Fractal Engineering F75 & F65 // QuickSilver // Whoop Improved 

Hey Nick awesome review! I'm glad you've attributed the credit to QS as well as the frame; I do believe both go hand in hand and it's definitely helped getting the most out of this platform. A few details I'd like to add, - Both F65 and F75 measure exactly 65 and 75mm motorpost to motorpost (TM). Only the stance was widened to fit the cam between the front ducts! - The cam angle is adjustable by friction; you may set it how you like it and it should stay as is. The extra notches are only there to increase friction if it loosens up over time - Lastly the stack screws are indeed self tapping and might degrade the CF after many cycles, but a drop of CA glue will refresh it enough to go a long way, annnd... - The bottom plate is unofficially lifetime warrantied, so if you ever manage to break it, reach out to me and I'll fix you a new one ;) Thank you for taking your time to share your thoughts on it, thank you to all the pilots that shared theirs in the comments and a big big thank you to everyone that supported us, my wife and I, throughout this journey! Have a fantastic holiday and happy new year!

It’s unbreakable. Like no joke these things are STRONG.

Best BnF hands down!

Hi Nick, Thanks for the kind words on Quicksilver, i feel you got the gist of what we are about pretty much nailed there! The firmware itself is not strictly micro centric, i fly it on everything, be it whoop or 5in, however many of the core people, including me, are micro enthusiasts, so it might have a slight bias towards them.

Had never heard of these. Thanks Nick for the info.

Great review as always Mr. Burns, thank you for all you do and happy New upcoming Years to you and your loved ones Sir 😊

Good to see you lookin good, Nick!

Great flying you are shredding it Great stress test

Hi Nick, Those look great. I like the 75, thanks for the video and information.

Nice review Nick, love your honesty on this review. Very crisp flying teehee.

Fantastic flying and review, Nick! 😃 Pretty fun little quads! I really liked them!!! Stay safe there with your family! 🖖😊 And happy new year!

Oh man it’s so cool to see the Brds/ Bella/ Yves/ Heads slaps in the thumbnail!!! The F75 is one of my favorite builds of all time. Competition winning one might say 😅 Mine’s got the heavy but indestructible 1002s and fpv cycle board. Only whoop I’ve never busted a part on. Absolute tank. Everyone should give ‘em a try. 😎🙌

The fractal 75 quickly became my fav whoop. I recently posted 2 clips on it on my IG. Another great review NB! Always 🔥

Nick, your flight skills is awesome. Like flying to the forest of Endor. Best flights so far.. 👍👍👍🤙

Solid flying! 4+ mins full speed and did not even crash 👍🏼

DVR looks great on these!

Love the 75mm, built it up almost exactly as the BNF except swapped the Foxeer Pico in for the camera. Same quicksilver preset as Heads Mobthicc and man I love it. After a few months of flying nothing has broken yet!

Got the 75 conversion kit for my mob 7 - I run it ductless outside and it's a little 1s Freestyle ripper! I love it

Hi. I am flying a 75 based on a betafpv FC and a happymodel open vtx. Flies amazing. Tried it both as pusher and normal with the original thumb also.

Love my fractal 75. It's in liftoff micro drones as well to practice and find ideal rates.

I've been flying the 75 frame without ducts and with happymodel 1002 20000kv motors it's an absolute lil beast. happy new yr 🔥🔥🤘

Another thing about quicksilver is that it's codebase is also very clean compared to betaflight etc.. with lot less legacy baggage..., very easy to understand and modify to your needs..

HOLY CATFISH!! I'm going to start using that one! Love it lol

I switched to QS few weeks ago and I already know I won't go back to BF even if someone pays me. Propwash performance and tracking are just outstanding on all of the builds I tried. I highly recommend all whoop pilots to give it a spin! It's worth it! Kudos Quicksilver Team

I'm planning on picking up the HDZero version of the 75 in the next couple weeks when I get paid again. They look amazing, can't wait to fly one.

I just got one of the 75’s you were spot on it is the best whoop I’ve ever flown on silverware. Light is right when it comes to this type of quad. Overall a Great review and one of the reasons I bought one. The same with your 2” toothpick recommendations . Tks 2S setups.

QuickSilver is pretty good,it has that anti suck to the wall washout feature. I remember Silverware , that was on my very first whoop 6yrs ago that was a betafpv beta lite 65. At that time it was only 40 dollars.I Hope you had a very merry christmas, And A soon to be great newyears.

Thats the cleanest analog video I've ever seen!!

i ordered the 75mm frame with the extra 2mm bottom plate so i can build a cruisy 1s ducted and a 2s ductless for freestyle and just had them show up in the mail today. i can’t speak on the bnf myself but the frame itself is incredibly solid feeling compared to any other whoop scale frame i’ve bought and i’m super excited to get them built up!!

So sick to see my stickers on your video! Been flying the f75 since before it was released and its still my favorite whoop to fly! Even using bf it feels so stable and locked in!

Nice review Nick! I just bought an F75 BNF with the BT2.0. Really cool how they soldered on the BT2.0 to shorten the wires and shed some weight. The connectors in your review don't have that though. I noticed the increased stability of the Quicksilver and F75 preset tune right away, sometimes it feels like angle mode but it isn't. It's different but I like it, definitely helps the quad to go where you point it, very confidence inspiring. I had one issue, emailed Fractal but never heard back, maybe Facebook would have been better. Anyway, mine wouldn't roll over in turtle mode, because the props weren't reversing. Studying up I saw Quicksilver has an auto detect for flip if it is armed upside down, cool feature, you just turn it ON in Quicksilver. Oddly, that works fine, props reverse, quad flips. Cheers!

I build mines 75 8 months ago and to me this is the best woop you can fly. for you to appreciate you have to fly it outside It's incredible.

Fractals for the world!!! You won’t break it, I can’t and I crash the hell out of it.

Damn that was an impressive flight on the 75 Nick. My stomach flipped and my motion sickness skills are up there.

Best whoop i have ever flown

Love Fractal!!!

Oh yeah. Small spaces can work. My place is a 20' x 20' one-bedroom apartment, and my daily driver's a 100g AUW, 2S, 2-inch whoop. Giddy up.

Lovely review Nick, as always. Thank you on behalf of the team for your kind words on Quicksilver too, it's come a fair way since you last tried it. If any of your subscribers or commenters need any more info on Quicksilver I am happy to check by and answer them. Those Fractal frames are absolutely fantastic in design and performance, I fly my F75 and F65 really regularly. and hard with no damage so far. I will be converting the F75 to HDZero soon using the X12 lite fc and a set of longer screws and custom gummies from Yves. Happy flying and I look forwards to your 2023 videos.

After flying my F75 I doubt I'll ever fly any other Whoop. Yes, it's just that good!

I cannot stop flying the Fractal 75 since I received it. I think I’ll try Quicksilver although it’s flying really good on BF! Great review Nick!

Love my fractal. Was thinking of getting a 2nd one, but seems mine is bulletproof!

Thanks for the Vid. I ended up with the 65mm frame kit. I used the Happy Model elrs Diamond board, Beta Flight 4.3 and some happy model 702 26000kv motors. It reminds me of my old 350cc 2-Stroke sports bikes from the late 80's. I don't fly it as much as I'd like, even at the lowest camera angle (for a newbie like me) it's fast, but as my skils improve I take it out more ovten. I love the feel though, tried a few canopy's from thingaverse, I'm goign to go back to the one it comes with (it was fun to experiment). This Channel got me to Infinity Loops and I saw Heads fly this and ordered one. I think I'm going to order a 75mm bnf in the new year. I like both 65 and 75mm formats, and I'm also curious to fly one as the builder intended. Highly recomend these kits, I can only guess the prebuilt quad is amazing (Watch the video to see how he get's those motors connected, really takes his time and puts a lot of pride into these builds, amazing). Enjoy both Fractal quads, it was great to see you fly them. One day I hope to rip around my condo like you do, slowly getting there. Cheers!

I've been looking for a whoop that I can tune up to perform indoor freestyle for years. It all started when I joined IGOW a few years ago and started learning flippy floppies on an underpowered betafpv 1s whoop. I had a tough time of it but was hooked. The never-ending journey began, trying to replicate the feeling I got with a 5-inch quad but indoors with a whoop. Following Heads at Infinity Loops and CiottiFPV I found the fractal frames. I added weebleeds 28500kv 0702 motors, a full-size happy model 5 in 1 aio elrs board and some bi blades. Cranked the tune-up in betaflight and wow, this thing flies on rails. Enough power to catch my mistakes, stiff enough to take an aggressive tune. I love it. Thankyou! I tried to flash quicksilver but could not bind with my elrs tx (running v2.0- elrs). Gave up. Pretty sure I'll need to upgrade to v3 elrs on my tx (and all my rx's) and this should work. Looking forward to feeling the new firmware.. Great review as usual Nick!

Best Whoops EVER!

I already have the Fractal 75 frame! Waiting on the Avatar Lite kit to arrive to build! Nice to see some more information about Quiksilver. Infinity Loops talks about it, but there wasn’t much more information I could find about it.

I have both 75 and 65 and in my opinion the best 1s frames you can get today!

excellent review sir! I love my fractal builds! I have 2 mobthicc Heads builds and a fat boy x12 on the 2mm plate with crossfire and a true rc antenna for 75mm builds 1 65mm and I'm currently waiting for a 65mm bnf. I'm hooked on the fractal frames. highly recommended

Funny, I put Quixksikver on one of my Whoops last week and after 5 packs decided the switch the entire fleet over, it just flies so well and I’m fed up with having to replace frames every week (the Quicksilver whoop was the only one that didn’t brake a frame last weekend). The only thing I think that is better is crash recovery in Emuflight works better, but I literally don’t care about that as I’m not crashing so much with Quicksilver lol.

Great review, great whoop. I'm flying on a F75 on x12 and various 802's. After a hundred packs or so... Tracks amazingly well, i think the squashed-x really shines here. Also tough as anything. I have broken ducts, all v4 mob ducts, always at the joint by the motor. It's3.99 for 4 so no big expense and i rip hard and crash hard. I use holders for 450 and put a rubber band across extra for 300's. I wish the spkies where just a little larger to hold bands better. The tpu works well, but only for its exact battery size. honestly think a rubber band is quicker when you're burning through packs. Also lost the self tapping screws for the fc after repeated abuse, just using 2 now. Camera mount has held up 100% Definitely love this quad and the clever design that's gone into it. There is a vid of mine flying on my channel, check it out.

I really like this frame and its durability! I ordered the 75 frame last February and haven't break anything ever since! This is my first whoop recommendation at the moment, especially for beginners. I only had two small issues with it: - The battery always slides out of the mounting loops in a crash, so I have to use rubber band to keep it there, which adds another 1g or so and the frame is not the lightest one even with the diamond board. So I wish Yves makes a version 2 of this frame with the battery mounted from left to right instead of front to back. - When I first received it, I just used a FC from my old whoop. It was BetaFPV 1S AIO. And the problem was that USB port was sticking out the bottom too much, so I couldn't insert the battery. I had to add extra washers underneath the FC to lift it up a bit and also some rubber pads on the bottom side of the frame to add extra space. Having the battery mounted sideways would've also prevented this issue. Apart from this - the frame is amazing and I guess unbreakable. I crashed it a lot and pretty hard and I only replaced props so far. I use it with happymodel 0802 19000kv, a diamond FC with ELRS and a Foxeer Pico cam. It's flies fantastic and gives you much more confidence to fly aggressively. I fly it on Betaflight 4.3 though.. I tried Quicksilver and it flies great on it as well, but the biggest issue for me was that I killed two brand new batteries on the first two flights. I don't know why. I set it as it was recommended by devs for 1s, but still ended up with the whoop falling at some point because the voltage suddenly dropped to 2.5v. As I can see you kind of had a similar problem. Another thing was that I couldn't make the 16:9 camera work. The image was squeezed to 4:3, but OSD fonts were ok, so I guess it is something with support for 16:9 cameras and there's nothing in settings or in Quicksilver docks. So I rolled back to Betaflight and absolutely happy about it. I don't see that much of a difference in flight performance, but at least I have much more experience with it and know what I need to tune and how. Maybe I'll give the QS another try one day, but I'll use BF for now.

Looks fun...👍🏻🍻👊🏻

woah! never heard of these guys, or the firms ways but, wow...the 65mm looked like it tracked and flew super nice just from seeing the dvr. ill def be going with these guys with with my next few micro purchases.

"just entre the passphrase into the Gouwee" ^^ took me a good minute

Hi Nick! I ordered the 75 with 25000kv and x12 a few days ago. It will take some time to get here to the Netherlands.... I can't wait to get it!!!

Not sure if I posted my input on the 65 size but here’s my input excellent out of box the acro tune is like flying my 3” quick silver or beta that’s been a preference from the birth of both I race whoops and I bought this cuz I kept breaking my mob6’s so I heard the fractal was way more durable and thus far it is however I fly weird rates in angle mode and couldn’t get it to feel like my mob6 useing quick silver so I dumped it and put beta on it and it flies just like I’m used too I did save the quick silver firmware though cuz in acro wow

My whoop of choice now running hdz and will be posting videos of it once the weather improves here in the UK. Getting lots of indoor practice in for the meantime. Great and fair review though Nick 🎈🤡

Have two quicksilver Mobthiccs, they're fantastic. Those frames add more confidence, knowing you're not gonna have to replace a broken frame, only maybe just a broken duct and that's a piece of cake.

I have the x12 board, I use it on a 2s 3" toothpick, it's been amazing. I put betaflight 4.3 on it, rpm filtering, and took 3 packs to tune it BEAUTIFULLY. Auw is around 85g on 450 2s. 79g with a 350 2s. I'm using 1204, 8000kv.

My mobula6 with 0802 19k is acting up since i did the conversion. It has almoat no power, and hovers at over 5a. Im lucky to get right at 2min flight. Seems like its under-propped. Idk Edit: it has the original bi-blade props that came with it. Ordered some gemfan 3/4 blades. Hope it helps

Yo Nick! I had to laugh, when you said, you can hear the warnings and such and that it´s very annoying to you. Here the same...😅 Basicly everybody have this. The ones more than others. It´s called "audiovisual integration", and actually it´s a cool phenomenon. It shows us, that sounds can getting created by our brains, only with visual waves. The animated gif, with that jumping voltage towers, are a good example for this. What all in all means, that there is no existing sound anywhere if a tree falls in the forest, or such.... ...until the waves collide with a brain.

It’s a great whoop, I got the fractal 65 frame with the happymodel elrs F4 2g4 aio on 0802 25000 kv and it flies great on betaflight but I’m gone switch to quicksilver later.

I have not flown the BNF but I moved a Mob7 with tiny whoop 25000kv motors onto the fractal frame and it might be by new favorite backyard/play set ripper.

The open board is nice, but parts may break ...The diamond board, in my experience, needs a good batterie. If your batterie is old but works with other whoops it can cause problems with the diamond board.

Fantastic job on both flights and the review on both frames Nick👍👍😎😎👍👍 Hey many mah's was you running on both the 75 and 65??

It's nice seeing a treadmill used fir something other than a cloths rack lol.

I have both F65 and F75, and they are both tanks! I have crashed and based them both and they keep on ticking. Word from Mr. Fractal is that the slap sheet has a future purpose with the number on the sticker

Hi Nick, Fractal frames are my recommendation to anyone wanting to whoop around. I had less AIO failures, less broken whoops... but as many motor burned and as many camera destroyed... Some comments: The battery holder gets quite stretched over time. I have many batteries spanning from 450 to 530mAh and some are wider than others (by 0.5mm?). That's enough to make the hold not as good over time. I'd love to use some rubber bands instead. I'd love to toilet tank my batteries too :) Mr. Fractal, maybe a slight change for the next iteration? The camera holder is surprisingly good, even with ANT lite cameras that have the plug. I'm using the old 3 blades props that gave you more efficiency in an old video. I actually prefer these for indoors, as you can turn more aggressively. As for the diamondF4, I had one with horrible video noise coming from the factory, The issue was in one of the caps immediately above ground pin for the battery. It was not properly soldered in the factory and I could see the lack of solder on one end. Happymodel asked me to send it back to them for repair, but that costs a bleeding fortune from my place... Eventually I repaired it myself, but that was a heck of a job... Within maybe 15 flights it died. I contacted HM again and they agreed to send me a new FC, which was really kind. That one has been flying fantastic ever since (board dated November 22)

this is the next whoop on my list when i break my current go to’s. Only problem is my current builds haven’t been breaking! It’s insane 10weeks on racegow on the same whoop…

The 65 was on my list of frames to buy, and it still is ,but I put the mobula6 on my wish list, and Santa brought me one, although with the 19000kv motors instead of the 25000, but Santa did well.

Hey Nick! Love the reviews, but I have a little request: when you say that a board has built in ELRS can you also let us know what interface the receiver is using? I know that on the HaMo Diamond it's an SPI, but a lot of the newer boards(like the GOKU Versatile F405 2S 12A AIO) are using a UART to avoid the ELRS SPI issues. I know BF4.4 fixes the issue, but it's probably going to come up again at some point so it would be nice to know without having to dig around the net.

I’ve been running Quicksilver exclusively for a while now - it is by far the best firmware for angle, though I know a few people have switched back to Betaflight for acro due to the lack of crash recovery

A waive to everyone who checked their phone @ 9:09 in this video because of the notification chime.

Those look nice. I wonder if I fly outdoors you could lose the ducts? I broke(got run over) a cockroach and the carbon fiber piece was saves and wondered why there’s no >75mm toothpicks

Dang it! I just bnought the M7 1s ELRS. Turns out Im always on full throttle in turns, since I love racing in the house like you do. Guess this is the Whoop for racing to get? Is there something better to buy for only racing a tight course?

Thanks for the informative review. Serious question: How do you keep from getting motion sick? I've been flying a bit indoors lately and can only manage a couple of minutes before nausea sets in. Stay well.

woot woot!

I built the 66 Mm. Used the f4 full sized board. Had to flip it upside down. Figured out how to turn it 180% in bf. But now I have to rearrange the motor order. Having a problem with that.

16:02 I’ve had 2 x12s go up in flames. Literally… They were on the mob7 1s hd. If you HV lipo those with bt2.0 the vbat lights up the blackbox logger and the whole thing starts on fire.

Nick, have you tried flying the 65 on 270 mAh 1S instead of 300? I followed AngryDon recs, night and day difference! Felt like a different quad.

Happy new year 2023 bro 🎉🎊

TIL: "Holy catfish!"

Getting the 65mm frame to build with the crown 65 frame, what do you reccomend for parts? I was thinking screamer motors and a runcam camera, but idk what i should get as for a aio, i run elrs.

The sound of the motors on this whoop, or 0802 motors in general, compared to the 1002 drashark motor sound; which one sounds more silent to you?

just get about 2:30min flighttime with my fireflywhoop65mm whoop on 380 gnb. stop flying at 3,3V. how low can i go while flying so that i end on 3,5V? have a nice new year!

Than, if I want just indoor flying, less power but same agility the 65 could be a good choice over the 75 ?

Interesting frame I don't have them neet to see more of them.

I'm wondering do the ducts really need to be on there? Maybe you can take them off and fly them for a week and let us know how it works out!

Maybe this is a dumb question but is it possible to use the 75mm frame with HM 1102 1000kv swinging 2023 props and the X12, I'm trying to build a TKS rocket race but I don't have any way of getting it for a reasonable price in Australia, it would be like 50aud shipped for one :( any other recommendations on a 2 inch toothpick frame that's available on AliExpress or Banggood I've looked everywhere

i still cant figure out how to bind up the x12 unfortunately with elrs. ive tried everything multiple times and it just doesnt want to connect

What's another really good ducted 75mm whoop most similar to the fractal 75?

Hey Nick, any chance you could build an HDZero F75?

I've had better luck with the full size Happymodel ELRS flight controller. The Diamond version is hit or miss. Alot of people, including myself have experienced bad flight characteristics and excessive electrical noise with the Diamond board.

anyone knows how to keep the motor spinning when arming ? my motor not spinning when on 0 throttle,

Hmm, hadn’t heard of Quicksilver - is it significantly different than emuflight?

Hello Nick, Have you started flying Analog on HDZero goggles yet?

Wow! Mr. Fractal doesn't want too much for his BNF's, does he?! 😲🤪 ...And no coupon code on those, either. Damn, the better part of $200. Guys, just build up yer own! 😎🤘 My Fractal Frames R Fantastically Fun! Last time I ordered, you could buy the thin or thick frames and add the opposite, thick with thin carbon fiber, for a lot less money if you bought them all at once. I didn't look to see if they are still selling that way, but you get a much better deal if you add that second frame with the first one. Anyway, look into that! Highly recommended! 😎🤘 Well done video, Burnsy! And a Happy New Year, Bro! 👍

How can you not compare these to moblite7/6? These had to be compared 😔

I've had 3 X12's, all defective. :(

What are alternative 1s 450mah Batteries for the none US people?
