I really like this build. I am a beginner mainly want a drone for nice, quiet cinematic stuff, not racing, so this sounds perfect! I wanted an Eachine Viswhoop but it looks like those are no longer available in 2022. Is there a complete kit of something like this one so I don’t have to spend months gathering parts? I’m not afraid of assembly or soldering as I have been building electronics since probably most of these guys were born…

For a simple conversion, try stripping the parts off the KT20 to the frame I have in this video. If you want something you can just fly, the CineLog30 is your best bet.... bit.ly/3yGPbsO

The NBD savage bee is pretty quiet. Could prolly work off of the 2s version. 43grams dry weight with crossfire and miniT.

[@AlbertKimTV]

Might make for an interesting conversion project

[@JohnMorawietz]

shorten lipo wires to dead minimum and loose the plug ends for bullets only (Im wondering if the lipo can work from the charging connector only so the red/bk wires could be nixed completely) lightening holes on the gp mount, cut a few of the prop guard inner legs, ca the inner most touching portion of the prop hoops, no iron fasteners (maybe twist ties in the center boards or hot glue only), you might shave another 10grams by then. You may be able to hog out the center of the main mounting plate for a few less grams as well. Probably the smoothest vid Ive seen yet.

Albert, very nice looking and more useful cinewhoop type quad. I see more use for this than the noisy things on the market and you're right, expect to see more of them on the market. Well done.

[@rocketrob3324]

Albert, A heads up, the Baby Tooth Frame listed as "alternate" (RDQ) must be slightly smaller wheelbase than the Sanchex Air design as the prop guards are to close to each other and either want to overlap (over/under) or it flexes the frame arm upward which put the motors negative cambered from vertical. Has anyone else noticed this? Or as @Macelius FPV suggests, I could chop off the inside of the guards - solving this problem and saving some weight.

[@AlbertKimTV]

See m posting on the Crux3 conversion. I cut the inner part of the guards off in that case. instagram.com/p/CKKkJ_qLA25/

Hey Albert, what’s the longest flight time you can get on something like this? What battery? I’m trying to identify a build like this for recon and intel.

[@AlbertKimTV]

If you're carrying the naked GoPro, you can go up to a 2S 750 and get close to 8 minutes flight time just cruising. If you need more, change the motors to 5000kv and go to a 3S 650mah. Maybe 10 minutes of cruising on that one. But the weight and noise level will go up.

Wow Albert this is such an amazing approach... What I dont get is why you dont start your own line of quads? This idea has so much potential...

[@AlbertKimTV]

It can be made to work but the results will not be as good because GoPro with ReelSteadyGo is very much superior.

[@niuind545]

If you want quietness It will be a little heavier, but a 6-blade propeller is recommended. The noise becomes bass and less noticeable.

[@AlbertKimTV]

I actually already tested that but found it's noisier than three bladed. Seems 3-blades is the least noisy for this setup.

[@twinturbostang]

If you have prop clearance, you might be able to zip tie the prop guards together for added strength.

[@AlbertKimTV]

[@ojkolsrud1]

Very cool! Nice design too! You're putting a lot of mass in the front of the quad though, do you feel that while flying? Does the two front motors become hotter than the back motors? With everything else being so light, I would probably try to mount the GoPro closer to the COG prior to adding it. Also, I gotta say, ReelSteadyGO is *almost* like cheating. I'm sure this quad, even with the damping, vibrates or tosses a little bit when flying, but your footage looks incredibly good and stable.

[@AlbertKimTV]

The motors don't get hot because the 26g naked GoPro is not putting any kind of load on those motors. The motors have way too much power for the weight. It's slightly unbalanced but nothing the FC can't handle and you don't feel it at all in flight. I'll post links to raw footage that has not been processed through ReelSteadyGo. You'll be surprised how smooth this flies.

[@ojkolsrud1]

​@@AlbertKimTV Cool, man. How do you compensate for that through PIDs? My 5inch is a little ass-heavy, and I see it pitching on throttle-ups.

[@matthew04101]

tri-blade 2.5" props are about the same as bi-blade 3" props. but smaller frame, prop guards = lighter weight, harder to break. just an idea. another thing, would you try 1303 5000kv 2s tri-blade 3" props like gf3016 ? just to see how it would fly. thanks for your hard work.

[@AlbertKimTV]

Because the 2.5 inch props have to spin faster to carry the same weight, they make more noise so I gave up on that idea a while back. I wanted something less noisy and less concerned about overall size. The 1303 5000kv motor on 2S would still fly but will drain the battery faster I think. Shorter flight time but noise level would be the same.

Nice job Albert, I like the approach. I was pretty close when I suggested in the previous video comments that it might be the crazybee crux3 with some prop guards ✌️. No seriously, I still dont get how the different constructors in the hobby always tend to forget how much benefits we can get from designing ultralight builds, and go the opposite way. At some point I even wondered if it wasn't a strategic marketing decision to design heavier setups so that they can generate higher margins from more expensive embedded components and lipos.

[@AlbertKimTV]

The reason is because there is constant pressure from much of the FPV community to make drones "indestructible". They must survive hundreds of crashes or they should not exist. I'm one of the few people who don't subscribe to this dogmatic propaganda. Fly what you want to fly. Screw everyone else.

[@flylow3457]

@@AlbertKimTV you're probably right, it's a good reason, however I do wonder if this supposed big pressure for extreme durability isn't much exagerated by the brands. If we look at the recent huge success of the flywoo explorer lr, for me it really shows that people interested into very lightweight efficient setups (at the compromise of less durability) isn't a niche market at all. Do you know if some of the hobby brands are planning to release a bnf ultralight cinewhoop like yours anytime soon?
