طقم زعانف بديلة لصاروخ كويست المائي - Q7322

These are way stiffer than the flimsy tray foam fins I used before, that thin skin on both sides really does make a difference. My rocket still flies straight after a dozen launches and they barely weigh anything.

Wasn't sure these would hold up after my last set of fins kept folding on landing, but the thin skin on both sides gives them real bite in the air. They're so light I barely notice the extra weight, and three launches in they're still dead straight.

Swapped these onto my rocket after the originals cracked, and the thin skin on both sides really does hold up better than the plain foam ones I had before. They're light enough that the flight height didn't change at all.
