Brushless R/C ROCKET Vertical Landing SpaceX Style - RCTESTFLIGHT

[@TomStantonEngineering]

Nice one Daniel! Cool to see the small props in the top working so well to simulate the gas thrusters. It will be interesting to see how grid fins would work with this design, if you choose to test them. Just a shame these mini quad motors/props hate to be ducted. I think the setup I used was measured at 1.5kg of thrust, but could only just lift the 400g 'rocket' at full throttle. Look forward to the next one!!

[@rctestflight]

Thanks Tom! And thanks for the inspiration! My next design uses a gimbaling motor on the top for attitude control, but I would like to experiment with grid fins/thruster motors again in the future. The duct inefficiency is indeed a bummer. I might try a profile body with my next one. Won't look amazing but oh well.

[@RCLoversan]

Ducting those propellers is not a great idea, because the motor loses a lot of thrust. Using this design you can't even add a proper solid fuel model rocket engine. As a result, you create something that is definitely not a rocket. Please take a look at my Rocket Drone... ready to be 3D printed (having some funds).

[@Specter0420]

Did you guys ever consider using a proper Electric Ducted Fan? I know they are heavier, require more RPMs, and may provide less static thrust than a naked prop but, you are putting a prop in a tube on an electric motor. That is what they are designed for. Something the size you will need is 3D printable. There is plenty online about making them. Incorporating a proper airfoil duct could help with natural stability too.

[@RCLoversan]

@@Specter0420 Being a "rocket" (even if in this case there isn't any combustion of its content), I believe that keeping an eye on weight, should be a priority. Therefore, the ducted fan motors are not the best choise (in my humble opinion).

[@rctestflight]

@@Specter0420 I think there would still be a large efficiency loss from sucking a ton of air through a tube with lots of drag in it (batteries, servos, wires, structure, etc).

Interesting aircraft, you completed what i wanted to have when daydreaming😂

[@JakeBiddlecome]

This is the most stable prop 'rocket' i've seen yet. At first I thought there must be a string running up through the tube in the first trials. Really nice work.

[@bobhawkey3783]

Just a thought - and trust me, I have no idea what I'm talking about - what if you had a threaded rod with a weight on it that could be moved up and down to change the cg just by spinning the rod. This stuff is so cool. Love your videos, great work.

Why would a person's age matter?

[@mccc4559]

@@AtlantaTerry My apologies.....it was not my intention to make it an "age thing." I received your message and read my comment again......now it is obvious how my original comment can be misunderstood. Please allow me to explain for my sake and out of respect for you. You see, I've been fortunate to have been learning from this young man since he was just a young boy. Over the years he has matured into quite a gentleman with an incredible future. My message above was meant as a compliment (for example "I am proud of you) but I didn't want to make it sound like I am writing to a little boy....so I stated "you're older...." The point is that I should have clarified and written something along the lines of "you have aged quickly yet gracefully over the years with such wisdom and sincerity....if I say I am proud of you then it is intended in a very mature way" instead of when you say it to a very young person...where it is intended more as a "good job kiddo".....I hope this clarified things a little for you.....maybe you're his dad or uncle or relative..... I hope you will reply.

[@scottsarchitecturehildebra1761]

Absolutely fantastic, thanks!!!

[@AClarke2007]

Try having two thrust motors in the Tube (one at each end), but at the top use Ducts to control the vacuum entering. Similar to having Thrusters, just in reverse (hopefully, no one will notice the direction of air). Possibly use compressed air too, initially, to save on Battery. Also, make a shroud out of thin batteries to go around the main tube.

[@NickRehmcontent]

Oh my god I was hoping you would show the old yellow thing hahahaha. It's crazy how far you've come and that you're still goofing off. I must say I spent a lot of my early RC years trying to keep up with you and the crazy shit you did like that giant cargo plane or the delta yak

[@NickRehmcontent]

Also, you may want to consider skinning a frame with some door screen type material and painting over that. You still get the looks but probably get about twice the airflow into the motors

[@findmeinhawaii4782]

Great effort and attempts! If you don't mind me being a critic and offering some suggestions here are my thoughts. I think most of the power (a lot) should come from the top of the rocket as if you were pulling an umbrella by its tip upward. Let the bottom sort of dangle with less power during flight. Just enough for control and balance to keep it steady. But upon landing and your approach to the ground, use the bottom engines at full power to cushion and reduce the speed of the fall to a soft landing. Good luck! Aloha Ken

[@stevenclarke804]

Ive been watching you make and fly stuff for many years, you are a smart young man, its refreshing to see young minds working, and experimenting, and having fun with Imagineering, keep it up you'll go far in life!

[@birdseyeview1543]

I daresay it worked a bit better than Tom's version, very well done sir!

[@AddyOverbeeke]

Try replacing the prop/motors with EDFs that have outlet nozzle flush to the outside diameter of the fuselage and inlet ducts flush-mounted with openings in the nose cone. You could also use a gyro to stabilize the flight, not the sensor gyros but and actual gyro that has mass enough to keep the fuselage fixed once up to speed before take-off.

[@dmartinnj]

maybe a smaller nose cone in diameter to allow more air inside might help. Very cool idea though, good luck with it dude :)

[@Benth3rdoneth4t]

You should make a hybrid rocket next. Make it go up using an E or G size model rocket motor, and come down using the stabilizing propellers with an A size model rocket motor to slow it down :)

Daniel, IDK if you will see this comment now. But I think you should revisit this making it much bigger with some crazy power that is available right now. It would be sick! Maybe with a counter-rotating duel motor thrust setup and make the body out of a plastic mesh just for aesthetics?

[@macrumpton]

Very nice. Perhaps you could make ribs like a boat cover the whole thing in a very wide mesh fabric which would allow the air resistance for controlled falling (and from a distance look pretty solid), but allow air to come to the prop through the whole body.

[@FlyingBuzzard]

That is awesome.....just gets better and better Daniel

[@danw1955]

I think it would be to your advantage to have ducts for the top stabilizer fans and the intakes for the lower fan, as they would direct the air a lot more efficiently to the fans, rather than just simple cutouts to let the air in. I think you're getting a lot of internal turbulence in the tube that's messing with the overall airflow, using just simple cutouts. If you could lay out something on your computer and then 3D print them, you could fashion the ducts however you wanted. Also if you had ducted fans to start with, to put within the tubes, it would exponentially increase the efficiency. Just a thought. Neat project!!😉👍

[@harshavardhan2168]

Buld spaceshuttle style virtical takoff and glide back safely..or simply tilt rotor crafts...you are dam good at these builds.

[@CradyLab]

[@markgiles8527]

I've never experience "Really Unstable" control of my drones when landing, but okay. Interesting project you have going there. Think long and hard about some ideas on how to use this, you could be on a winner here. Good job! ;)

[@ohutchie]

Damn dude it's crazy how similar this looks to the Starship hops!

[@TurboSunShine]

Nice! Any chance of seeing you use a ducted fan in the next video?

[@rctestflight]

No chance. I think putting a duct fan in the rocket body will still have the same efficiency loss as putting a prop in there

[@droneredneck170]

Awesome stuff man! Now just put a 1st stage rocket on that baby and some fpv gear. Rocket to a few thousand feet, separate the 1st stage (with parachute recovery system) and Fpv your invention home!!😁😁😁😬😬👍👍

[@Unitedstatesian]

Awesome Project! Maybe ditch the outer shell, make a very narrow shell that covers what is needed. Also, instead of the top motors and batteries add fins for some control. The big body will also be more affected by winds. It can be very windy at high altitude (even if it is calm on the ground). That way you can have all the battery weight go towards the bottom motor. I think that with the fins and having the weight a little lower it will be easier to control. Maybe have the width of the fuselage be just big enough to house a Gopro and phone for tracking. Fins will also help slow down and control return without the motor. Also remember that as you go up it gets very cold, the batteries will need to be protected.

[@jedijeremy]

Sweet! Nicely done, Daniel! If I may offer a suggestion: instead of the 3D printed "solid" nose cone, perhaps if you have two flat pieces of foamboard slotted together in an "X" that would give you the side-profile of a nose-cone that you clearly want for verisimilitude, but would allow a lot more air to get through and reduce weight compared to the plastic. I wish I could draw a diagram, I hope you get what I mean.

[@Coltan1989]

@rctestflight @9:40 - When you are talking about the case that body impacts the performance. It's most likely due to the propeller being designed with a shallow pitch, and probably needed something more aggressive. Also you could have increase the number of blades to create a static pressure behind the propeller.

[@19rocket64]

Fantastic stability..cool to see it correcting for torque n p-factor

[@CradyLab]

What about using ducts for the top 4 props to get the air cleanly out of the shell

[@Crazyoldman84]

At 7:20 when it is descending you can hear the differential in thrust needed to bring it to the ground smoothly, one thing that is lacking in the space x footage. It appears the thrust doesn't change until the last 10 feet or some b.s.

[@brundlefly3658]
