since the goal is max speed and not distance, wouldn't it be easily achievable to get an unfletched carbon arrow to very light weights, u can even have no arrow point in theory

How do you think you get MAX distance?

You get max distance with MAX SPEED.

To get max DISTANCE, you need MAX SPEED and correct arrow launch angle.

You can aim dead LEVEL, and still have the same MAX SPEED...just will not hit MAX distance.

MAX DISTANCE comes from MAX speed.

MAX SPEED and distance comes from the arrow design.

So, same answer. Look at FLIGHT arrows, for MAX speed.

No arrow point, will be EXTREMELY LOUSY aerodynamics.

Cuz you are shooting your arrows on planet earth, in an atmosphere, your "theory" would only apply in a vacuum.

Unfletched arrows fly CRAPPY in an atmosphere, cuz the slightest disturbance will cause the Un-Fletched arrow to tumble, to spiral.

If the unfletched arrow starts to spiral, you create shaft drag..unstable shaft drag, and you lose MAX SPEED.

So, one more time,

look to FLIGHT archery arrows, for proper arrow design for MAX SPEED, which creates MAX DISTANCE,

when you get the correct Launch angle.

Since you don't care about MAX distance,

ignore Flight Archery launch angles

and just focus on the HOWS and WHYS for flight arrow design.

Need fletching to create stabilization, for optimum flight, for MAX speed.

Since you don't have PERFECT form, you need the fletching to stabilize the arrow for stable flight, for MAX speed.

Fletching makes the arrow more forgiving. Means slightly SUCKY form, you still get close to MAX speed....when using vanes.

IF you perfect your shooting FORM,

then, the arrows with fletching will get closer to MAX speed.
