Teaching a Dremel Tool to Helicopter

[@AsymptoteInverse]

Remember that scene in Apollo 13 where the old lady says "...if they could get a washing machine to fly, my Jimmy could land it." I think Peter is the guy who could get a washing machine to fly.

[@rocketboysmc]

Now Peter must make a plane with a washing machine motor!

[@TravisFabel]

There's your answer. He needs to build it like the lunar lander. Stop trying to make it look like a helicopter and make four large panel legs with the propeller on top. You'll have no directional control but it won't try to tilt Because every time it does the downwash would straighten it back out

[@littlesnowflakepunk855]

all they needed to do was add a rigid bar and another two bearings above the gears. Would have prevented the flex and therefore reduced the gear slippage

[@griptopia]

dual bearing on the input and output shaft for the main rotor, the extra rigidity on those stops gear mesh issues / reduces vibration etc , also make a guard for the spur gear, ask me how i know :) loved this project so so much, brilliant stuff chaps as always

[@rc-fannl7364]

Yeah, I respect the creativity and perseverence, but expecting something with so much vibrations to fly, is like asking for a miracle.

[@griptopia]

@@rc-fannl7364 This is how smart peter is he knows where he can cut corners but, having done similar stuff getting the spinning assembly parts balanced, just makes everything so much easier, rear rotor authority kicks in earlier as well once the vibration is under control.

[@tomclanys]

Yeah I was so surprised that they didn't support the shaft with a second bearing above. It was the main reason for all the vibration and skips

[@stich1960]

He's fighting weight this whole build too though bearings are heavy

[@cessman8054]

I came here to make this same comment, but I’m five months too late sooo .. cheers! 🤣

[@spavliskojr]

Very cool to see a [cordless rotary tool] fly! The final iterations actually sounded like a real full size copter once you got it stable

[@colinmetzger6755]

I think adding another bearing and supporting both sides of the gear would have helped. I think I heard a lot of time where the teeth would separate and the gears would skip.

[@fss1704]

A planetary gear is slmost infinitely better, especially when you have a 3d printer.

[@pauljs75]

So much lost power for the main rotor due to poor driveline engagement. Wasn't the motor's fault. Peter may have given it 110% given all constraints, but 10% more would have had this thing as a complete success.

[@bmxscape]

true that i was thinking it was amazing it sustained flight with basically a slipping clutch

[@saveitforparts]

I'm impressed how much patience you had to keep re-building this when it crashed and broke! I would have set it on fire after about the 3rd or 4th failure!

[@butchgarner3911]

I am so glad that you seem to like sharing the torture you go thru to make these projects! It makes for a hell of a good laugh! Thanks for another great video, Happy New Year!!

[@sane_scientist]

phrase of the day: GYROSCOPIC PROCESSION you need to have a mechanical bias to the flybar that offsets it toward the direction of gravity or else the effects of gyroscopic procession will continue to crash it, thats why it slowly tilts more and more until it crashes every time. i would recommend having the flybar angled down away from the blade to give it leverage and make the tips atleast a quarter the weight of the blades to make it want to self level.

[@drdremd]

I’m no expert, but I feel like improving the gear box would help both power and stability.

[@DeanF]

Yes, it starts the initial imbalance.

[@psychosis7325]

Seems like a flying mower is a must and I feel it needs to still mow to be a total success.

[@simitarknut2201]

The KZbinr, "Night Flyer" was part of the development team that made the Kyosho tail rotorless RC helicopters sold by Tower Hobbies in the late 1980's early 1990's. I believe if you contact him and get some of his data, you might be more successful without a tail rotor, and only throttle for up-down and regular rudder for directional control.

[@JustinKoenigSilica]

He used a big paper plate as a replacement for a tail rotor, works great! You just get no rudder control lol. But you can still Change heading.

[@PilotChris06FW]

The helicopter must always be in forward flight for this to work.

[@RolfRBakke]

The Kyosho HyperFly! My friend had one. It had a no throttle, just a switch on the helicopter that got turned off when the helicopter touched the ground.

[@PilotChris06FW]

@@RolfRBakke Yes I mistakenly got a Hyperfly as my first RC aircraft.....biggest waste of money and a ton of frustration. It was like throwing a bowling ball and expecting it to fly.

[@RolfRBakke]

@@PilotChris06FW Our first flight went straight into the ground as well. We learned that we have to let it climb straight ahead, and turn right. Left turns made it dive. So it kind of worked. Not for the beginner tough...

[@submachine785]

If you try this again I would add a more aerodynamic fuselage witch might reduce the interference from the gears and make it more stable and the damage upon landing

[@blenderbachcgi]

I died when the propeller came loose and flew up! 🤣

[@corvettedoc1]

I would like to see this Dremel revisited as a Gyrocopter and the Dremel being used as the forward propulsion. Then you will have a dihedral to keep it balanced plus rudder authority via the tail planes and still retain a rotor and blades as your lift. Looked fun!

[@bigc2nyce]

for some reason, it really is funny every time that prop flies away without the dremel... lol

[@erik365365365]

I love Sam but I truly love the family dynamics here! So “pure” … pure childish laughter!

[@FilosophicalPharmer]

Serious Question, Peter - did you consider a planetary-gear for main rotor? Seems like it would have two advantages: less flex and weight of tool directly under rotor. Very curious... Thanks!!

[@excelsior8682]

Possible torque loss but that could work

[@fss1704]

That would be way better, for sure.

[@davidmerander576]

That and gyro control would be a winning combo.

[@bradenmolloy7443]

They can create heat when not lubricated simple is better for dry gears

[@ReverendTed]

Isn't it best to have some weight out in front of the rotor shaft in order to counterbalance the weight of the boom and tail? (Just spitballing here.)

[@Sp1der44]

Some things I noticed - a shorter screw in the gears could help remove the centrifugal imbalance which is impeding the gyroscopic stabilization you should be getting from the rotor mast, also adding a guide flange to both sides of your small 3D printed gear will help it maintain the interface with the larger gear and not allow it to have so much play in it. Beyond that - y'all are not only insanely clever, but also extremely good at making entertaining videos.

[@oisiaa]

Good job Peter! This is a video that I read the title, saw the thumbnail and said "YES!" out loud. Immediate watch for me (I'm only 0:03 in to the video and had to post this comment).

[@tombuster]

[@WindCatcherRC]

I think you were fixing and iterating far more than flying. In the end it flew! sorta. That was cool!

[@armysheep75]

By the middle of the video I was fully resigned to assuming it would never fly. This would have been fine, because the laughs and goofy enjoyment was definately contagious... great video.

[@ChrisHarmon1]

I made my own set of piccolo blades back in the early 2000s. I later made some collective pitch blades with symmetrical profile and just put a tapered shim under them to give a fixed "collective" like pitch and they flew extremely well. I dared not try them before static/dynamic balance which doesn't take long.

I don't know if there's a free plug-in to make them, but helical gears would give you much less noise. Involute gears are good for low speed high torque applications. Things I've learned from This Old Tony.

[@2testtest2]

There are free plugins for fusion for helical gears. I'm not sure they would be a good fit for this application though, as they also create a side load, which would case the frame and gears to flex depending on how much torque is applied, possibly causing them to disengage in flight. By involute gears I'm assuming you mean straight cut gears? Involute gears can be straight or helical, and is the most common type in machinery today, and are suitable for all speed ranges.

Think about a pneumatic torque wrench powering a go-cart. The fun would be the air compressor needed to keep the torque wrench moving. If you wanted to scale up, there are torque wrenches in 1-1/2" and 2-1/2", if 1" is too small. Problem is scaling down as the CFM doesn't change that much.

flying without cyclical control would be impossible. Youll lose lift when it wobbles or picks up to much speed. You need counter rotating blade to have any chance of that.

[@QuinnShaw]

This was awesome to watch. Knowing how long it takes just to make a new blade... I was kind of blown away by how much time went into this. That being said, you guys need to cool your jets when it comes to testing and not test it in an enclosed room with random hazards and things to hit to just increase the damage and breakage of every failed flight. Imagine if the wright brothers tested flying their first aircraft in their living room.

[@Maniacguy2777]

The tail rotor fan blade should be longer for airflow.
