A 5S powered, 2306 2750kV Räsvelg Stretch, the preferred ride of the devil himself.

Technical details

Built specifically with the goal of setting a world speed record, this machine is designed to be as aerodynamic as possible and still have 4 motors and a camera. At 295g dry and 513g all up with a 5S 1300mAh battery, it's not exactly light, but with nearly 2kg of thrust from each corner, it should chooch like none other. A 1000uF 35V capacitor is nestled into the canopy behind the camera to absorb voltage spikes that occur due to the powerful active braking on the RS2306 motors. The 30A Cicada was chosen for its high voltage support and DSHOT support, though its 30A rating will certainly be exceeded at wide open throttle, and as such the craft can't maintain prolonged full-throttle flight.

Craftsmanship

The frame was sanded and painted, and custom aluminum and white nylon hardware was used to have a white/red/black color scheme theme throughout to match the EMAX RS2306 white body red booties. Braided mesh from MRM was used to keep motor wires looking tidy, and to cover up the splicing that had to be done to make the motor wires reach the 4in1 ESC. White zipties and clear heatshrink were used to secure the RX antennas to the front arms so as to not disrupt the white edges of the arm. The XT60 pigtail wires were wrapped through the bottom plate and ziptied individually to make certain that no force would be exerted on the solder joints in the event of a battery ejection.

Thanks

Andrew Sliceoff from The Drive for getting this project off the ground!

Hunter (huntro) for his cutting-edge design work (literally, this thing is sharp) on the Räsvelg and Räsvelg Stretch.

Jake (Jstoltz) for teaching me the paint pen and thin CA painting method used on the edges of the CF.

Brian (AcroFPV) for sending me the red M3 locknuts that really bring the build together; it'd fall apart without them.

Quang (prophetic) for insight on running a 1000uF capacitor to keep the Cicada 30A alive with these motors.

Phoenix 3D Solutions for their amazing 3D printing work.

EMAX USA for providing the insanely beautiful RS2306 motors.

SirinFPV for providing the magical flight controller/VTX/OSD/logger.

FrSky RC for providing the ultra-tiny XM+ receiver.

APC Prop for providing the assortment of high-speed 5" props.

Indestructible Quads for the only battery strap I could find that fits around the 5S pack.
