A 200MPH drone you can try TODAY. AOS Project Update!

[@ChrisRosser]

Day 1 update! You can buy the whole kit in black from CNC drones for $124. If you want to buy coloured prints from brain3d youll want to buy just the CF and hardware from cncdrones. The pricing is not correct for that at the moment (should be $64) but will be fixed soon!

[@nelsondcp]

Would it not be possible to buy the CF and hardware parts from cncdrones and get access to the 3d print files? It would be great to be able to experiment with different colours and filaments.

[@rapamune]

I asked this further below, but could you include anti-vibration grease and locktite for the build guide video, so we know exactly how to do this accurately (and optimally)?

[@XwingFPV-b5v]

I'm definitely excited about releasing a fast forward kit as well... you really need a one axis camera gimbal to see where you're landing. I'm curious to see if you will refine this beyond just a sprinter.

Super Cool 😎 I think I found my next project. Thank you Chris and kudos to Brain3D and CNC Drones. 👍

[@KK-ol5ov]

Exciting times, I cannot fly well at all but been wanting a speedy drone like this for my collection. My favourite drone of all time is AOS 5.5. I did not like the AOS 5UL so much but maybe I didn’t build it so well. Keen on the 7inch frame as well.

[@sketchpv3080]

Wow, a high-speed drone kit for the masses?! Super neat. Bet that thing takes a little while to master vs a normal drone, mostly because of the camera angle. Gonna be landing somewhat “blind”.

[@ChrisRosser]

Very easy with someone standing beside to guide you down for landing!

[@MessFPV]

Not necessarily, I have a similar quad for years now with a 90° tilt camera (I don't understand why using less except if it is for subject filming), and to fly it easily you just have to swap roll and yaw channels, you fly it then like a plane, and for landing I just use a switch to put back channels in the normal configuration and activate stabilised mode for los landing or rth for auto-land.

[@brandon9689]

A strong foundation of acro mode line of sight is probably very helpful for landing something like this gently.

[@Vousie]

@@MessFPV So, in summary, you *will* be landing "blind" in FPV, so don't try it. Land LOS or with RTH... Still not great. It still means that it's important to have that warning for people that they won't be able to land "normally" (i.e. in acro mode with FPV).

@@ChrisRosser A "fast camera drone" that can't take an HD Camera, so you're forced to rely on your FPV camera being good enough...?

[@ssevetFPV]

Amazing work Chriss!, I have a few questions: On your video the motors are EMAX 2808 pro 1900kv(?), Do you recommend the velox like "hinted" in the picture? :) The current recommended prop is HQProp 5.3x8 thin prop. In the past (way back 2014.... LOL) i tried thin props and under high speed they bent from the load, making a new scream sound Isn't this an issue? (planning the 8S route, maybe with throttle limit at first) Should I put on the build an XT90 or stronger ? we can reach 220A draw (i'm amazed how XT60 lasts ) Lets say I do the whole battery in one pass with the XT60, will it hold? We once had a drag race on 4S and the winner (i was 2nd LOL) had his XT60 from quad fused to his battery. Will AM32 be okay for this build? You mentioned something about rampup time that BLheli32 accelerate faster, but I really dont want to buy deadend ESCs... (horrible what these guys did to the hobby, but it will be better after a period)

[@mikeselectricstuff]

How would they know if you exceeded any regulated speeds?

[@ChrisRosser]

I'm not sure what the regulations are in your country, In the USA think it's needed for commercial flying that you get a part 107 waiver for high speed operations.

[@conorstewart2214]

The same way they know if you break any other law. People seeing you and reporting you or you post videos of it on the internet.

[@markwilliams5654]

Most countries have an energy limit not a speed limit or a weight limit it's actually energy on impact

[@Vousie]

@@markwilliams5654 Pretty sure the US has a 100 MPH speed limit for all drones... But other than that you're probably right - AFAIK most countries base their limits on weight and don't care about max speed.

[@wakingdreamfpv]

Wow looks epic! Any sweet chase footage out from this quad?

[@bigredsfpv]

Will it be possible to upgrade the camera cage if you are using a previous version of the AOS 7 frame? Just wondering if that would be possible as the front looks slightly different now.

[@ChrisRosser]

Yes, a new top plate, bottom plate and camera cage is required. If you have the EVO I wouldn't worry about upgrading unless you need one of the new features. Just enjoy your AOS!

[@skky_fpv]

Amazing high speed design 🤩

[@mikybaga9762]

the motors are 6S rated so why can you use it on 8S, because it is not the voltage but the power that matters? so I could use any motor e.g. at double the voltage and half the current? thanks

[@mikeselectricstuff]

I'm no aerodynamicist but I wonder if it would it improve drag by raking the arms backwards instead of having them at 90 degrees.

[@ChrisRosser]

Not at these speeds unfortunately, backward sweep really helps when you get into the transonic regime above 0.6M or so. At lower speeds backward sweep increases wing surface area and therefore drag.

@ChrisRosser Hi Chris. The AOS 7v5.... Will Avenger 2812 1115kv motors work with that frame?. I know its a little bit big motors.

[@ChrisRosser]

A little big and a little low KV (for 6s). 2807 1400KV is the sweet spot with a 5000mAh 6S

[@Wontonsoupz]

@@ChrisRosser Thank you Chris. The reason I asked about the 2812 motors is because I already have them build on my FR8 with 8" props, but I'm not a big fan of that frame. So that why I wanted to see if I can gut it and move the components over to the ASO7V5 frame.

[@gokartmozart9430]

Do you think the texture of the 3D print will have any effect at the speeds it can fly? Would making the surface smooth help or maybe the texture helps like dimples on a golf ball 🤷

[@ChrisRosser]

Smoother is better for high speed at these Reynolds numbers.

[@BLACKON.]

Great job, congratulations, I respect you and I consider you really good. I ask you, have you ever tried to laminate the carbon of the frame in such a way that the direction of the fiber is never directed from the motors to the fc?

[@JinKee]

we need to paint a Mario world "Bullet Bill" face on it.

[@rapamune]

My first drone build will be a 3.5 or 4 inch. Any version 5 kits inbound (incl. motors) for such a build? Did you ever produce a build guide with the anti-vibration using viscous grease? That would be very helpful to difference where to use locktite and where to use grease :)

[@Vousie]

I think there's been various tests about the grease and it doesn't always work. Better is to just have a low-vibration frame, which most frames on the market already are. I recently built a 5" quad and it's just the standard build and it has super low vibration.

[@rapamune]

@@Vousie CR already proved highly viscous grease helps in one of his shorts.

[@ChrisRosser]

Not yet, but I'm working on global supply with iFlight

[@kerrymillar4981]

Expect you camera and vtx to be smashed first time you hit anything and with the camera mount so high up it changes the way it handles, and thats way racers can fly so much better because of where the camera is mounted so its projection is centred to the centre of the quad making it so much better to fly but its way better than that green African quad with the camera so far forward i dont think i could even do a forward roll without looking like a beginner!.

[@Tomcat2_kanal]

Can one Tatu 6s 1800mAh battery power such a beast? In the RedBull drone, they were using 2 batteries if I remember correctly, so I'm not sure how long this can fly on the top speed until battery sags...

[@JohnIn2SonAZ]

Hey Chris, I would like to carry these at AddictiveRC! I am also an iFlight and Brain 3D Dealer as well.

[@ChrisRosser]

[@0b3rz0nK]

AHHHH COME ON. I just finished designing my own high speed design, weird old frame and custom canopy, but burned out motors because of wrong tune, had no time to fly it with higher kv motors before my holiday because I missed putting a whole to bind the Air unit (!) and the breakdown is more complicated. i see that you do not put as much emphasis on putting the center of mass forward as Maximo Bell. Looking forward to see if you get thermal issues while waiting for satallites ;)

[@ChrisRosser]

If you have no tail the center of mass must be forward. For ease of build, layout and takeoff a tail makes everything so much easier.

[@0b3rz0nK]

Never even seen your reply! As a seasoned KSP-Player I know about the importance of center of mass vs area. I don‘t know if the tails in all that dirty air will produce enough „correcting“ torque before the FC corrects, even with the sliders and filters being as docile as I had to make them to not burn up way to high kv motors. I am going to test that theory soon, my design flies with minor difficulties (RX loss after some promising passes) Did you ever try pusher vs. puller?

[@0b3rz0nK]

@@ChrisRosser Well, you were right. My design started "fishtailing" at about 270kph when I fitted aerodynamic shrouds to the arms. And without them I struggled and burned out a motor (yes, one?) at 260

Whats the weight?

Not sure why you'd wanna deal with analog anymore... Especially since it won't give you video you can really use. Better idea is the HDZero Race VTXs or maybe even the Walksnail Whoop VTX. Much better quality image, and still a very low weight for a sub 250g.

[@rares6216]

​@@Vousie Yes , but for high speed the weight matters , for a 400mw anlog vtx and camera you will have 3g , for me the analog quality is usable, I also fly walksnail, but the vtx takes more space and just sags the battery more on whoops , if I'm trying to build something efficient I will go with analog , if I'm trying to build something where weight it's a problem, I will go with walksnail

[@Vousie]

@@rares6216 That's only fine if you're flying fast just for fun or something. But a lot of people want to film things. In which case you need at least something like Walksnail where you can actually kinda use the FPV feed.

@@Vousie but runcam thumb pro exists and is wayyy better than ws
