Terraplane fpv duct spacers

thingiverse

Duct spaces for the shendrone terraplane. Print 20% TPU, glue in place between the ducts with E6000. 2 sizes included, 13.7mm and 14.7mm measured at the center of the hourglass. Open end point towards the middle of the quad and provides a space for the ends of a crossfire antenna to sit in. This has completely cured any duct vibrations I had previously., and they have held up nicely, (never had to mess with that again after installing these). Note: The reason for the 2 sizes is that my build required a 13.7 on one side and a 14.7 on the other. May be just build tolerances or alignment error on my part, but I included both sizes just to make sure.. whatever works and allows the props to be centered on either side. Glued in with e6000. If a duct breaks, you will have to lift both side ducts as as a unit to replace one, but e6000 is flexible and easy to break the bond and replace a duct. Downside is that it takes overnight for the glue to setup to full strength, so this will not be the best i think for field repairs.
