I am using the whoop at Full Send FPV’s races every week. Lightweight, less than 19.5g with HM DiamondF4Īs 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!ĭesigned with love, by a pilot, for pilots.īut don’t take my word for it, here’s what Team Pilot Glenn “Bellaciao” has to say about it:.Easy maintenance, break one duct, replace only the single duct.Maximum rigidity where it matters most connecting the motors to the FC.No need for a canopy as all electronics are tucked safely between the ducts.Allows mounting with USB pointing up for easy accelerometer calibration.Low Center of Gravity, by bringing the AIO closer to the frame/motors.Low-profile camera mount, no props in view, no tilt offset.1.5mm Carbon Fiber / Individual Nylon ducts hybrid construction.65mm diagonal, squished X geometry, for 31mm props.Remaining true to its original intent, the Fractal65 features: Here’s a little snippet of the FEA optimization I performed,Įnsuring the stress gets spread out across the whole structure without concentrations 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. 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. So I went to work and came up with the first revision of the project, based on the CrazybeeF3 board and 0603 spinners.īasically an UR65 powertrain on a carbon frame with individual ducts and 3D printed partsĪnd 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…įor almost 3 years I kept flying the first revision occasionally until Happymodel released the right hardware that would make it all possible this time… It needed to improve on 2 main factors rigidity and weight. The nylon frame didn’t seem to hold up very well to the added weight and power from the brushless era design.
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 classīack 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… If you answer yes to any of those, then the Fractal 65 was designed for you! Maybe you simply want a stronger alternative to those flimsy nylon frames to keep you longer in the air?.Or perhaps a freestyle pilot that wants a robust frame with quick maintenance?.Are you a whoop racer looking for the sharpest performance without compromising reliability?.
