Last week I was asked to repair a Cinequad, Diatone Taycan. When I came to test fly it I was quite enamored by how nice and stable it was to fly slowly around my property. The noise however was not all that well received by the natives.
So rather than go for a full sized cine-quad I was wondering if anyone had experience of smaller less noisy alternatives and could share some recommendations?
I recently bought a cinelog25 after seeing some footage posted by @andreab
I use mine with an insta360 go 2 but they can be used with an SMO 4K, Gopro6 lite and Gopro8 Lite instead.
Iām still getting used to mine so have limited footage to share as the maiden flight outside was only yesterday.
First impressions, its loud but less loud in comparison to other cinewhoops - itās agile and has a good amount of power.
Iād recommend as a first cinewhoop user.
Agree, itās a bit loud as it has to carry additional weightā¦ so props have to spin faster.
My advice is to buy a set of 5 blades props for comparison (I went for the yellow ones):
Iāve also been looking at stuff like this. I was wondering about the new MK2 version, which has different ductsā¦ itās those that make the noise.
I suspect the default ducts may still be noisy, the holes making a whistling sound. But you get an alternate āclosedā set in the packageā¦
The other one Iāve heard good things about is the GEPRC Cinelog 25.
Nick Burns has reviews of both and many other small dronesā¦

Good shout. I also have just received some of the 5 blade props.
Thank you, everyone, for the replies and great info.
The first thing Iām taking away from this is I donāt have a clue as to what Iām talking about. Now I know that all Cinewhoops are Cinequads, but not all Cinequads are Cinewhoops.
The Diatone Taycan is back on my bench again. After I gave it back to the owner he wanted to install the LED ducts, and in doing so he shorted out the 5Volt and 9Volt lines on the MambaF405Mk2 flight controller. He wired the LED signal wire to the 5Volt rail, and the VCC wire to a NC pad. Iāve managed to resurrect the 9Volt and 5Volt rails but I fear he may have permanently damaged the BF LED signal line, as no matter what I do I just canāt get the LEDās to light even though the regulator board for the LEDās is outputting 5Volt.
Anywho, back to the original topic.
The subject of the 5blade props. When he first dropped the Cinewhoop off for me to fix (heād wired up the receiver arse about face) it didnāt have any props on. Once I fixed his dodgy wiring and cleaned up the rest of his soldering I test flew it first on 4Blade props. It flew OK but lacked precision. Installing 5Blade props transformed it and I thought the precision was now near surgical. I wouldnāt say the noise generated by these props was quieter but it was more pleasant in a tonal kind of way.
Currently the choice of Cinewhoops is a little limited, as is the choice of all FPV quads types in general, due to the current semi-conductor shortage. Iāve also noticed a price increase in most flight controllers and ESC packages, no doubt related to component shortages. On the upside I may end up inheriting this Taycan as itās owner canāt fly quads, even though he has quite a few (Iāve repaired those for him also).
Isnāt it always the way? I start thinking I have enough drones then find a reason to add to the collection. Cinewhoop? Why the hell not?
Less of a high pitch whine?
Thatš
And in musical terms itās like comparing a diminished chord to a major chord. Diminished chords create tension, but if followed by a major chord the tension is removed and the progression is resolved.
So the frequencies generated by a 4Blade prop in a duct sound disconnected, but those created by a 5blade prop are more harmonious. Itās either that or my medication is twisting my melon again.
Nidge, Is there anything you donāt know 
I just found thisā¦
Looking in my bits box I found that I have everything needed to make it except a stack.
Soā¦ Iāve bought one of these:
At Ā£33 posted it was hard to keep saying ānoā (which Iāve been doing for a while now)ā¦
I was concerned about the low amperage, but I just checked and my original 2" 3d printed drone has a 6A ESCā¦ 6A! Thatās nothingā¦ itās been working fine as well! In fact it flies great!
There are days I canāt find my car keys. But thatās because theyāre in my pants, which I often forget also.
That was exactly my thought process. Iāve rationalised my numerous fpv drones by telling myself each one has a different use - speed, freestyle, cinematic, long-range and small spaces 
Well, it sounded right in my head anyway!
Interesting about the 5 blade props. Iām going to change mine over later today and listen for the difference
I shouldāve recruited you for the āGibbetā project. 
I have a BetaFPV 95X (v3) with 5 blade props. I agree, itās a nice thing to fly and I can slowly potter around through tightly packed trees and other tight gaps quite happily. It is bonkers loud though. I think the ducts contribute to the noise, more than the prop configuration.
Mine runs 4S and comes can just about carry my āRuncam 5 Orangeā, but requires a noticeable amount more throttle (and noise) to do so. Itās more designed for the lightweight naked GoPro/SMO 4k/Insta 360 type thing. If I was buying again Iād look at something a touch bigger with a bit more grunt. Itās kind of pointless flying it without a decent HD cam on there since the whole idea of it is that it can capture lovely smooth cinematic type footage.
Thank you for the info. Iāve just finished repairing (again) the Diatone Taycan that belongs to one of the members of my flying club and had a quick test fly around my property, and to be honest Iām now beginning to think that the noise isnāt too bad. I did notice it didnāt like sudden surprise breezes though.
Iām more about the flight experience than the video results. Whatever video it produces would only be of interest to me, unless I was able to capture Aiden Turner (Poldark) then my wife might take a peek. That and my upload speed to Youtube is less than 600kb/s so any reasonable short HD video would take an ice age to upload.
Have you seen the happymodel cine8? Also sold by unmannedtech as the C2 Cineflea, 2 inch ducted, runs on 3S and is Ā£85. I have one and that runs a insta360 although it will run a naked GoPro.
If you just want to dip your toe in, you canāt go wrong for the price.
The duct scream is a thing but I tend to fly it indoor or well away from people exploring tree canopies. Wind is not your friend!
Thank you for the suggestion.
This little thing appears to tick the boxes I was wanting, small and relatively cheap, so as I had some other items in my UMT basket itās been ordered.
