SpaceX inspired edf rocket part 2: Final assembly, tuning and maiden flight
Ғылым және технология
This is the second part of my Spacex inspired edf rocket project where I assemble the final pieces of the rocket, tune the correct PID values and perform a maiden flight.
In order to find the correct PID values i had to build a rig that suspends the rocket in it's center of gravity and which allows for 2 degrees of freedom. I first tried to tune the PID values with the rocket suspended on a wire but this ended up working not so great like you can see in the video.
Once i got the right PID values dialed in, I first did like 10 hover tests inside (now i did try this out with the wire attached) before going outside to attempt a maiden flight. I build and painted the landing platform a day before the maiden flight and the paint was still a bit sticky. As a result of this the rocket stuck to the landing platform and tipped over. For the next attempt i put some baby powder on the platform to prevent it from sticking (which gave me some nice clouds when taking off ;-)
It turns out landing an orbital rocket booster (RC replica) isn't that easy.Cudos to you mr. Elon Musk ;-) I wanted to do some more test flights to try to stick the landing but unfortunatley the wind started picking up. However I'm still very happy with the results i managed to get out of it (in contradiction to what some people tought ;-)
Once the weather clears out again i will definitely try the landing bit again, I'm even thinking of adding a gps to the pixhawk flight computer and attempt an autonomous landing. We'll see.
For those of you who say an edf is not a rocket, you're right it's technically a single copter design in the shape of a (SpaceX) rocket. An edf really is the easiest and cheapest way to control the thrust to maintain a stable hover.
I wished i had the technology, knowledge and money to attempt to build a liquid fueled one.
I'm referring to "Spacex inspired" because i did use some general proportions from the falcon 9 rocket but had to make a lot of adjustments to turn it into a fully capable working rocket that's capable of hovering.

Great job! FYI I found that iNav was much easier to tune than Arducopter for this sort of thing. I was never able to get my single copter flying well with Ardupilot but iNav was very stable with just a few minutes of tuning.

@rctestflight thanks man, I’ll definitely take a look at iNav, thanks for the tip. Btw i also love you channel, I watched a lot of your videos. You made me want to build a solar plane so bad haha 😂👍

Alexey chekurkov , with your skill in engineering and design you could probably build this guys anti gravity device. Many people have elvaluted his videos and cannot prove them fake. His videos are in Russian but some have transportation and full explanation of theory.
I am seriously impressed! Not only by the result so far but also by your structured approach. Great job!
this is what i want to do in my spare time.
Absolutely incredible! Amazing work.
That's actually amazing! The legs design is beautiful. Waiting for more updates.
Wow!! Huge Respect for your engineering!!
Impressive! And also makes SpaceX all the more impressive 👏👏
he's in the shop again marlene, playin with those damn rockets again!
Very creative and she looks beautiful. Excellent work!
This is absolutely amazing! I've been working on a EDF VTVL vehicle too and really respect your work knowing how challenging this is! The fully functional legs are so satifying! It would be cool if you add some deployable fins on V2 so it can fly up and simulate landing
Love this project. Looking forward to more videos
You are a great inventive constructor with passion and commitment. Don't give up, you'll be great. I'm cheering for you.
You made the world a million times better with this dude, thank you
Absolutely amazing! So much fun watching the hovering falcon 👍🏼
This is brilliant, great job!
I remember when you first started this lol. It’s really cool. I’d recommend putting motors on the side near the top for added stability. Not sure how big of a job that would be coding wise, but it would definitely help for keeping it stable and help during landing.
Wonderful work, absolutely love it!

Thanks Evert, I printed out a new set of thrust vector control fins with a chamfer just like you suggested, they work great now 😉👍
Now that looks awesome!!!
Excellent work so far, never give up! You can do it!
*AMAZING WORK* Thumb up i am just for long time in RC Model Scene but that i have never see befor, very very nice.

Looking great from my rc perspective too, Great thing is you can dial it in, with almost infinate adjustment. Landing geat needs some attention, id temporrly do a rc helecopters trainer style landing gear, till its set up.
Awesome! Great work Brain!
Respect 10/10. That is epic design skills
Ooo I didn't knew you were going to make this thing fly, epic!
I see a future SpaceXer, great job Brian, I was impressed with the gimbal mounted test stand, the rocket blew me away!
Omg I loved the ending trial and errors. Very cool.
Well I really appreciate spacex's struggle seeing your landing struggle with much simpler approach where forces involved are in small scale.
Cant wait to see your progress, subbed!
Awesome work Brian! Really love the design!

Really nice work... To be continued 😊
Awesome and great work!!!
Awesome as always 🔥🔥🔥
Genius !!!!!!!!! If it were easy everyone would make it, It take a special mind and fortitude. Well done Bravo 💪😎
Very cool project!
😍😍😍 yaayyy it flys. Well done, that's amazing
Great job! I will wait for a successful landing
This is awesome Brian - great job. I wished we had found this before our attempted EDF Rocket build video we just posted. We are wanting to get rid of our parachute and go to a VTOL solution in our version 2 so this fantastic to see it's possible. Love your projects
Nice, awesome work.
😎🤞🏼Great work!
excellent video, i really like the little test stand you built. looked very clean and professional.

Damn you are so smart!! Hats off to you man!! Keep doing what your doing we need more brilliant minds like you nowadays!! It would be so cool to see it fly around like a rocket or sidewinder missle then land please do somthing like this in next video!! Well done man!!
Excellent effort and design .Nice work humanity reference.
Interesting idea. Well done :)

The weight needs to be towards the top in order to achieve a stable flight.

Amazing Job!
Really good......we need more people like you.congratulations
Amazing job! Keep making
I come here from un poco de todo,keep it up bro
Nice work! All those landing look so like space x in real life!!
Great project!! Looks great! Add weigh to the lower position or move down the EDF or battery. I fly RC airplane and when the plane is in hover and nose heavy start to oscillate the same way that your booster, so my advice is to add more wight in the lower position or remove weight from the upper position. Good luck!!
Atlast my favourite video for which I was waiting for is out here 😎😎 thankx sir, you are an inspiration for young aerospace engineers 🙏🙏
Great work!
1. Put a rocket engine at bottom. 2. Put landing legs at top of first stage. 3. After burn launch, eject capsule (parachute?) and use small gyro to flip first stage of rocket 180 degrees. 4. Now with landing legs down, use the landing motor to put her down. Piece of cake!
Just popped up on recommended videos. I'm not and RC Rocket guy but that was awesome, congrats on the project 😎👍

it may be bouncing on landing because of the flexiblility on the leg mechanism. Awesome solution for the air intake!!
Great job 👍
Brilliant, well done. It took Spacex a few attempts before they got it right.
Am i the only one who doesnt know anything about this yet i watch it because i find it entertaining?
great video man. already excidet for the next video keep it up😁
Just like with the real thing, I was thinking "This will never work at all". And just like with the real thing... I was wrong. :D Nice work!
When quarantine make you more productive👍
It looks a lot like SpaceX when they were first trying to land a booster. A lot of falling over... They had a lot more explosion. lol. Looks great!
Never give up is the key for success. Keep climbing. 🚀🚀

Keep going, you're almost there! Maybe griffins or engines for lateral thrust

Haha yes, unfortunately grid fins aren't that usefull at low speeds, but using compressed air thrusters might work to keep the rocket upright during landing.
