Hi
Whats the difference from 7.0 Shaft and 7.2 Shaft
And whats the diamond shape for Brave Sword for.
Thanks

diamond shape is for the racket to reduce the air resistance ad let it cut the air smoothly

i think i don't have a fast enough swing speed to actually tell the difference between my BS11 and my SW35. but yes, that is the reason for the sharp edge shape on Bravesword frames.

Smaller diameter shaft has less air resistance

that's the diameter? i finally got a answer now, i always thought it was some extra mineral or materials added into the shaft

Are you sure that's not just marketing gimmick ?. Drag coefficient for that shape is more than stream lined body (source)

marketing gimmick? but its work for me

it looks more like a slimmer angled cube to me

**cyberangle208** · 10-02-2012, 02:49 AM

Well its more of a streamline with an angle edge... So lets say the coefficient of a angled cube and a streamlined body is being used in designing the Bravesword line of racket... so ((0.8+0.04)/2) = 0.42 drag coefficient. I KNOW THE MATH IS NOT CORRECT but its logically right

So get a BS and with this in mind i bet u can swing the racket faster...

PLACEBO!!!!

so what we need is a racket with a streamline profile,

it would only work in one direction but would be super quick,

also you could profile the shape as below

this would result in the frame trying to expand outwards increasing the tension on the string as you swing

fuuu... u never know... u never know....

Bit of a funny thread this has turned into.

Anyway, the shaft diameter is not just for aerodynamic reasons, but also changes the flex of the racquet so may feel quite different. Classic example would be the difference between an original Cab20 and a Cab21, both have almost identical frame shape sections, but the Cab21 has a much thinner shaft and feels quite whippy but not excessively so.

And on the point of aerodynamic shapes, you are forgetting that in most power stokes (when aerodynamics are most important) the racquet face is not perpendicular to the direction of travel most of the time, until the point of contact with the shuttle. Read up on the features of the Z-Slash and you will understand what I mean.

This is why the old Aerotus racquets actually felt worse or at least no better travelling through the air compared to a standard racquet despite its claims for lower air resistance. Structurally the "wing" shaped section is also quite poor making the aero shape terrible for control, feel and off-centre shots.
