I have the Siren F5 Split and two F3 Splits , absolutely love Quadmula!

[@PaulCrisafulli-if8yw]

I’ve beat on 2 F5 splits since they hit the scene and have had ZERO issues with the stack screws. If anything I believe it adds to the tunability of the quad. Quadmula stole my heart and I’ve not flown anything else since the maiden flight.

[@MysteryD]

Their PR team and CS are top notch also.

[@hazzahfpv6675]

Nice frame and I love the GoPro Mount solution! Also nice packaging, but man so much plastic waste. For me: just wrap that stuff in a paper bag and send it out. Those parts are not fragile.

[@MysteryD]

You could make a small gravity bong with the plastic tube. Or something.

[@AdamKouse]

Right?! I’m 100% on board with this. If the frame is good, I couldn’t care less about the packaging.

[@KaminKevCrew]

Regarding the press nuts - if anyone else out there is a bit of a tool-head, the Knipex Pliers Wrench is great for installing them. The jaws are flat, so they won’t put a bunch of dents in the press nuts, and the jaws move in a straight line and stay parallel throughout their entire range of motion, so it makes it easy to press the press nuts into the carbon while being correctly aligned the whole time. Oh, and the flat jaws won’t mar your carbon either (as long as you don’t go crazy pressing the press nuts in.)

[@falconfpv9467]

This frame flies so locked in. I’ve broken a couple arms on mine when slamming into concrete or steel but never bent a stack screw. Actually think it’s a great idea with the silicone tubing.

[@jackinabackpack7599]

If you're making a series out if this, then I would LOVE for you to do one on the newest TBS Source One v5! I know it's basic, but it's cheap and available absolutely everywhere in almost every store.

[@Nathan_Adams]

Having had a whole bunch of experience with the V5, I love the frame, it does not fit an 03 air unit, and if you're learning Matty flips, you will likely crack the rear end of the frame in a lot of places. I'm on my third rear mid/bottom plate

[@cheechfpv]

Exactly! Also the glide is another great affordable frame that’s very durable.

[@mavfpv]

@@Nathan_Adams yeah it does! v5 03 build here

[@Nathan_Adams]

@@mavfpv since the camera plates are only 19mm wide (o3 is a generous 20mm), I assume you are using a 3d print to hang the camera out front or replacing the camera plates with a 3d print? I have seen some built with an o3, but it always seems like big compromises in terms of durability/protection of the camera. If you want a source one, the v3 can accommodate the O3.

[@mavfpv]

@@Nathan_Adams true, 3d printed mount replaced the front 2 standoffs. I've gotten some good LR flights with it, just posted a PNW vid i did all with the source one v5 and 03, but for peace of mind id go with a different frame next time.

8:20 they have 20x20 mounting on the mini version of this frame (It's still 5 inch, the normal one can actually do 5.5 inch.) It weighs 91.3g !!!

[@squintsfpv]

Came here to mention this. I've also seen that more stack screws get bent on the 30x30 version compared to the 20x20.

[@SteeveFPVeee]

[@GarethDix]

I’m building a sub250 3inch version of this as my first build… and it’s pretty easy. The O3 air unit is soft mounted with TPU inserts rather than the carbon ones that were in the video

[@RCFPVSTL]

Great content!

[@willpowerfpv3246]

The f5 split mini has 20x20 mounting. It's a nice looking for frame, too bad I have too many 5-inch quads. Thinking about the f3, though..

[@nuno2200]

Hyperlow Bside frame seems pretty interesting, looks like super versatile platform.

[@MysteryD]

For the record... if you're super careful you can drill out the M2 holes and set it up for M3 stack screws. You just need to make sure you have M3 press nuts on hand.

[@SkyweaverFPV]

Huh. I might do that

[@brett9152]

Wish I would have thought about that

[@levangugulashvili1296]

[@Quadbot4]

The Quadmula Siren F3 Split is my favorite frame these days. 🤖

[@CarbonGlassMan]

I use double sided sticky tape between the TPU gopro mount base and the top plate. Then I use a metal washer on the 4 screws that hold the tpu to the top plate. I haven't lost a gopro mount yet.

[@jas-FPV]

Packaging has too much plastic ☠️ And a tip: there are silicone mats to use in your car to prevent things sliding of the dash. Cut up, they work very good as battery pad

[@Selph_EU]

Yup. That's a nope for me.

[@DylanBogusz]

The shipping is the kicker…

[@icemaniceman5738]

Nice vid. I have also the frame and it’s very very great

[@AdrianoCasemiro]

All I use for battery pad is a good velcro strip. Cut to shape. Soft side on the battery, hooked side on the frame. I've been using these for years, and they're also cheap.

[@brentonasmith]

Same, rock solid approach

[@baptiste_nonat]

if 20x20 mounting for esc and fc is something you want, just pick the "mini" version of the frame. it's the same frame with 20x20 holes.

[@JoshuaBardwell]

Oh dang I missed that. So the mini version doesn't have 30mm mounting?

[@baptiste_nonat]

@@JoshuaBardwell nope, that’s the only real difference between those 2 frames.

[@josefdahari]

​@@baptiste_nonat it's slightly lighter and bit smaller. They are both nice. The mini is crazy light

[@baptiste_nonat]

@@josefdahari yep, just saying it’s the main difference but you’re right.

Joshua you’re an intelligent individual. I’ve been watching you for almost 7 years get you a one eight drill bit drill them out with a regular drill. It may take you a total of two minutes did you get mount him three bolts come on man you’re the smartest guy I know and I don’t even know you I’ve talk to you about five times come on brother talk text. I’m at work.

[@chrisbee5481]

Racers crash hard and prefer M3 nylon screws, not just because they are light, but because steel screws tear the stack appart in a hard crash. The idea is to rather have the stack tear out, than pierced by the stack screws. I use two nylon m3 and two titanium stack screws for weight savings. Can't find 20mm aluminum stack screws.

[@jwhitaker81]

I think Speedy Bee had the best take on frame related vibration isolation with the insert in the Master 5. Man, what a great frame. JB you should really take a look at it. I've beat mine to crap and it has held up well.

[@califpv]

dude, that was the worst idea from that whole bus frame

[@chrisbee5481]

JB talked about it in a live stream. He says the FC soft mount integrated in the frame is a bad idea.

[@jwhitaker81]

@@chrisbee5481 I saw it, he gave it hell. I think maybe he was a bit hard on it and my BB results speak for themselves so...

[@peeetah]

I really like the soft mount m2 screws with the silicon, that and the rubber gummies have really given me nice resonance and minimal vibration to my flights. Always super smooth. And with the camera mount they actually have a TPU soft mount for the O3

[@devilcfpv2621]

You have yet to ever mention the GravityLossFpv frame, the GRL Titanium Pro 2. The 2 frames that you named at the end of your video the fly fish and the rotor riot tanq. I have seen both of those builds and i just know i would break them. Im a concrete and metal beam basher and in the past 2 years of flying GRL i have only broken 4- 5” arms. Which is freaking awesome. Now it is a Ukrainian made frame but the innovation and time that went into designing these frames are just terrific. They really never break. The other frame that is absolutely indestructible is the KINfpv Atlas v3 titanium version. I flew one of those for 8 months never broke anything but i did sink it into a pond and just haven’t bought another one yet. I say these names because i know alot of ppl who dont like rotor riot in the groups like on Facebook and stuff so these are extremely great other options that really are indestructible

[@grampafpv8013]

I have bando bashed this frame a ton of times now and never bent the stack screws so if your freestyling in parks and wooded area's like i also do i just break prop's and get grass all over it. Joshua build it up tune it to your style and fly it cus i think your going to want to fly it all the time it fly's so good and I'm really not sure why i have always flown true x frames and not squished x frames but after flying with this frame now for a couple of month's i don't want to use any other frames.

[@MysteryD]

Oh! And * another * thing... the 3D prints that come with the Quadmula frames are some of the best I've seen included with frames, ever. Clean prints, durable material. Very nice.

[@keithcarpenter5254]

Iirc, ummagawds frame was tuneable by dint of different shure hardness rubber lord mounts, which separated the frame sections, so there is a precedent there. 🙂

[@MysteryD]

I agree. So long as they can keep churning out super precisely machined carbon parts, I'll keep recommending it.

[@RandyCAstleMPM]

Great review! I love how you articulate all of the little details, and weigh the pros and cons of each component and design 👍👍.. I have been flying the Dji FPVD for a year now. I want to make the jump to full fpv, what controller do you recommend i start with? And do you think i should build one or just get a prebuilt? I am a tinkerer and pretty good with my hands but iv never soldered. Guess i need to learn either way but i appreciate and respect your recommendations. Thanks JB Randy, MD

[@DarrenAllatt]

I'd be interested in your Blackbox Log.. if you have 2x F5 Split's on one, remove the pressnuts and drill out the M2 to M3 using your Dewalt drill

[@YorkyPoo_UAV]

I've always used m2 stack screws and never had an issue. Thought it was the norm.

[@moblades1]

While I think the frame is decent. The m2 stack screws and narrow body sections will keep me away. I've thought the trend of narrow body plates was a bad idea long ago after getting FC or ESC jackedin a crash and do not want my VTX overhanging the sides either. Plus now that we have the 03 wide AF cam, that narrow trend now has all the frame designers adapting and redesigning. JB, do you ever miss your Banggod? I mean look at when it was designed and it still fits any cam and VTX combo out with good protection😉

[@P.G._FPV]

I am not a fan of the main battery leads hanging out the bottom either.

[@abertheham]

1:49 “I’m gonna figure out something to do with that; there’s probably a use for it.” Me to my wife every single time. I’m gonna have so many awesomely packaged things someday.

[@DRONEPOISON]

You nailed it on the head with those stack screws, I bent mine multiple times in hard crashes, and had to call it. Moved on. Will work great for a lot of people just not this guy. Camera plates drove my nuts too

[@MurdersFPV]

Really appreciate you taking the time to review the SF5. If you think the first impression was good with the packaging and build, wait till you fly it. 😉

[@JoshuaBardwell]

But why M2 screws!

[@MurdersFPV]

@@JoshuaBardwell I know I know. All I can say is this frame is great to tune and with ample clearance for the strap to move plus an Ummagrip battery pad, I really doubt you'll have any issues with the M2 screws. The bends in the stack screws come from the battery strap getting caught on the stack screws and the force of a battery ejecting.

[@MysteryD]

@@MurdersFPV 20mm clearance means a handful of stacks are out of the question (looking at you speedybee v3)

[@MurdersFPV]

@@MysteryD Very true. My favorite combo right now is the T-Motor F7 Pro MPU6000 + Foxeer Reaper 65A 128khz ESC.

[@MysteryD]

@@MurdersFPV quadmula contacted me because the couple I built for customers had arms wiggling. Explained it was a QA issue with machining tolerances, then sent both me, and my customer, brand new frames to prove they fixed the issue. I found that to be a superb pr tactic on their part. Own your shit, fix mistakes, and show people the change. Perfect.

[@likwidkool]

I’m not a fan of the M2 stack screws and the press nuts in the middle. They get in the way of the esc plug and I need orings to raise it up making it harder to fit the stack. Flies amazing though. Would love an M3 version.

[@drew-ie9xw]

Car guys will recognize that to be a shammy towl container 😊

[@ninmarioscc]

I have that frame. The 3d printed parts are very good. The dual capacitor 3d printed holder is nice as well as the 3d printed arm ends But that it's not mentioned on the video the pressed nuts came installed on my frame. I would like the option for a 20x20 stack.

[@steamvogue]

Mini is for 20x20

[@SYNAPTICFPV]

Would really love to see your thoughts on the GRL gravity loss Pro 2 titanium. recently purchased one and man oh man solid frame 👌

[@Bruno-cb5gk]

I think the second plate below the camera is because otherwise you'd need 27mm standoffs.

[@JoshuaBardwell]

Ohhh that's interesting.

[@TheRoybert]

Non straight edges are to dampen vibration. Bardwell just guessing... The insert is called a bushing.

[@3DKreateFPV]

Jb, can you do a review on the Craftedquads Freshman frame?

[@olorf]

I do like those M2 stack screws! It seems to me that if something has to give, I'd rather it be the stack screws rather than the FC or ESC.

[@skyrotfpv]

Great chamfered carbon as well as precise 3D prints. I love the Quadmula Siren F5 and F3 split frames. The only weak point is the battery straps.

[@ashd1930]

Great breakdown and review! Can anyone please tell me whether the props come into view if using a GoPro? I'd like to try and use the frame as both a Freestyle and Cruiser (with a prop change and tune swap). Would love to see a Deadcat version but maybe that's not what they're about. TIA.

[@TriMeX1987]

The 03 version has softmount 3d printed front plates.. so these are not for the 03 with the faded part. Also I have only just build the frame. Still need to assemble all. I wonder if m2 is not a better choice... I rather have stack screws bend... that I can replace than have the force of a crash get into my stack... like a crash zone in a car if that makes sense. I am curious what whould your pick be in the same weight class... the tank is kind of the opposite offcource. But lets say a frame that has all the same basic screws and stack screws.

[@bloatedgoatfpv]

Where do you get the aluminum sleeves you use on GoPro mounts?

[@Fpvfreaky]

Joshua Bardwell, is it possible to make a tri-copter out of a quad copter bored that has only got 3 ESC is working on the board. (Aio board. ) If so I think it would be great video content as I’m sure a lot of people have Boards that they want to resurrect. Thanks man. Really appreciate it. Lou

[@chadstinar7621]

Can I assume we have to trim a little more off of the silicone stack screw sleeves in order to install the nut on top? This wasn't shown in the video because JB wasn't installing a stack, but there has to be something securing it, right? Also, I suppose we could use regular M2 gummies instead of the included sleeve.

[@JoshuaBardwell]

Yeah good point.

[@smithe68]

I’ve never seen anyone mention this frame but I’ve been eyeballing it lately. Heck they are selling an O3 build on that frame right now for $470! It looks to be a solid looking frame that could take a bit of punishment.

[@lunaticfpv17]

@Erik Smith I actually bought that kit and I'm certainly liking it so far. All it needed was a reciever and assembly. A full O3 quad for $485 certainly isn't bad! I liked the frame so much that I bought 2 more 😅

[@c666viper666]

will there be the O3 version of your signature frame soon? :)

[@MadDragon75]

16:43 I build mine with the power wire like the smaller image but I use fire resistant shrink tube over it to prevent the wires melting from the Avatar VTX & it gives a protected layer and rigidity between the wires and the carbon top plate. If you're not concerned about the weight, I recommend doing this.

[@JekleFPV]
