28mm (25x25 holes) motor mount on 22mm Ritewing mount

thingiverse

This is a fantastic modification made by boost_9jr, featuring a 22mm 16x19 motor holes that are filled and replaced with a 25x25 bolt pattern to accommodate a 28mm motor. To make this work, you need to flip the mount because the 28mm mount won't fit inside the part of the 22mm mount that's glued into the wing on Ritewing designs. I've only included the 1mm version from boost_9jr's design since I needed it myself. **Note:** I haven't flown this mount yet, and the pics shown were my mock-up printed in PLA.
