Description
The name for these was inspired by 3D printing and how it is a disruptive technology, rapidly advancing past what many people think of tried and true.

I created these jetunit stators with the original intention of pairing them with FJD series 35mm intakes designed by others. The nozzles have a spherical fitting to the stator end because this minimises frontwash and improves turning radius. The stator vanes are variable pitch from high at the centre to low at the tip for efficient operation. I'm working on a jetboat hull here: https://www.thingiverse.com/thing:4051537 which I've built a compatible intake into.
The FJD intakes (with their own nozzles, stators and impellors are here: https://www.rcgroups.com/forums/showthread.php?2826297-FJD-3D-printable-Jet-Drives
you can make up your own mind as to wether you prefer fixed pitch vanes or the ones I've done. My 4BDN design thread is here: https://www.rcgroups.com/forums/showthread.php?3441451-4BDN-FJD-35mm-stator-alternative
The stators are designed to take a 13mmOD x 5mmID x4mm long ceramic bearing and a 10mm outer diameter grease seal, a 5mm stainless steel shaft.
