This is a 3D printed fin made of TPU filament. It weighs about 11-13 grams depending on infill (not including zip ties).
It is printed as 2 pieces that need to be assembled and secured to the top plate using zip ties (not included).
The purpose of the fin is to allow 2 propellers to stay out of short to medium grass for "turtle mode" and to better protect your vtx and receiver antennas.
Given these are made to order, please allow extra time for shipping and delivery.
