Aurora 90 V1 outer strut

I built up an Aurora 90 a while back, knowing the struts could be an issue. Even after adding 1mm thick spacers underneath the motors, props still managed to strike them in a hard enough tumble. Eachine released a V1.1 which added additional clearance but required new set of ducts and struts that were still installed inside the new prop guard. I decided to model a one that mounts outside to get it totally out of the way.
