Support 28mm to 30mm Outside-Diameter motors on front tilt nacelles #2

The current design is for the DYS BE1806, which is ancient and out-of-stock almost everywhere. The tilt mounts should be redesigned for any generic 22xx sized motor. This will incur a slight change to the vehicle OML, requiring the nacelles to become a bit fatter.

Nacelles needs much more substantial support as well. Perhaps even so far as adding a bearing/bushing?

Solved by ede11e9. Any regular 2207 or 2306 motor should fit, given the absolute maximum outside diameter of the bell is less than 30mm. Several T-Motor options such as the Velox and Pacer 2306 and 2207 series fit this just fine, but as these are not as tall as the original BE1806 motor, spacers are needed to elevate the motor to bring the prop arc away from scraping on the front of the nacelle. The spacers also help in using the screws that come with the motor, which are longer and need about 5mm to 6mm of space, which is aided by 3mm spacers.

Note that this was the more critical issue that was blocking most people from being able to build the MiniHawk-VTOL. I hope the new nacelle pockets will be sufficient for the time being, but another nacelle redesign is in order given some recent issues with servo torque strain due to the current linkage torque load paradigm.
