زعنفة أيروتيك تشيتا الدقيقة المصبوبة بشكل انسيابي - 11716

Wasn't sure about gluing these on versus using the Fin-Lok mount, but the bond held perfectly through three launches on my 2.6 inch build. High impact polystyrene really does flex instead of cracking on hard landings.

The molded polystyrene is way tougher than the balsa fins I used to break on every landing, and the airfoil shape is already smooth right out of the package. Fit the Fin-Lok mount on my 1.9 inch build with zero sanding needed.

Glued these straight to my 2.6 inch body tube instead of messing with a Fin-Lok mount and they sat flush with barely any fillet needed. The airfoil shape is noticeably cleaner than the flat balsa fins I used to sand by hand.
