Hubsan H501S Legs for stock propeller guard

Legs that adapt to the stock H501 propeller guards. To be fastened with zip ties to the prop guards

For once, no A/B propeller nonsense: this is the same part for all 4 prop guards!

For those who use the stock Hubsan prop guards : have you ever noticed the small notches below the middle arm of each guard? I don't know what their initial purpose is (does anyone know?) but I thought they would be a perfect base to fit some legs.

With those prop guards + legs, my H501 is back down to 540g,
