Vertical takeoff or landing - VTOL - is among the toughest challenges in aeromodelling. This is especially true when you throw ducted fans into the mix. Fortunately, 3D printing is here to help. This three-bearing swivel module (3BSM) model mirrors the design used on the F-35B jet. When coupled with the right electronics and software, you can create ducted van VTOL models of your own!

Compatibility

The 3BSM design fits FMS 70mm EDF units, but should be compatible with other similar fans as well. If your 70mm EDF doesn't fit, Contact Us and we'll design an adapter.

Resources

This design is similar enough to the 90mm 3BSM unit that we didn't create separate documentation. Just follow the build guide and videos for the 90mm unit, and keep in mind the following differences:
 
The 70mm unit uses MD70MH-CAN servos instead of MD89MW-CAN
There are six screws & bearings per ring perimeter rather than eight
