Welcome to the Fractal65 Whoop BNF Page!

Due to the small, boutique operation I’m running, I can only keep minimal stock for these kits, and I’m running production on a rolling preorder basis

If you see no stock, please back order to reserve your spot on the next batch, launched monthly

I try to always produce some extras, so you may get lucky and find some units in stock at the beginning of the next month, but your best chance to get one is to backorder

Each batch opens on the first day of the month, closes on the last, and is estimated to deliver by the end of the following month

Thank you for your understanding and whoop on!

  • Are you a whoop racer looking for the sharpest performance without compromising reliability?
  • Or perhaps a freestyle pilot that wants a robust frame with quick maintenance?
  • Maybe you simply want a stronger alternative to those flimsy nylon frames to keep you longer in the air?

If you answer yes to any of those, then the Fractal 65 was designed for you!



— A little backstory —

The lifecycle of this craft started back in 2018 already, right around when brushless 0603 powertrains appeared and started looking like a solid next step in 65mm whoop class

Back then I entered the class with a UR65, and although it flew great compared to any other canopy whoop I’ve tried before, something was still off…

The nylon frame didn’t seem to hold up very well to the added weight and power from the brushless era design.

It needed to improve on 2 main factors; rigidity and weight.

So I went to work and came up with the first revision of the project, based on the CrazybeeF3 board and 0603 spinners.

Basically an UR65 powertrain on a carbon frame with individual ducts and 3D printed parts

And while it was great for my basher use, the weight, at 23g wasn’t quite up to my standard…so the project fell off, waiting for better hardware to support the idea…

For almost 3 years I kept flying the first revision occasionally until Happymodel released the right hardware that would make it all possible this time…

You may think there isn’t much to it, that I’m just pulling it out of my arse, but trust me, there is lots of R&D and testing that went into it; I wouldn’t have released it otherwise.

This frame was designed to the lightest it could, where it could, without compromising strength, where it needed it the most, in true aerospace engineering fashion.

here’s a little snippet of the FEA optimization I performed,
ensuring the stress gets spread out across the whole structure without concentrations



— So what about that frame? —

Remaining true to its original intent, the Fractal65 features:

  • 65mm diagonal, squished X geometry, for 31mm props
  • 1.5mm Carbon Fiber / Individual Nylon ducts hybrid construction
  • Low-profile camera mount, no props in view, no tilt offset
  • Low Center of Gravity, by bringing the AIO closer to the frame/motors
  • Allows mounting with USB pointing up for easy accelerometer calibration
  • No need for a canopy as all electronics are tucked safely between the ducts
  • Maximum rigidity where it matters most; connecting the motors to the FC
  • Easy maintenance, break one duct, replace only the single duct
  • Lightweight, around 19.5g with HM DiamondF4

As always, this is a project that I designed for myself first, that I put together in a product to share with any pilot that would like to experience the same level of requirements!

Designed with love, by a pilot, for pilots.




— What do you get? —

As a BNF version you will get a ready-to-fly quad assembled by yours truly

It will come with a Happymodel Diamond F4 Frsky only, Runcam Nano 3 camera and EX0802 motors of your choice. JST-PH pigtail as opposed to pictured.

It will be tuned to the latest, bleeding edge firmware, including a Project Mockingbird based Betaflight tune with RPM filtering and actual rates, as well as BlueJay ESC firmware

I sometimes help out assembling pre-builts with Armattan, so if you’ve ever seen the standard to which these are built, or seen my soldering jobs before you know it will be top notch.



  • 1x Fractal 65 Frame Kit
  • 1x Happymodel Diamond F4 Frsky
  • 4x EX0802 motors
  • 1x Runcam Nano 3
  • 2x Gemfan prop sets (one assembled, one spare)




-Due to continually ongoing development the actual product may differ from pictures.
