Floating five blade rotor head for 450 Heli,It does not need V-bar.[1]

[@Firemandave911]

Im a new Heli pilot with my first 450 and before reading the comments just watching the video I was thinking WOW this thing is out of setup bad!

[@conexn]

You need to join a club that fly RC heli's and learn to setup it up correctly. 1. Tracking, tons of comments on this already. 2. Adjust servos so they are at 90 deg, 0 pitch. 3. Rotor speed, adjust rotor head speed, small heli's like around 1500-2500 rpm, 5 blade not sure on so check it out. 4. Adjust the sensitivity on the gyro, looks like it was a bit to high. 5. Check your CG, battery size & placement is key on a heli. Hovering is hard on batteries, cut down flight times, uses more power.

[@teamscreem]

Looks like you DO need a complex 3 axis gyro.

[@coriscotupi]

Main blades tracking is off. Gyro gain seems excessive. Flying area is too constrained.

[@gaetanboiv]

@ariechopper I've read the comment you did on these heads. I tried on a 3 blades head like that and with flexible blades , there were constant oscillation. My rpm was low. It is for scale, so no high speed. And I agree, there was a need of a big tracking work.

[@SH-ni8sh]

Looks good. Lots of lift probably. Your rotors blades look out of line though.

[@flyblood2045]

Lol you remind me when I was a newB :) Be careful rc helis are very dangerous starting from a 450 size and bigger you are playing with fire ! Take care and good luck

[@MrData14uk]

i like the fact you have a big letter H presumably to take off and land on but dont use it. Also it is a well known fact that the additinal blades have virtually zero benefits over a 2 blade system. my bird flew like this despite being rtf but some careful reprogramming over the next 3 flight has got my running sweet

[@markstevens5442]

Blade tracking is way out so is causing additional vibration, get that sorted first and then try flying the heli a little higher to get it out of it's own rotor wash and ground effect, things will be a lot smoother for you :)

[@markstevens5442]

Just noticed, the first set of blades you had on only work with the rigid rotor head which has no flapping movement in the blade grips, The flex in the blades takes care of that. You have the floating head fitted which has the flapping built into the head so you need to use rigid blades with that one (as you did with your second set of blades) Both heads will work without any V-bar etc so long as you have the right blades fitted ;)

[@rigididiot]

Actually, neither... I have flown all kinds of configurations of unstabilized multiblades in the 450 size, and they all work. They do all respond differently, but they are all flyable without FBL. This dude just cannot fly. Here's a vid of me and a friend, both flying different rotorheads, both flying without FBL electronics. After the 3:40 mark you can see for yourself that they are flyable, not limited to a bit of hoovering only. kzbin.info/www/bejne/qnvPp5eEpceMhJI

[@Intomars]

Yes, you definitely need to track those blades! Not sure how you would go about doing it though; maybe five different colored pieces of tape. :)

[@joshyarbro5002]

does not need vbar it needs help and a pilot

[@ariechopper]

Hi, I have the same rotorhead with the flexible blades, try to do some blade tracking bro.

[@markstevens5442]

The flexible blades only work properly with the rigid head. For the floating head you need rigid blades. I have a scale 450 size little bird which has the rigid 5 blade head fitted with the flexible blades, That works fine and I don't have any V-bar etc fitted :)

[@acer1827]

wow your pitch curves really need some attention.

[@larsrosing5033]

Maybe put an angle on the tailrotor 45dgr bend up to put the tailrotor closer to the mainrotor plane. 5 blades gives a relatively large antitorque thus giving the heli a tilted attitude. Best of luck

[@shockburn]

Forth, blade tracking is so far off i'm surprised this didn't shake apart or crash, you seem to be pretty good at piloting, would like to see you fly a nicely balanced heli! Remember in the building stage, it's all about balance and accuracy,

[@TheDirtBiter]

Even a Rampant Rabbit doesn't vibrate as much as that! You need to get your blade tracking right and your phasing on the head to benefit from the flapping hinge mechanism. I can see a blade gap of at least 1/2" after 5.50.

[@ribasferrari]

check the blade track, looks like they are on a multi track.

[@WWalter0227]

You should check your blade tracking, you can clearly see that that tracking needs work.also what's up with the Bobbiing up n down? I though might be that your pitch wasn't enough to lift it but then you took off the ground. What's goin on?

[@fatqwert200]

ya but think about ducted fans. same principle. i think what your thinking is actually having to do with pitch and airfoil shape. pitch more than 15 deg is said to cause drag and air separation (what your talking about) less than x? deg thers no lift ie aprx 0 pitch in this case. plus he has his throttle and pitch curves incorrect for this setup. i run 85% thr and 4deg pitch in normal mode, for hovering, on a 450 size. for (2 blade)

[@TheOnlyImp]

Been flying 3D for a while myself. I reccomend you to start using a pc simulator, and start gaming on a xbox tbh. Both those things help. I also know they have a drone type of game on xbox, that will help with muscle memory in your fingers. That being said. I strongly recommend starting to fly, whil i a open area.. like a football field ;)

[@DylanWintersteen]

Cool Build, I like the flexible blades. HOWEVER, When you are such a small scale having more than two blades can actually give you less lift. That's because each blade is following in the others turbulence, so you end up beating the air instead of slipping through it. Though for a 450 you might be ok. I don't really know the math on it.

[@mk6315]

But they look and sound so awesome 😁

[@OnceShy_TwiceBitten]

Damn flex in those blades.. can u say tail boom strike lmao

[@stealhty1]

Next available flying field is at the other side of the country

[@lowtus7]

Does not need V bar, but does need lessons on setting up a heli safely. Man this was painful to watch. I hope you have it sorted, but feel that heli may have gone to the big air-park in the sky by now.

[@hirox1955]

feathering shaf does not exist. The mechanism in which a rubber damper moves freely exists.

[@rondolch6608]

@ 5:30 you can really see how far off the blade tracking is. I'm sure it was a handful to fly. Hope you get it sorted out. Bet that thing, once set up, would do some great autos.

[@GodprefersDiesels]

The way the head wobbled around in the beginning, is that normal at startup? Mine does that too, and I always wondered.

[@elenastoenescu642]

what is the angle of phase lag? 90°or less??

[@Angry.General1461]

Why cant you just hold it still and let it hover????

[@es1co2bar3paul]

@ariechopper and learn to hover too and balance blade i am wating on a quad head to do some 3d

[@gaetanboiv]

By your poor comment, you gave the proof that you never flew anything but 2 blades. Tracking of more than 2 blades is easy and not very long, and if you don't crash, you probably will never have to do it again... But you are right when you wrote that in this video, everything is out, phasing, tracking, brobably balancing too.

[@shortclips7052]

Why is there blade flapping in rotor systems?

[@markstevens5442]

Firstly it allows a natural amount of dihedral for stability and it is also there to compensate for the effects of asymmetric lift caused by advancing / retreating blades ;)

[@jontykilpatrick]

Jesus. Never has a heli needed setting up so badly.

[@OnceShy_TwiceBitten]

And thumbs up if u were waiting to see it slide into one of those green stumps haha

[@steffanjansenvanvuuren5061]

Hi, were can I buy a rotor head like that? Good effort their! How is your flying these days? Expert by now... Hey?

[@aureliorodriguez5136]

CopterX.

[@TheMoffBoy]

are these also known as flapper blades?

[@MrBlurie23]

What kind of a feathering shaft does this use?

[@m313ana]

what size rotorblades did you use? and Tail rotor also? I had to use 250 main and 600 tail to keep mine from just spinning around.

[@TheFLNative]

lol how easy is it to autorotate on those things???

[@gangsta7380]

[@KevinHartman84]

Why does this video have 92k views?!? Why did youtube think I wanted to see it?? Yeah, those pesky 3-axis gyros are nonsense....look how well you can't even hover without one LOL! Not sure how you can comment on not needing a flybarless controller when you cannot even hover :facepalm.

[@hgvbdgbf]

You need 3 axis gyro

[@bladerunner469]

If you had the weighed blades it would fly much better

[@George241312]

Did you put a vibrator on it ?

[@christiangruhn7365]

You need better blade dampeners, last thing you need are those blade flopping about.

[@anlpereira]

Are these blades 315 or 325mm?

[@nightflyr1]

You may have better results by using rigid blades on a flapper head and flex blades on a rigid head

[@YieSing]

how do you track all of the blades?

[@markstevens5442]

They definitely have not been tracked in this video, hence a lot of the vibration.

[@chrismofer]

judging by the flight attempts it definitely needs a vbar or you need to become more skilled with regular flybarred helicopters before trying to fly this. it looks very unstable.

[@chrismofer]

also tracking being out a good half inch or more is not helping

[@SkeyeDreamer]

i bet your esc and motor were burning like hell...

[@sanchezgutierrez3484]

you can get them on ebay for arownd 50$

[@andytobias8609]

Great example of what happens when someone has an awesome machine but doesn't have a clue how to set it up or concern for safety before spooling up the main... The video should be titled, WATCH! As I slam this 5 blade heli into the ground a dozen times! FUN FUN HAPPY FUN TIME!

[@dezent]

"This design eliminate the need for complex 3 axis gyro system." Wow yes good idea, lets use 5 rotorblades instead!

[@helicopterovirtual-msfs6254]

Excelente.

[@gaetanboiv]

Never tried, but Bladerunner do it. Check on his channel.

[@MikeDawson1]

blade tracking is way off, looks like a nightmare to set with 5 blades and flexible grips!!

[@JamieKugelmann]

lol why are you flying on top of a roof? real big danger hazard if that thing goes down

[@Sereniitty]

LOL this heli is like .. : KILL ME PLEAS

[@shockburn]

wow.. a couple things here.. first of all fix your gear mesh and drive train, sounds way too tight mesh and warped. Second, find a field don't test something like this right next to a steel fence (unless you like spending money) Third, your blade phasing looks about 45* off for proper aileron and elevator input.

[@AnonymousEngineer1919]

critisize... critisize... critisize... this is how i feel

[@SOLDOZER]

Holy mother of God. Everything is setup wrong on this.

[@TheDillonma]

is flies like crap

[@NiCadHeliPilot]

My God, that thing is UNstable =O.O=

[@barringtonmcfarlane4739]

oi mate realflight

[@Kerionite]

Rigid rotors are better

[@lapua338f]

hobby king

[@ManJunk427]

you would think you would learn to fly...before going to an advanced head like that.... not to mention the unbalance omg

[@michaelduernecker684]

OMG what you do with the Heli?? Very Bad Setup of all. Why you dont go to a Profi? And yes, we could fly all Heli without V- Bar and without Bell Hiller Head. Of Course.

[@MrBendoudou]

le gyro , le gyro , le gyro , mal régler !!!

[@paulpongos3056]

does not look right at all tracking,balance

[@paulpongos3056]

destroy that thing while your at it

[@gwaggglitschumpel]

dear guy - first of all setup problems - your gyro is set MUCH too aggressive - try to learn handle a classic 2 blade fly bar helo before hurting your nice machine..

[@gruuthuse]

Pff your blades are everywhere...... hard time enough tracking 2 blades let alone 5 . You can clearly see at (time 5,25) that the blades are off........

[@3000gtwelder]

WTF is this guy doing?

[@tennguoidung137]

kaka

[@OnceShy_TwiceBitten]

Omg if thats a sales vid. Fail. Not even flyable. Alignment way off. Wobble out the ass. Atracking jacked up.

[@Imperadorio]

It's looks like you should learn how to fly basic first. Keep trying !

[@isidoro-x1h]

No vbar no party
