[@TotallyNotNuclear]

You are a true gift to the FPV community. Thank you so much for all of your work! Looks like an amazing frame! I can see you are truly exited about it. Love your work man.

[@IDriveAnAudi]

I built one last weekend and I'll tell you it's an incredible frame. It's almost unbelievable how stiff it is and that there is absolutely no vibration or jello in the video. The black box analysis shows an even better result (if that's possible) than where Chris shows the frequency plot on the debug graph. Mine is absolutely black, not even showing motor resonance traces. Just unbelievable and its performance regarding propwash or the lack thereof is equally stellar. Last night I bought a larger 3,000mah 6S Lipo to try some mid-range flying. So far I've just flown it on a 1350mah Lipo for about 5 minutes at a time. What an achievement!

[@dutchfpv7010]

Not just arms, control arms! What a sick design brother. Yeah the rulebook never went away. If you're making a flying machine Ultralight should always be a prime directive. That concept is older than drones. I released a 5" Ultralight racer, the ULX, with SpeedSourceFPV last year. It builds to half the weight and cost of traditional racers, with no performance disadvantage whatsoever and unprecedented stiffness and durability (lemme know if you'd like to test one). Many of the principles you've employed here are things I've been stumping on for some time now. But your elegant design and eloquent explanation are definitely going to make more believers than I have. Its so well done. I never expected anything less. Kudos and please keep amazing us with your science and innovation.

[@modquad18]

[@gadgetrc94]

My AOS7 is by far my favorite frame. I designed it for high speed chase with a GoPro and it performs superbly. I'll bet a fresh UL would be even better, but I'm concerned about how the arm tabs wear over time. Has anybody tested the UL after a couple rounds of assembly/disassembly and a bunch of flight time? Thanks for what you do!

[@terpsquirter7107]

I got a colored carbon ul7 🎉🎉 can’t wait!!

[@noahpalladino]

A great design. I designed a 6" box racer with similar hollowed vert arm and out box features a few years ago. However My reasoning was that since material could be removed in the center of the out box vertical sections, that the depth of the fins could be increased for more authority. The trick is to use sheet material such as vinyl or a better adhered film to close the surface back up for less turbulent flow.

[@jeffparisse4202]

I fly in the desert so when I crash, it’s on rocks. The AOS7 frame is indestructible (two crashes, only broken props). I really like this new design and may give it a try.

[@ChrisRosser]

The UL7 is not going to be as durable as the AOS 7. The thin arms are lighter but not as tough. That's in line with the AOS UL frame philosophy. 👍

[@jakub9916]

Are you planning to do a test of motors for 7" quads? It will be great.

[@alpinegoat]

I’m interested to see the new soft mount for the 03. I had an issue with shaky video from the 03 on my AOS 5 but it went away when I glued the lens barrel. DJI Support was trying to blame vibration from the frame. I sent them my black box logs but they said they can’t look at 3rd party data.

[@Paulwhittingham]

Ok I'm sold. And this will be my first ever build too. In for a penny... Maybe wait for the 03 adaptations however so I guess I'll slap the rest of the shopping list together in the meantime

[@ChrisRosser]

Depends on your needs. If you need O3 ND filters and EIS then maybe worth waiting. If you plan to run a GoPro then the current version already supports all the features of O3 you will ever use.

[@VincentFPV]

I made similar construction years ago and i think it is only fully printable frame (Ladder 7 on thingiverse) that is stiff and durable enough. But you made it better with the cnc milled carbon parts. :) I changed the process to forged carbon onepiece frame (The Fragile One on Thingiverse ), which is not good for mass production but cheap and perfect for low volume production just for me. :D

[@JPspinFPV]

Straight away, triangulated truss beam structure makes perfect sense.

[@kandredfpv]

Love the new concept frame design. This aspect of FPV has been starving for innovation with most frames just being a carbon copy of each other with small variations. It is worth mentioning than the vertical arm design has been done before with the Karearea Talon but the cutouts and double struts are quite novel. Well done Chris. 😍

[@ChrisRosser]

The talon was an injection moulded frame right? Vertical arms have certainly been done before but I think this is the first mass manufactured design for 7" frames.

[@sorcererspicnic7052]

This looks great! Any idea when the frames will be back in stock?

[@christhorney]

i just ordered the aos3.5 to replace my crux35 frame, mainly i wanted the replacable individual arms and im hoping being 4mm instead of 3mm it will be a bit stronger, and far easier to replace when i do break an arm. plus im hoping to benifit from the quieter frame as i was having a lot of issues trying to get a smooth tune out of the crux35 frame without getting hot motors. im just wondering if i can use dry lube like graphite powder on the joints instead of dampening grease as you suggest as the graphite will remain much much cleaner.. hopefully later this year i will be able to afford to build a 5 and a 7 inch and ill 100% be using this frame for my 7 inch and the coloured carbon from cncdrones is sweet i cant wait to build my clown quad with all different colour arms and plates as i brought all different colour spares for my aos3.5 LOL!

[@BooDevil65]

Interesting design - I could see the vertical arms adding drag in forward flight - would love to see an A/B comparison with a similar 7" with traditional arms to see if that's offset by the reduced cross-section in the propeller wash

[@ChrisRosser]

When we think about arm aerodynamics we have to remember that the prop has a huge impact on airflow direction. When the quad is flying forwards the air is not hitting the arm from the front. The air is being pushed down onto the arm by the prop. The prop thrust column has a much bigger impact on airflow direction over the arm than any movemement of the quad in steady flight.

[@prki1024]

Nice to see something new in 7" space. I guess this would also scale well to 10" and beat the new Rekon 10 in pretty much every category: weight, stiffness, durability.

[@GregQuillen]

Rekon7 frame is lighter so rekon 10 prob lighter. But UL7 is way way stiffer. I'd imagine flies so much more smoother.

[@prki1024]

@@GregQuillen You are right. I just found UL7 weight listed on cncdrones at 175 grams. Reckon 7 is listed as 152.7g in some sources. So it is a little heavier but the diff is not that big when you take AUW into account.

[@GregQuillen]

@prki not much of a difference. The big differences come in the form of stiffness and battery space over the rekon 7.

[@highwaymen1237]

Chris, I plan on building a maximum duration observation platform. Your arm design should help facilitate that result. What do you estimate the maximum duration flight time would be with optimal motors, propellers and battery? What motor propellers and Battery would you use as the first estimate. Thank you.

Very particular and interesting building structure ! I have an AOS 7 classic first version, is UL7 wider? I mean are motors on the sides ( 1&2 vs 3&4 ) far then in AOS7 , or the distance is the same ?

[@ChrisRosser]

Yes the motor spacing is wider to support 7.5" props and go pro.

[@wearemany73]

Super smart design.👍 I wonder if they'd be any difference in flight characteristics if the arms didn't have cut outs, owing to them behaving like a defacto lifting surface due to an approximate 45degree angle of attack..🤔

[@erick4188]

Possibly, but I'd say it might only be efficient or beneficial at more than 45.. probably closer to 70 or 80. I have wanted to see a quad designed with this in mind, seems interesting

[@ChrisRosser]

Aerodynamically active surfaces are an absolute no no for camera drones as they make the drone more susceptible to turbulence which leads to shaky footage. If you've flown a fixed wing FPV you'll know what I mean! 😁

[@JekleFPV]

I have some questions about the (LR) performance of this frame. First it’s almost 20 grams heavier than the frame I currently use for LR. The second reason I question the efficiency is it’s aerodynamic cross section for forward flight, as it appears to be significantly larger than my current frame. The different arm configuration probably makes no difference, given than most of the arms are under the airflow of the props anyway. But the larger cross section of the body is going to make a significant difference in forward flight. However much I appreciate your work regarding frame resonance, I doubt that that would weigh up (literally and figuratively, pun intended) to the performance drawback of increased weight and aerodynamic drag of the body in forward flight. So I guess my question is if you’ve done any real analysis of the aerodynamics and/or cross section in forward flight?

[@willpowerfpv3246]

I actually JUST ordered 2 of your frames a few days ago. The Cine25(been looking for a decent 2.5" to replace my 95x, for at least 6 months) and I just had to try your new 5" too(will be swapping out of my beat up Moongoat). This is the first 7" that has excited me since I built Bob's 7" CineGlide with his 30mm motors, which is the best flying 7"(I've flown) to date. That thing flys amazing...TONS of power too. I also have very high hopes for this one, possibly being what I was always looking for in a long range 7" INAV platform...and I've built 8 of them so far. Half of them having some strange flight dynamics issue. Awesome design man!

@chris Rosser New frame looks great, Im enjoying my 3.5 O3 at the moment. I have a question regarding the 3.5 though…the camera plates are very loose fit when properly tightened and assembled…it is causing a horrible jello/wobble in the video feed to the goggles (osd elements stay solid) Is it possible I got a bad cut on my frame? Do any other examples of your frames have this play (easily a mm or so back and forth) in the camera plates? Im hesitant to use glue due to the inconvenience and not really in the mood to design a tpu part to hug the plates and secure them to the frame. Look forward to hearing back.

[@ChrisRosser]

Hi, sorry to hear you've had this issue. If you think it's a manufacturing defect the best thing to do is to reach out to your manufacturer and they should take care of this for you. With the standoffs and camera in place you shouldn't have any movemement in the camera cage. If you are using an O3 camera you may also want to check for a loose lens assembly.

Not a replacement, the AOS 7 is more durable but heavier. This is higher performance and lighter but less durable. Depends what you need.

[@DigitalArtisan77]

Should put a damper/strut brace between the struts and it will remove high frequency motor vibration feeding to FC and protect against crash even more, the little locator tabs at the motor mounts being a large weakness in a crash as are of a small area,suffer forces in shear and of a torsional nature.

Please improve the rigidity of the 5v2and 5.5 v2 They break arms and x plates constantly This is a recurring problem. Also not enough thread engaged in the arm to stand-off bolts.

[@chrisbee5481]

Yeah I have the same weak arm issue on my aos 5.5 V2. The carbon arms also slowly start delaminating. Give them a Twist once in a while and see if that is the issue. There is a loss in stiffness. The new aos 5 O3 frame apparently has thicker arms now. They are compatible. Four arms are unfortunatly over half the price of a new frame. They really should have given 2mm longer screws for the arm mount of the frame. I ordered some longer ones. They didnt hold well and I also striped my standoff threads they screw into. My Apex frames are very solid and never have any of these issues.

[@ChrisRosser]

Hi Chris, thanks for the feedback. I can confirm that I was made aware of both these concerns some time ago and they have both been addressed in the latest versions of both frames with slightly thicker arms and longer screws.

I bought the AOS7 Evo frame and I’m struggling to have it perfectly flat. It’s a bit twisted when placed on a flat surface. I made sure all fit nicely, then tightened the screw to the maximum, but still, it don’t lay perfectly flat. You, Chris Rosser, are one sweet-talking scammer 😄

[@ChrisRosser]

Sorry to hear you're concerned about this issue. Although I'm not directly involved in the manufacturing of the frames I can share my experience: carbon fiber plate (especially thinner pieces) with high fiber content (which is the high quality plate) is rarely if ever perfectly flat. Even with a balanced layup you get some slight pre-stress which causes a saddle shape. This doesn't affect flight performance, but I can understand why you might be concerned about a quality issue. If you're having issues in flight please let me know by email and/or reach out to the manufacturer.

I've been thinking. The weakest part could be the motor mounts specifically the top plate not having enough material & I'm having seconds thoughts about flying this thing & definitely don't want to use big motors. I admit i have not tested the durability of this frame, but i just think we should have a lift, Brittleness, & durability test to be safe. Wasn't there an only other reason why drone arms had to have thick motor mounts? Don't get me wrong, I own 95% AOS 7 frames, because they're the best, but i just think people would feel more comfortable with beefier motor mounts. Would be awesome to see a big motor thrust test 2808s 3008s or something. Well cheerios🤓 Update▪︎▪︎▪︎ Insanely good frame & definitely buying more. 🤯🤯 So I said fck it & flew it anyway & holy sht if you already have the AOS 7 frame you should really try this one. It turns your gopro into a professional looking Camera. No joke, I can see details of structures, mountains, landscapes from miles away. As far as durability, I feel safer with more material on the motor mounts. So, I've ordered 4 more top motor mount plates. If you were me would you adhere the plates with epoxy, dampening liquid, or just dry?

[@brokenbonesmedia26]

What about electrical noises transferring to the hardmounted connectors? Whenever I had SMA connectors mounted directly on carbon (I only tried it with analog this way, so don't know how digital behaves then), I had TERRIBLE video noise as soon as I armed the quad, making it basically impossible to fly. Do you have any solution to that? Or was I just unlucky/had a setup with a bit more noise?

There is *a lot* of flexibility in battery weight. For LiPos the frame flies great with 2x1100mAh 6S packs (400g) all the way up a 6000mAh 6S (900g). For super long range you'll want to go with 6S Li-ion packs. Either 3x 3000mAh 18650 based (900g) or 2x4000mAh 21700 based (900g). I would probably go with 3x3000mAh 6S Li-ion packs but make sure you have a throttle limit to prevent drawing more than 10C discharge from the Li-ion cells (that's still 90A for 3x3000mAh though!)
