Closer Look at the Kuda 85X

The Kuda 85X is a lot smaller than a 2.5″ whoop like the Pavo25.

The motors are GL1202 8700KV, suitable for 2S or 3S LiPo. I will be testing it with 3S which would give you a lot more power than 2S. Motor shaft is 1.5mm so make sure to get props with 1.5mm holes.

It’s designed to carry an HD camera, and the power cables are already soldered to the FC. Cables for the naked GOPRO (3-pin), and the Runcam Thumb (2-pin).

The VTX is locked to comply with regulations, power is limited to 25mW and certain channels are not available. However you could unlock it by simply holding down the button on the VTX for 10 seconds, all 3 LEDs will light up for a brief second to indicate it’s been unlocked.

Also it’s relatively safer to fly near properties and people as it’s less powerful. However because of that it’s not great flying in the wind, it will get pushed around.

Geelang Kuda 85x Pusher Whoop Bottom I flew with the Insta360 GO 2 camera and it performed really well. I think an HD camera under 25g is a perfect fit (like the GO 2 or the Runcam Thumb Pro). Extra weight will have a big impact on flight performance.

How to Setup

The FC came with Betaflight 4.3.0 firmware (Apr 25 2022 release), the board target is GEPC/GEELANGF411. Here’s the original CLI dump.

Here’s my Betaflight config for first flight:

  • setup switches for arm/angle mode/beeper/flip over after crash
  • rearrange OSD
  • bind ELRS receiver (connect power 3 times to enter bind mode)
  • Enable Airmode in Configuration => Features (not sure why they didn’t do that in the first place)

My rate (copy and enter in CLI):

set rates_type = BETAFLIGHT set quickrates_rc_expo = OFF set roll_rc_rate = 80 set pitch_rc_rate = 80 set yaw_rc_rate = 120 set roll_expo = 8 set pitch_expo = 10 set yaw_expo = 20 set roll_srate = 65 set pitch_srate = 65 set yaw_srate = 50 save

The manual that comes with the quad, basically just the wiring diagram for the FC.

Flight Performance

The Geelang Kuda 85X whoop doesn’t have a ton of power and speed, but that’s not what it’s designed for clearly. It’s very quiet and nimble, in my opinion is great for beginners. It’s light weight and the frame is quite flexible so it can take some crashes, perfect for a park cruiser or for someone to learn how to fly a quad.

A 3S 450mAh gives me around 3:30 flight time.

It has enough power to carry a small light weight action camera like the Insta360 Go 2 and Runcam Thumb (Pro). However it gets pushed around by the wind, so it’s not as stable as the bigger counter parts such as the Flex25 and Pavo25 for smooth cinematic videos outdoor. It performs much better indoor in that regard.

Some fight footage here:

Even if you don’t carry an HD camera, it’s a fun little drone to practice your acro/freestyle skills in a small park. Flight performance by no mean is perfect, there are some propwash and it wobbles a bit when flighting the wind. But it’s safer and less intimidating to fly close to people than a powerful 5″ drone.

My main complaint would be the FPV camera, it’s really hard to look at, maybe I am just spoiled by DJI :)

And it’s $160… I wish it was cheaper, with around $40-60 more you can get a more powerful 4S whoop like the Pavo25, Venom Hexacopter and the Flex25 which are more suited for outdoor flying and can carry a heavier payload too (though they are not as light weight and stealthy). But if you want a  cheap sub-250 whoop that is more quiet, it’s not bad at all.

Hola Oscar, hice una actualización de fireware y al final no me funcionó. Volví a la versión de julio 22, 4.3.1 betaflight. Volque de nuevo la configuración que me enviaron de China en Cli… consigo despegar y cuando acelero, el drone empieza ha moverse de una manera descontrolada y no se levanta del suelo. He comprobado giro de motores, he cambiado las helices y esta todo correcto. Todo esto lo hice porque se calentaban los motores y al final no consigo sacarlo adelante. Que puede ser?????. Muchas gracias de antemano. Un cordial saludo.

Hi Oscar. Great review as always. Quick question. Does this quad need one of those L-Type micro USB Adapter to connect to the computer?

Oscar 17th July 2023 - 12:54 pm

No adapter wasn’t needed.

Eric 5th August 2022 - 8:14 am

Thanks for the review!

“A 4S 450mAh gives me around 3:30 flight time.”

I guess you meant 3S ?

Oscar 5th August 2022 - 12:27 pm

Yea, I meant 3S. Thank you .

Flight Performance Section:
Is ‘4s’ in “A 4S 450mAh gives me around 3:30 flight time”, a typo?

Oscar 5th August 2022 - 12:25 pm

Yes, it should be 3S! thank you for pointing that out!

Chamol 30th July 2022 - 8:39 am

Hi Oscar, you finish your article by some kind of cliffhanger 😉. What would be your recommandation for a more powerful 4S whoop? Thx for, as always, your very instructive article.
