I had picked up some 1507 motors with the thought of reviving my Acrobrat Duo.  But then I got to thinking why not make a cine whoop which is what these motors are really catered to.  So I started looking at videos.  I always thought cine whoops were these goofy looking overweight flying foam thingies but started to appreciate their purpose - and safety.

So instead of the Acrobrat idea, I decided I'd build one as I've never built one, flown one, or owned one before lol.

I ended up on the Diatone Taycan MCX 3 inch frame because I figure if you are going to fly a goofy flying foam thingy, at least make it audacious and bright lol.  I'll be using new Lumenier 1507 Turbine motors, a spare T-Motor F7 mini stack, spare TBS Race VTX, and a Black Friday sale Foxeer T-Rex from Heli-Nation.  I'm hoping to get at least a couple minutes off an 850mAh 4S carrying a GoPro Session.

This will be interesting lol.  

these motors are made for a beefy 4inch xD
my idea of a good cinewhoop is more lightweight for a deceased gopro, why did you choose a full session and heavy 3inch parts over a lightweight?
you will use it for slow cinematic footage only or try to get some acrobatic flight with it?
intressted in your result and impressions

I think that most 3” cinewhoops are intended to carry a full size gopro hero 6 and above. The naked gopro builds are mainly in the 85-95mm segment?

Yup this is purely for slow cinematic. I will tune it in acro to optimize setpoint tracking and fly it in acro but I will not be doing acro moves. My goal is to get reel steady footage but without the reel steady lol. Also for the degree of safety and added confidence to fly closer to objects I would otherwise be scared to scratch up.

I had looked at the smaller Taycan 2.5 and even the smaller still Tina Whoop but I really wanted something to carry a Session. The 3 inch cine whoops seem to be designed to carry full size GoPros. I think my lipo might be on the smaller side though.

Yea I'm curious about this too!

mine is different xD
i use 1106 6000kv on kk 2840 props and 3s 450mah-850mah with a deceased hero6, i disliked 2,5" i tried first on the same setup.

i would suggest 3inch for a deceased gopro over a smaller size.

the gopro is switched to the other quad in the picture.

found a 3inch printdesign, someone with tuningskills should try that :-)

lol, I just tried printing that this week with ABS material - would recommend the version without the holes in the ducts - they make for a tricky print and also prolly ruin the flight dynamics of a ducted motor.

Be prepared for some ear piercing and embarrassing level of noise. I built one a while ago and noise was the deterrent from more regular use.

The latest IFlight Protek 35 with 3.5"/2203 motors looks interesting though. Much better flight performance from the video review, like a freestyle/cinewhoop hybrid.

Lol yes that was one of the things I noticed from the youtube videos. One of them was even straight up titled "why so noisy?!" or something like that.

lol found it ...

abs sounds specialy nice. "tried" means it doesnt work?
i would like pictures and a build thread :-)

Greetings,
I'll start by saying thank you to the few regulars, here on IntoFPV fora, with hundreds of "high value content" posts (as opposed to the 1000s of low S/N ratio ones - on better known or longer established fora), and apologize for my noise, as I seek to grow my knowledge.

I'm also interested in finding a ducted, smaller form factor, quad to fly HD FPV. I've been particularly enlightened by the tasty morsels, posted in different threads, about 'noise'.

I'm posting in this thread because, after seeing iFlight Protek's ducts, I searched on Protek before starting my a new thread, and this thread came up.

I'm puzzled! I read, in jasperfpv's post above, "... better performance..." and I think about all this published material about better performance on ducts requiring props that hug the ducts, duct design, ... And now I look at the Protek with 'ducts' that a partially octogonal ...!!??? So ... I gather it's more about having "prop guards" than 'ducts', per se, at this point. And bullnose props in a duct, as to noise, are akin to EDFs? And ducts, with close fitting props, are more likely to break something when you 'bump' something with your drone (than "prop guards")

So we tried "ducted fans" and found them to be noisy; So now we're moving towards smoother props and looser prop guards?

Inquiring minds continue to ask. G.

When I say better performance in my comment about Protek 35, I was referring to it's flight performance, not about thrust figure from the ducts design. With only prop guards and beefy 2203 motors and bigger props , it has higher cruising speed , ability to acro , less prop wash and less prone to wobble in windy condition due to the ductless frame. Unfortunately the bull nose 3.5 props used will be quite noisy too.


I had Shendrone Squirt V2 with cut down 4" props digging into the duct and later Diatone Taycan DJI build which has obvious gaps between the props and ducts. Mutefpv on YouTube did a duct design thrust figure comparison and despite the gap, Taycan maximal thrust is similar and a bit more than the Shendrone Squirt duct.

Anyway I just sold my Taycan yesterday. The noise and the wobble in the wind was getting to me. If I were to do it again I would try lthe Protek 35 frame and 2203/2204 motors instead of Ducted 3"/ 1408/1507. I think Kabafpv was the first person who advocates 2203 motors for Cinewhoop and IFlight has taken after the idea to do a different design. Cinewhoop market is getting saturated a while ago so they are doing something new to sell. Whether it will take off or not, it's too early to tell.


Not many online footage yet but here's a short vid of by a brave guy flying his Protek 35 in rain/snow.

Thanks for sharing. I appreciate the details in your description. It's enlightening. I came across that YT video on GetFPV's Protek 35 product page. That Quebecer has similar weather to what I have to fly in. Brave indeed! It's one thing to 'Trash' a 75mm around in that @#?%. I'm guessing the GoPro is safe, but even with conformal coating, it's expensive electronics to fly in that kind of weather!

I am trying to better understand that form factor for FPVing in HD. From experience, I know I enjoy flying the Mobula 6 inside the house. TheMob6 HD isn't as enjoyable. So, I'm trying to understand what I can expect at the Cine Whoop scale. As an example, one can contrast the Protek 35 to a TransTEC 130mm (2.5" props; or its smaller sibling w/ 2" props). I would imagine the Protek 35 much quieter, steadier, and having longer flight times than a (I'm guessing) screaming loud bumblebee!

I noted your comments about 'noisy' in this Beta95X thread. I'm hoping to find something quiet to avoid attracting unwanted attention. Perhaps I'm disillusioned.

So I continue to read up. Thanks again for the input, G.

Someone asked him on YT and he didn't even conformal coat the quad. A bit foolhardy in that weather haha. He was lucky or may be IFlight coated it from the factory.

Coming from a whoop or 2-2.5" , the traditional Cinewhoop would have a much more stable flight characteristics and it's easier to track along a line with all the mass compared to the small more twitchy quad.

As for IF Protek 35 vs Bumblebee, I can only speculate that it may be a "little quieter " , steadier in more windy environment and likely longer flight time if you don't do too many power loop/ more demanding acro moves. Protek 35 is quite heavy too at 360g before GoPro and 190-200g lipo.

If you have 19 mins to kill, Kabafpv just released a video talking about Cinewhoop/ducts.
