.

[@jamesg7371]

Put the hinged flaps on a ball bearing or what not to get the rotation.

[@pauljs75]

Rotor rocket descent isn't exactly a new concept, but I agree it's worth visiting. If you're intentionally having it helicopter on the way down, then the rotor section needs to be able to spin freely so the rest of the rocket doesn't spin with it. Mainly because it'd make regaining control a bit easier. Might even be more stable because a bit of the gyro effect and the spinning would make the fins deploy more consistently.

[@blaircox1589]

@@jamesg7371 yes, that!

[@TheScreamingFrog916]

Make the flaps slightly angled, like fan blades, and spinning centrifugal force will get them all to stick out on the way down. or use a servo to push a ring up under them, a little like an umbrella. When only one flap sticks out, it makes it less likely that the others will deploy because of aerodynamics.

[@djedUVprojector]

I also thought this was going to use autorotation principle, how about mesh petal shaped curved fins...

[@toreshammerecelt861]

Nice to see smart young people with wholesome hobbies. 👌🏻 God bless.

[@testbenchdude]

You probably already know this, but the motor scream is due to the prop's proximity to your vectoring surfaces. I mean, it's not a big deal aerodynamically, but that's the reason that flying wings (in pusher format) and prop-in-slot motor placements are so noisy. I'm not sure there's much you can do about it in this config, but there you go. Neat project, and thanks for the update!

[@BrianPhillipsRC]

[@Stanton_High]

You need better props BAD! The vectoring is flattening out that 5x3x2 to make almost no thrust. Get something like a 5051, dal cyclone 5050x3, or emax avan and this will be a whole new beast!

[@friendlyfire01]

My 2C is to disable control surfaces and center them when the motor is shutdown, all as one. That way the top fins should provide the most drag and corrective forces. This will also keep your motor pointing down and lessen the altitude it takes to arrest your descent.

[@friendlyfire01]

OH! also the top fins should fold slightly more than 90 degrees to the body because when the craft angles hard over the opposing fin must be able to match that or else lose efficiency. when the craft is vertical, the fins all facing slightly toward the sky will increase descent speed slightly, but the benefit is massively increased centering on descent. KSP FTW!!!

[@NatEva]

Have you considered integrating a way to move the battery up and down the shaft to dynamically adjust the CG? It may help you solve the CG/CP relationship in the different flight modes.

[@AirCommandRockets]

It's amazing how quickly it pulls out of a spin on the way down.

[@carlocastelli7511]

If it's not already been suggested you could color the drag fins to help increase visibility to help with orientation.

[@TheScreamingFrog916]

florescent orange on the bottom, with reflective tips

[@josiahR125]

may i suggest colouring the fins 4 different bright colours to help get its orientation

[@jamesmontgomery6304]

Excellent project! Once initial thrust is cut off, and free fall is initiated, I was watching the lower fins move, and initially thought it was surface "control flutter." It seems (like you mentioned) that the gyro was trying to compensate (albeit backwards) to return to equilibrium. It was interesting to watch the rocket pitch as both sets of fins fought for more drag. After the CG was lowered, the rocket simply spun on a stable axis. You could orientate the upper fins to take advantage of this, perhaps a controlled helicopter - like auto gyro descent, like is mentioned in a few responses. Trying to program the lower fins to compensate in a reversed manner solely during free fall would be really to cool to play with and observe. Also, battery in a higher position during launch and lowered for free fall? Once again, great job stretching our access to the frontier of this kind of stuff!

[@BillGriggs]

Cool project. I wonder if larger fins set at a higher angle of attack could induce a more controlled spin?

[@FPVREVIEWS]

Need to eject a battery after ascent, then use another for landing, to change the CG/CP balance? better to orient the fins in the vertical plane, rather than horizontal, so that they can stabilize better, such as grid fins(which are oriented vertically in an aerodynamic sense, but horizontal appearance) , or arrow feathers. looking forward to seeing future developments.

[@problemwithauthority]

Very cool. First mod I thought of was to have the upper stabilizer use longer blades like a helicopter, and have the blade hub free spin on the shaft....giving a an "auto rotation" effect where it will slow the decent and offer stability...Stubby blades may work as well.

[@tonystanton9223]

Just came across this and was instantly amazed at what you have built, first one ive seen, love the idea, i see everyones comments on the flaps at the top and i thought id add my 2 cents, if you angle them slightly as in a a set of multi rotor blades , one set clockwise the other counter clockwise , it mite stabilize your free fall, also just some food for thought, when you spoke about how sensitive your cg was, i had an idea, since your main centre structure, why not wind a coil of copper wire around it and slip a magnatised steel tube or a magnet with a hole in the centre over the coil, so it can slip up and down the shaft, with some way of varying an electrical current through the coil , you should be able to move the magnet up and down the shaft, i understand this is more complicated than it sounds but its a starting point for the idea, with some software involved it could be auto set to move itself depending on acending or decending , or you could manually move it with a trim knob on your transmitter. Sorry about the long read, love the idea man, cant wait to see where this leads 👍👍👍👍👍👍

And cheers 🍻

[@jaymassengill3340]

If you make the thrust vector control fins symmetrical from top to bottom around their axis of rotation, that should reduce the deflection caused by the upward airflow across the fins when the vehicle is falling. It looks like that upward airflow when in freefall is overpowering the servos.

[@acadman4322]

you should find middle balance point, add servo on switch or timer and add small parachute. large project but it would be fun to see it land on its side slow and controlled. im interested in how you would strap/deloy such things from the side. easier from a top mount cap.

[@zalmez7207]

[@melloowrush]

This is very interesting! I would love to build something like this. I think the reason its spinning, which starts right after you reduce the throttle, is because like u said the servos are programmed to control air coming from the other direction, so when air hits it from the bottom the servos move to exaggerate any rotation, like the rotational torque from the motor spinning down

[@nathanchalecki4842]

The backward acting control surfaces definitely mess things up while it's falling. Would love to see that fixed. Cool project!!!

That sudden decelleration was aided by ground effect of the thrust pushing against the ground as it approached.

[@PokerShark101]

Great project... Reminds me of something was working on a few years back but didn't get to finish. It also reminded me of an interesting effect I noticed when I was a kid. I had one of those balsa wood cheapie flyers with the red prop and rubber band. Just for kicks, I removed the rubber band and gave it a toss. Much to my surprise, the air resistance caused to prop to spin fast enough so that it was having an interesting reaction to the flight characteristics of the plane. When I'm watching your rocket fall, I'm wondering what kind of an effect would be created if your fins were shaped like props, and they had the ability to spin with wind resistance during free fall. My guess is that the gyroscopic effect would add some position stability, while at the same time increasing the rockets hang time as it falls.

[@WForrestFrantz]

Really great try-storming. The more naturally stable the ship (as you found by moving the battery down), the more thrust that can go to missile lift acceleration/speed. - Put the motor at the top (out of the way of the battery). - Put the battery at the bottom ... looks like you know how to print a centering bracket/landing legs to hold the battery under the end of the carbon rod/fuselage ... for natural stable vertical flight, the Cg of the battery must be dead under the rod/fuselage or the ship will have a natural lean - That will put the Cg as low as possible so the missile is as stable as possible so thrust goes toward vertical lift - With the props at the top, you no longer need the flip-out fins because ... a slow rotating prop will create a drag disk during descent (more drag than lift) ... the battery mass will keep the ship vertical (think pendulum) ... the rudders (located under the prop near the top) will no longer create an upsetting force - Consider making the battery holder/landing gear into fins or holder/gear/fins Super cool how you can catch the missile and that your missile has that much lateral control. So yes, continue using your clever rudders (just under the prop) so that you can continue to vector the missile laterally upon descent. Explanation of other comments. - Cp, the center of pressure & Cg or the Center of mass or Center of Gravity ... Think of a parachute. A parachute (Cp) needs to be behind (down wind of) the person (mass or Cg) it is trying to safely lower to the ground. ... Think of a rocket. The tail fins (Cp) need to be behind the mass of the rocket (Cg). ... Your Cp will be the battery-holder-drag/landing-gear-drag/(and if needed, tail fins) and the Cg will be about 1/4 of the distance up the missile. You've created a lot of interest. Well done! P.S. By putting the motors at the top and rudders right behind the propwash, you've created a canard used on advanced fighter jets, so be prepared for some interesting tuning of the actuators to attain smooth vertical flight at high speed :-) P.P.S. There would be a long set of wires running from the battery to the motor. You can use 16 to 20 AWG wire for the amps you are pulling. Wire, unlike on ground installations, have not only heat loss but also lose energy by the fact that the motor now has to lift its weight.

[@ericanderson3985]

I think your stabilizer fins are inducing an oscillation because they are angles downward. Much like a circular parachute canopy air builds up inside and causes it to rock back and forth dumping out excess air that's why they have a vent hole at the top angle the fins. upward or putting some holes and them to dump off the excess air.

[@SebastienChedalBornu]

using a vario to start automatiocally below a certain altitude, and as you said invert the fin directions when falling

[@xnoreq]

You should make the top folding propeller bigger and add a mechanism to have each blade unfold properly on descent. Maybe not have it fold completely or something as simple as rubber bands pulling up each blade (just a bit) would help?

[@oisiaa]

What's the max theoretical altitude based on the energy capacity of the battery and the mass of the vehicle? I'd guess somewhere over 20,000 feet.

[@towers3372]

At full throttle on 6S this could probably go for four minutes. It would have to ascend at 80mph to reach 20,000 feet in that amount of time which I don't think it gets anywhere close to

[@iforce2d]

@@towers3372 right, and that tiny prop could not push enough of the thin air to get the lift it needs to get anywhere near 80mph either. Even at 6000 feet the air is already only 80% as dense as at sea level. Then you have the problem that something will overheat. I'd say you'd be very lucky to get past about 4000 feet.

[@kevinattard5514]

If you’re sticking with the air braking fins in the next design, you should try hooking them up to a servo so you can simultaneously control their opening and force them to stay in the open position

[@icyartillery9027]

I know I’m hella late to this but you could hook up a barometric altitude sensor, run a loop testing for the height, and once it starts dropping (say 10 feet below peak), you roll over your code so the servo positions are inverted (say from limit 45°-135° to 135°-45°)

[@mobzi2644]

I'm not rocket engineer but i've seen a lot of video (just to give one example from Scott Manley) and the stabilisation is about center of drag(CD) vs center of gravity (CG).

[@Nanotick1]

If the 4 blades are for air-brakes then drill some holes in them and open 90 deg. or a little more. If the 4 blades are for gyro rotation then make all four of them longer and all four rotate together but independent from the main rocket body while still being able to control the rocket with the lower fins.

[@GorgeousCorvus]

Love your style and approach!

[@Mobimanie]

You should try to disconnect the upper wings from the chassis, so they can spin independently from the body. Also enabling them to spread a bit higher than in horizontal position when extracted could help to stabilize. I think anyhow your gyro with the control surfaces is messing with it on its way down.

[@leotard2536]

On that last flight, you can see that the vectoring fins are shifting around during the fall, which made it lose stability. If you had a way to change the mode of those fins during fall, like with a button, then it would work better. Also, the pop-up fins would help the rocket come out of a horizontal fall because the fins on the skyward facing side would create more drag than the groundward ones.

[@ryanm.191]

Add servos in the rotational axis so that you can control the rocket on decent (just like the grid fins on a falcon)

[@ryanm.191]

S A that can be easily countered. Plus grid fins wouldn’t cause as much drag, which in this case isn’t good

If you want to drop horizontally you could just have some sort of drag device parallel with the centerline.it might look like a + or o from the end. I also think i saw a flight where only 2 flaps deployed, it seemed to fall flatter but may have reduced your control like when you crashed.

[@greyhunter147]

very nice project! 2 suggestion: 1 Allow the fins go up of more 30/40°, this give more stability (little less drag) and dont let then to close when it inclines 2 put 4 more servo on the fins to push it a little down (increasing drag), you can control the descend with it like aileron and elevator.

[@thoongchinglee4905]

Add some soft thin plastic sheets in between the flaps, when expanded you will have a better drag when the rocket is descending.

Awesome! what software are you running on the flight controller?

[@dwarkabaron8773]

Place light tension springs on the nose flaps to remove the involuntary movement. Adding sight radius to the flaps will add control and more drag for the descent, less drag for the ascent, and a more true parachute effect. You could even place a through rod inside the main tube connected to the speed control which will tell the servo to open the flaps under a need speed/fall condition.

[@MichaelGarrison93]

What if you designed your own type of grid fin like SpaceX uses? They could either be 3D printed or made out of aluminum. Instead of just adding drag and acting like a knuckleball, it would direct the airflow and stabilize the rocket. You could also use servos to control said grid fins to help counter the thrust vectoring fins
