As a beginner in FPV and coming from a mini FPV quad H107D to this 250. While still getting use to this larger size quad, I have had a few gentle crashes where the quad ended up upside down with its antenna pressed against the ground.
The flexible antenna shaft seems to take this very well. But my main concern is the energy from the impact on the solid SMA connection connected to the receiver.
Therefore, this is what I came up with. A guard to give some protection to the antenna from upside down landings / crashes, which should prevent impact from crashes to be transferred directly to the receiver via the SMA connection.
