Official RotorScale AH-6 Attack 450 Size Helicopter Discussion Thread

[Baseline]

Can anyone send me a diagram of connections for a Bavarian Demon 3x and a Futaba 3008 in the Little Bird - also ID the servo wires by color code - lack of instruction detail holding me back,\.

I'm just curious, did you find the information you were looking for as I have a 3x in mine as well.

Hi all, just joined the forum because of this thread. I got my ah6 last week, but looks like it will take forever to get her flying. The esc (hobbywing platinum v4)needs programmed, and it takes another peice of electronics to program it, and i havent even ordered that yet. I bought the flywing fbl or gyro or dfc, im thinking its just 3 words for the same thing, but it needs programming too. I'm using the radiomaster 16c, it needs programmed as well. Pitch gauge shows the blades differ by 1 degree. Half a twist on the linkange gives 1/2° movement, so now therye as close as i know how to get them. Still waiting on blade balancer. Before i found the ah6, i found stl files for the fueslage and landing gear at cults3d.com,
https://cults3d.com/en/3d-model/game...s-rc-helis-450
for $50.00 and bought them. I resized them to a 250 size using maxon c4d, sent them out and was told the slicer found more than 50 holes between the few parts i sent off to print. If there are any 3dp artists out there, ill share the files in exchange for them to be made unholy.
just a fyi, my ah6 came with a tarot 450 sport v3, with 14t pinion, and 150t antirotation gear and a 1800kv gartt brushless. Early in the thread its mentioned its set up to run 6s battery....my caculations on that head speed equals ...22.2v x 1800kv =39960rpm
divided by 150 multiplied by 14 gives a head speed of 3729.6 rpm. Seems kinda high to me.

Thanks, now get get some printing done.

[Astronome]

I must be blind as a bat, I keep looking for the STL files and can not find them I saw the post that said it had a zip file in it. Just got a printer and want to print out the parts, thanks

Hello,

The Zip folder contains 27 stl files, I just downloaded it.

Delete I found it!

Agree 100% with ridgerunnr. Get a pod and boom and not only learn the basics of flying first but also setup and repair. No scale helicopter will fly right out of box. And the smallest of things can make a good helicopter fly like crap. With new flight controllers a bad setup will be masked by over correcting FC’s which lead you down a trail of trying to make a bunch of wrong fixes.

Good day gents, I am new to helies and thinking about picking up AH-6. ...

This is most certainly NOT a good first heli!

Firstly, flying a collective pitch (CP) heli is very difficult and takes a LOT of practice before one reaches the stage where crashing becomes rare. I would strongly recommend getting a robust (crashable) micro heli such as the XK K110 or K123 and learn to fly on that - (note that the K123 is a scale AS-350 and is my favorite micro). Also, even before flying the micros, get a flight simulator and learn to fly on that first. If you can't hover in the simulator, you won't be able to hover in real life.

Secondly: A scale heli is much more difficult to work on and repair and is much more prone to damage in a crash. One should first become familiar with setting up and working on a simple pod and boom heli where all the parts are easy to access. On a scale heli, if you crash, you must remove the mechanics from the fuselage and this is a non-trivial task.

I have been flying helis for nearly ten years now and currently own all six variations of the Rotorscale 450 helis and they each require a teardown and rebuild before they are flight ready. These are NOT plug and play and NOT for beginners.

Once again, get a flight simulator (such as RealFlight or AccuRC) and learn to fly on that. Get a good micro such as the K110 or K123 (and get a 2nd complete spare heli) and use that to learn to fly in real life. Once you have mastered simple hovering in all orientations and can maintain control at all times, then you will be safely ready to move up to a larger heli.

But before you do any of that, I strongly recommend going to the following website by John Salt - he has a LOT of experience and great advice for the newbie heli pilot.

grabbed one for myself as well as soon as the "in stock" email was received.

[fleetsailor1981]

After my first post in June 2019 I am happy to say I finally got my little bird in today, I am looking forward to working on this. Heck it only took me 2 years to get it. Now the fun starts.

Thanks for getting back to me Alpha.

What about batteries i need for this?
Is it 4s or 6s?
What size battery should i be looking at?

Sam CB Hi Sam, the RotorScale lineup has evolved since its initial release. Suffice to say, the website is always the most up to date resource for a model's price, specs, equipment, and recommended/required components.

After a long Covid-induced delay, we began restocking the RotorScale products last week, including many spare parts. If you have any hesitation, feel free to refresh the page until those spares are put back In Stock online. More than half of the AH-6's spare parts are currently in stock as I write this, with more being restocked. Please note though, these RotorScales tend to sell out quickly whenever we restock them, so as I mentioned, use the website as an up-to-the-minute guide whenever you're actually reading this.

As to your second question regarding value, I suppose it's rather subjective. There aren't any other 450 sized Scale fiberglass helicopter PNPs out on the market that only require your flight controller to get in the air, so personally I'm willing to pay a bit more for that aspect. Not to mention, I'd say our spare parts offerings are fairly comprehensive. I like tinkering with the scale bodies to make them more scale, which is something I can't do on the 3D/Sport helos I own. All of those aspects combine to something that jives for my personal target value proposition.

On the other hand, if any pilot is on the fence about what it would take to get a RotorScale 450 PNP in the air and operating to their liking, I would understand if they had pause. In fact, I wouldn't recommend these or any scale fiberglass helicopter as a first helicopter or first flight controller install project. It's not that they're difficult, per se, but more that they're very exacting. The road of "safe" is narrower.

Good day gents, I am new to helies and thinking about picking up AH-6. I also have some questions regarding the model and availability of spare parts. Hopefully i can find my answers here.
At the beginning of this tread Aros posted specs indicating this heli is 6S but on Motion RC site, product description it states 4S... so, which is it and which batteries work good with it?
I am a bit concerned that spare parts are "out of stock"... Is this something temp or is there an issue getting parts from manufacturer?
Also others reporting missing parts and servos.. was this addressed?
Overall, i have looked at this heli and other helicopters in 450 size by RotorScale and to be honest i am not getting too many positive vibes. If i were to estimate the total cost, i think i have this somewhere in $600 to $700 range. This is to buy everything i need plus batteries to get it up in the air. The price tag is a bit steep so, i want to make sure i will not end up with a problem on my hands.

Most appreciate your input!

Does anyone have the 3dpup file for this 450 little bird?

Files were posted earlier in the thread: https://www.hobbysquawk.com/forum/rc...301#post218301

keep waiting for that email notification Little Bird is back in stock........comeon Alpha..

[SilentTiger]

Unfortunate you had so many issues. I’ve been wondering about the stock servos myself. Not a whole lot of info on them. If anyone could chime in what MHz are you using to sent signals from the flybarless system to the servos?

[echopoint]

I ordered one of these just after Christmas. Finally got around to removing the mechanics from the fuselage and set everything up with an IKON. On spool up, I was getting some horrible vibrations. and the whole helicopter was moving left with no input. I have several other align 450s that did not have this problem. From the top, it looked like a bent main shaft. The button head is vibrating about half a centimeter. I took the head assembly and checked the shaft. It looks straight. I replaced the swash and head with a different one and still get the vibration- but not as strong. I am now going to replace the shaft, gears, swash and complete head assembly. The issue is that these copters use a longer shaft than a standard trex, so I need to redo all of the links. In the process, I discovered that the rear swash servo was very loose. I'm hoping that this is what is causing the vibration. I can't believe that this was ever tested in the factory.

There are a lot of screws that are loose and nothing appears to have thread lock. Word of advice to everyone to go through everything very carefully before trying to fly. These are not assembled very carefully (or at least mine was not).

[F106DeltaDart]

Thanks for the quick reply alpha. The four blade would be a nice touch and a little closer to the scale look. But in the air really Dosnt matter. 😎 If it’s ever available I will jump on it fast. Until then that Huey just may need to be added to my 450 collection.

If you are looking for a 4 blade head, Hirobo has one in stock: http://www.ehirobo.com/rc-helicopter...-450-heli.html. Planning on running one of these on my 450 A109.
