DIY Wing incidence meter

Here is my simple home made wing incidence meter. Used to determine the correct mounting angle for wings.


There is much debate about the correct angle of incidence required for efficient flight but a good starting point is to have the horizontal stabiliser and wing both at zero angle, then adjustments can be made after flight tests.

Eachine VR D2 FPV goggles

Banggood sent these goggles to me for review. I needed to add 2 x plus 4 close-up glasses before I could focus on the screen. I really like the diversity receiver with antennas supplies. One clover leaf and one patch antenna. And I love the built in DVR.
