Description
Remake BetaFPV Pavo 20 whoop duct 3d printed.
Why 3d print the duct
The original whoop duct cost $4 but your printed one is even cheaper ;-) also with different colors and to try different materials!
Pavo20 has a molded frame with PA12 material. It is quite heavy. Here is a free version of it.
It is not reverse engineering the original frame but fleshly design.
The original whoop weighed 13.8g.
There are 2 versions
Original frame dimension from BetaFPV website.
Suggested materials:
PETG has a very similar mechanical properties to the orginal PA12 but when it with CF, it loads much better.
You can also try with PLA for prototypes.
You will need 4 m2 screw inserts with diameter 3 or 3.2 mm.
Use heat insert by soldering iron or screw driver heated by a lighter. Press from top until it is the same level as the plastic part.
