Good job. Use a cheaper cfd software. Like simflow. Try their free version. Why didn't you use perpenticular part to the tail fin, "+". Wouldn't that have made your pitch more stable?

Хороший ролик, без всяких заговорщицких предположений и сектантских домыслов.

This is incredible Mike well done

*MADE IN THE USA*

Dear Mike. Very impressive drone. What was the total production cost?

Completely wrong. The hugr heat created seperated the water and steam into Hydrogen and oxygen. H2O. That makes a big big bang. THAT is why there was an explosion not just pressure from expansion.

Absolut hervorragend👍👍👍😀. Meinen Glückwunsch.

Great vid

great job guys!

Fabulous work! Design, building, testing, flying... Will you be selling kit sets of this drone?

Awesome animations and explanation! Thank you very much!

bro this is as fast as a Cessna

I like your South African accent 👌

Тема сисек не раскрыта. Фильм очень поверхностный, на Ютубе есть намного более развёрнутые.

Awesome work and i love the visuals

Interesting project 👍did you try spinners on the props to decrease drag even more?

Please next time go supersonic :) Great work and congratulations

This is just incredible on an engineering scale and on many other levels.

1:15 do you actually project the drone in blender?

Wow that was Awsome and inspiring

absolutely incredible engineering

Custom ESCs? Might cost a lot though but that might allow for putting them in the arms and increase efficiency

Это сделал Горбачёв чтобы разрушить СССР, но в начале сам испугался

Oh wow, I remember that Church. I was at Submarine School late Fall, 1982.

You might pick up a little thrust from dissipating internal heat. It will be very small. The key is to pressurize the interior. That's entirely possible, your static pressure at 400 km/hr is 7600 Pa. Put an 18 mm diameter hole at the center of the nose, which will also help with camera clarity when flying forward. You should be able to get nearly perfect static pressure recovery. The lip on that hole really matters. Look at the lips on turbofan inlets. The main thing is not to have a sharp edge that immediately expands outward internally. The air then flows through your body and ejects out the back through a converging duct at the very back (not along the sides if you can avoid that). If your ESCs are 85% efficient, you'll be dissipating 1350 watts in there. YOW! If you want to hold the air temp rise to 40 C, you'll need 34 grams of air per second, or 28 liters/sec. At 400 km/hr, your ambient stream tube is 2.5 cm^2. Expand that to 25 cm^2 through the ESC section and you'll have 40 km/hr air at almost 7500 Pa. Heat by 40 C on a 20 C day will get you 13% expansion. I can't determine the perfect ejector nozzle diameter, but something about 13% larger than the ambient stream tube should do it. Guess 2.75 cm^2 or 19 mm diameter.

💪🏻💪🏻💪🏻💪🏻💪🏻💪🏻🔥🔥🔥🔥 freaking good vid, content, build👏🏻👏🏻 like like like and a massive highfive!!😊

One degree isn't that much. The main church's steeple where I live has a lean of several degrees since 1654. It has been leaning since it was built, it has been tried to be corrected several times. It surprised me that this rather new steeple collapsed

Beautiful! Congratulations

It was a chemical reaction

There is no neutral setting for props. If you are going to make a video discussing air incidents, make an effort to learn about aviation first.

wow, really amazing engineering.

Amazing work Mike and good video. You need to do more works like this. Keep it up❤

@Mike-Bell do you think you could possibly do a video (or just describe in general here in a comment) on how you go about setting up Blender for precise (down to the millimeter) modeling? How do you go about setting up the environment, did you use any specific Blender add-on's?

Mike this is amazing, congratulations to you and your son for the record. World class work

Besides your world record and your engineering skills … your storytelling is marvellous! Thank you for sharing your design process.

imporessive

Well dome Mike and Luke

I like to know the RPM of the motor at top speed !

That hole won't create drag ?

Things just aren’t going well for religion in the U.S.

and the true MAGIC BULLET is born.
