這些硬質泡棉鰭片是由獨特的硬質泡棉材料模切而成,該材料超輕且兩面都有薄皮以增加強度。比泡棉肉盤類型的鰭片更堅硬耐用。每個鰭片都經過精密切割,以適合中心環。將三個鰭片滑入到位並仔細檢查對齊後,您在每個鰭片/環接合處塗上一層低溫熱熔膠條。這樣每次都能獲得完美的對齊。而且,為了實現最安全的鰭片固定系統,完成的鰭片單元通過成型的火箭噴嘴(Q7321)固定在您的PET瓶上。鰭片無需黏貼到PET瓶的表面。

Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas ★★★★★

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.

Natalie ★★★★★

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.

Aurora ★★★★★

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.
