[@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

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.

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

[@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

[@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.

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.)

[@kensmith8832]

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.

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.

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.

[@prawnmikus]

Wonder if mounting the motor horizontally and using a bevel gear would have changed the gyroscopic forces enough to give it more stability?

[@prawnmikus]

With the rotor, motor and gears all spinning on the same axis the gyroscopic forces were pretty huge. If the motor is mounted horizontally, then there would be gyroscopic forces on 3 axis. There also wouldn't be such a huge lever-arm hanging under the rotor, so the controls would be more responsive. Or maybe I'm missing something simple.

[@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.

[@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).

[@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.

[@tonymunn]

[@ehjones]

I'm completely ignorant, but my instinct would be to try to get the dremel COG under the rotor axis using non-parallel pinion/gear axes.

A belt and pulleys would be much lighter and more efficient at transmitting power than plastic gears

[@hamhouke]

I don’t know about lighter, because you add the belt. But it is a LOT more forgiving of slippage and sudden increases or decreases of motor RPM. I think they are inducing a whole lot of shock and vibration because the gear teeth will momentarily disengage when it flexes. A belt would soak up some of that difference in interface angle between the large and small pulleys. Also, when you take off, you really have to surge it to get it airborne. That is when the flex is worse and the gear slippage is the most detrimental.

[@wowonice1]

@@hamhouke I think a belt would allow both pulleys to be a smaller diameter than gears for the same reduction, reducing width therefore weight, creating space between them allowing use of a smaller belt and reducing the weight of the support structure around it

[@hamhouke]

@@wowonice1 Maybe, but that drive gear is pretty small already. If he made it smaller, that 22K RPM motor might burn though it due to the reduced surface area in contact with the belt. Of course, they could make the belt wider, but you would gain the weight right back. There might be enough torque with that motor to reduce the blade pulley diameter and get a bit more RPM to the rotors without bogging it down. Under load, the RPM of that motor is likely to be a lot less than 22K. I think that’s it rating if free spinning the spindle.

[@wowonice1]

@@hamhouke Agreed. the only way to know for sure would be to try it, though either way with less energy being lost to friction and noise, weight reduction might not be as important anymore as more energy reaches the blades
