The gear ratio of one pair of gears is 1:5, and 5x5x5 is 125, so the ratio is 1:125. It looked like you were spinning it at about 2 times a second at top speed, or 120 rpm, so the speed on the propeller is about 15,000 rpm, or 250 rotations per second!
I work at an aviation museum and something a lot of people don’t understand is that a 4 bladed propeller actually has more drag than a 3 bladed propeller so the thrust benefit is outweighed by the drag unless you have it going at very high rpm.
Regarding the rather large prop, you could fix the skipping problem by adding one or two more 24 tooth gears on top of the first one. This should allow it to raise the axel out of the bar while still being powered, and then actually fly.
@@LachlanHoran-xw7qz if he did it would be 216 times faster, for gear ratios it would be 6x6x6 not 6x3, it’s a little complicated, and 40/8 is 5 so it is 1:5, I think
Have you ever made a working trebuchet? The mechanics of it are complicated enough that it's interesting, but not so complex that it takes a degree or even much effort to learn them. A friend and I made one. Eventually we got it optimized (our swing am at the bucket side was too long) and was able to send a rock clear across our huge kitchen. If you haven't done a video like that, I suspect it would be interesting.
I love the Airjitzu sets. My friend had the Morro one back in 2015 and just recently I got pieces to rebuild my Kai one. Update: pieces shipped and now I can’t put down the flyer
The issue you're facing is that the lift you're getting is causing the gears to keep disengaging, so the propeller slows down, losing lift and dropping the propeller back down onto the gears. you need a way of rotating the propeller's axle that doesn't disengage from the gear train while still allowing the propeller to gain height.
My little guess is that what you want isn’t light weight, but low efficiency. It sounds contradictory to normal logic, but hear me out; the propeller needs to build up some speed to actually fly up when taking off, and if it’s too efficient, it’ll flop out before having had enough time to get that momentum going. Plus, more mass = more innertia = slower descelleration = longer flight time (hopefully).
3:50 when you slow it down you can see that the turning motion also jerked the propeller end up and it looks like it knocked it into the air instead of it getting lift… I think a future video where the launcher is stationary or locked down would be a better test
100% you definently need to give yourself a longer handle and a bigger crank just to hold it way more firm instead of pinching two plates together while rotating a single lego peice with no handle that could definently help alone
Makes me remember about the toys back then where you had a spiraled stick and a propeller you would push the propeller as strong as you can and it always flew hella high pretty nostalgic
I did the same with 2 buggy motors and in a specific configuration the propellers managed to hit the ceiling of the room. If the gear ratio gets too high it wont work properly due to limited motor power and friction
This reminds me of the nostalgia of the circuit game there’s a little fan and he had to connect to the battery box so it can get the fan working and it will eventually fall off
dude i used to make that 3 blade propeller with a wind up motor an with a technic wheel to make it easier to twiest and it went flying sorry i ment 2 blade
It was the light reflecting on it, the plastic isn’ like metal with its properties so it cant make a spark. If it was, im glad this guy didn’ burn his house
I got a prop that was on a big boat or something but I did that and it works much better then yours im talking 20-25 meters but I used a rope around a stick glued to it to propel it

If the propeller was thinner, would it have less drag or not be able to fly?
@ depends on how much thinner

airjistzu ripcord, used it when i built beyblades

2:02 the gear speed is 18 times faster than rotating the handle
I disagree because 5x5x5 is 125, meaning it would be 125 times faster, but if I’m wrong let me know.
@@RC.Bricks I remember hearing early in the video he said 6 times faster

Lego pieces can also make people fly, when they step on one
In my basement😃
No, It won't make you fly
Lol
most likely will make you trip and fall
@@theconsoleintheclosetit’s a joke blud
if you use 2 gears on top of each other and another set of gears stacked it gives it more Tork solving your problem pf harder to crank.

For the rip coord I don't think there are any but ik that in set 42152 it has a mechanism that might work

i love it
Great video i wish someone will someday make an actual flying lego plane :D
While this is cool, it already exists. The Lego Bionicle line featured a disk launcher with a ripcord mechanism.
I loved those 9:20 they were something special 😂
SUGGESTION:Make the axle longer so that it has more time to spin: it will fly better
Kinda like a guide that will guide it upwards until it flies
Naaaaaakkkkkkhhhhhh
8:17 theres some in lego spike set
Lego engineers inventing the rhotuka launcher from bionicle
10:00 hey, I have that propeller to it’s in my Lego box🎉
Nice

Use the bayblade loncher up side down
This channel never fails to impress me!
Can u make the longest lego train or make a train that is all sets in one
Cool Legos

Should make it powered by one of those "pull back to wind up" car motors
8:18 you could use the ninjago rip cords
cool video bro 🤙👍
I did the same with 2 buggy motors and in a specific configuration the propellers managed to hit the ceiling of the room. If the gear ratio gets too high it wont work properly due to limited motor power and friction
I have one compatible with gears
It’s the Old Lego red NinjaGo BayBlsde set just like yours but in red
Metal fight launchers are compatabel with lego gears 8:16
City update?
Yessss
Do you mean Gtag?
I remember doing that with those tiny drink umbrellas when I was little I would have fun doing that for a while.
Great video man
Thanks!
good job and i love your videos like your wind turbine one that you made
Bro acttualy explained gerar ratio in 5 secs
Lego Ninjago airjitzu flyers😂😂
1:04 could you use this technique to make a friction motor and make a friction motor powered toy car thing??
Probably
10:32 bro is a professional upstairs and downstairs neighbor
Reminds me of the 2005 bionacle spinning propeller disc. Exact same concept
THERES NO WAY THAT WAS 2015!!!! ITS ALMOST BEEN 10 YEARS?!!?! I REMEMBER WHEN THAT CAME OUT LIKE YESTERDAY! I REMEMBER THAT ENTIRE SEASON OF NINJAGO!
This reminds me of the nostalgia of the circuit game there’s a little fan and he had to connect to the battery box so it can get the fan working and it will eventually fall off
Just saying that small propellor is meant for water so its kinda unfair for it
Yeah, but I just wanted to try it anyway.
@@brickstudiosYT fair enough, but still, you should try it submerged
Can you try launching wheel on water to see which one can roll on it
W vid
Almost as many revolutions per minute as France!
I can't
You know how I have a Lego helicopter and a real flying Lego helicopter
8:32 u can make your own ripcord you just might have to super glue it so it doesnt combust in your face like it did to me once
now adjust it to make a vortex in water
Bro just made beyblades with legos💀
Try to use the ripcord to make the original design spin
Airjitzu used a ripcord compatible with the black gears
shouldve used a string instead of a lever so u can oull the tring and use ur whole arm to spin it instead of just ur hand
If this works it starts Lego Beyblade’s
You are BEST
Use Pullback motors
love ur intro
4:08 the propeler is wrong way
Rc bricks the calculator😂🎉🎉🎉🎉🎉🎉
10:16 You had to click it in (more than you did).
I also made one fly
You should of used the city flying helicopters
try it with lego motors
Bro, the Lego gear tiles 8:22
who is bro like uh brother you’re all alone 😂
I had some of the bade blade lego set that was made in 2015
could've used a pull-back engine
Beyblade made out of lego
8:04 I know what you mean😊
Try with a friction motor and
Lego bayblade spinner😂
Air raid siren
Lego Airjitzu flyers can fly
@annalloyd9939 NO ONE CARES THAT UR FIRST
anyways nice video
The Ninjago spinjitzu sets.
Have ripcorde
Bro same thing with me for that lego set
❤❤❤❤❤❤❤❤❤
Make it ×50 speed of you cranking and see wat happens
It's already x125
what would happen if you added a fourth 40 tooth gear?
It would be so hard to turn I could probably barely or not even turn it.
@@brickstudiosYT thanks for letting me know before ordering the peices to make my own.
or what about attatching multiple lego motors and see if they could turn it.
@@bkb415 I'm not sure if the motors would be strong enough.
dude i used to make that 3 blade propeller with a wind up motor an with a technic wheel to make it easier to twiest and it went flying sorry i ment 2 blade
1:56 I saw a spark
It was the light reflecting on it, the plastic isn’ like metal with its properties so it cant make a spark. If it was, im glad this guy didn’ burn his house
Take this device and add a motor so you can make a helicopter
Use a motor!
A death machine
Ratuka spinner exists....
I have a few but other colors 9:11
Wait, 9/11????
Peter sripol made an rc plane out of lego
Whats rpm
Already did that
