Brushless 0603 S3 Pattycake FPV Hovercraft / Tiny Whoov

thingiverse

I've upgraded my 0603 brushless motor mounts from the original design to support 0603 motors (mine uses motors salvaged from a URUAV UR65). The motor mounts now feature larger holes to accommodate wire bundles and VTX/camera wires, which I needed to access for my setup. To secure the motor/camera mount piece, I applied super glue to the base as the tension of the original design was compromised when enlarging the holes. I've used rubber standoff grommets for a whoop flight controller to achieve a tighter fit for my Crazybee F3 flight controller. Due to space constraints, I only managed to use two grommets instead of four, but this provides a secure and soft-mounted fit. During my maiden hover attempt, the drone spun wildly due to an issue with motor mapping. To resolve this, I swapped the front and rear motors on both sides, then checked each motor individually in Betaflight while connected to a battery. By feeling which side of the motor was pushing air, I identified the culprit – one rear motor was sending air in the wrong direction – and corrected it in BLHeli. With the motor mapping issue resolved, the drone hovered and steered fine but had excessive power. To address this, I set a 50% throttle limit on my Taranis X-Lite's Output screen and swapped the rudder and aileron channels using the Mixer screen. This allowed me to dedicate the left stick to throttle control and the right stick to steering, achieving a balance of speed and maneuverability that prevents the drone from jumping off the tile or flipping over.
