High-performance Fin Can Machining (Holes)
GLR Acme High-Performance Fin Can™ Machining
Weight = 11.8 oz., that's about 15% lighter - and the weight loss is where you need it most - at the rear of the rocket!
TECH TIP: For low drag, fill the holes with lightweight filler or foam! That preserves the laminar flow but keeps the weight off.
