Designed to be light, but not fragile:We spent extra time testing Räsvelg, because we needed to be sure the frame could take abuse. After several iterations with various arm widths, carbon fiber thicknesses, and configurations, we finally arrived at a 5″ version with 5mm replaceable arms and a 3″ version with a 3mm unibody plate.
The result is that Räsvelg 5 weighs in at only 75g
Räsvelg was designed to have skinny, yet thick arms for the best possible gains in aerodynamics. The result is a frame with less surface area, so more of the thrust created by your motors gets turned into forward movement. Additionally, the canopy’s open design creates the least amount of air resistance possible.
Battery strap: solved
We fly hard, and we break battery straps when that flying turns into a certain kind of crashing. Traditionally, replacing a battery strap in the field has always been hugely annoying, with most frames requiring you to weave the strap through small slots.
Räsvelg 5 fixes this with relief in the replaceable arms that allows you to slide your battery strap straight through, no weaving required.
Räsvelg: The giant corpse swallowing eagle.
The name Räsvelg comes from the Old Norse, Hræsvelgr, and a giant that takes the form of an eagle and flaps its wings at the end of the Earth to create wind currents.
It’s also affectionaly known as “corpse swallower,” because it does a bit of that too.
Compatible with the most common hardware.Räsvelg is compatible with the parts you’ll see on most builds. However, Räsvelg requires the following:
- Flight Controller: Any flight controller with a MPU6000 gyro and 30.5mm mounting holes
- Motors: 22XX motors or any motor with standard 16×19 M3 mounting holes
- ESCs: A 4in1 ESC is required in order to gain the benefits of Räsvelg’s aerodynamics
- Camera: Foxeer HS1177, RunCam Swift, RunCam Owl Plus, or other camera whose case is 25x25mm with screw nubs
- VTX: Any VTX with a SMA pigtail (or the SirinFPV flight controller with built-in VTX)
- 5″ props
- 5mm replaceable arms
Räsvelg’s included hardware lets you soft-mount mount your PDB and flight controller. The included o-rings help prevent yaw-twitching for those sensitive gyros and motors with N52 magnets.
