$4.87 $6.49 In stock

These rigid foam fins are die-cut from a unique rigid foam material that is super lightweight and has a thin skin on both surfaces for strength. Much more rigid and sturdy than foam meat tray type fins. Each fin is precisely cut to fit into a center ring. After the three fins have been slid into place and the alignment carefully checked, you apply a fillet of low temp hot melt glue to each fin/ring joint. This allows you to get perfect alignment each time. And for the SAFEST fin attachment system ever, the completed fin unit is held onto your PET bottle by the molded rocket nozzle (Q7321). Fins are NOT required to be glued to the surface of the PET bottle.

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.
