1. Core Advantages - Three Boundaries of a Slim Racing Tube
How thin can we go? Wall down to ~1.5 mm on slim OD - each arm drops to a few grams. That's where the agility gain lives.
Why not thinner? Past the limit, the arm droops under motor torque and snaps on the first hard landing. We set the wall at the edge of "still works," not "still flies for a minute."
Crashes happen - that's the design assumption. Slim arms are consumables; we price them as such and use ±45° layup so the arm flexes before it fractures.

5. FAQ
Q: Will a 0.8 mm wall arm droop? On a light 5" motor, tuned layup handles it; bigger motors need 1.5 mm. Tell us your motor weight.
Q: What if I crash? Slim arms are built as replaceables - price and lead time reflect that.
Q: Which OD for my frame? By frame size: 5" → 10–12 mm, 7" → 12–16 mm. Match your clamp.
Q: Can you match my existing boom length? Send the old tube or length; we cut to match.
