Hey All,

I have some questions in regards to the Carbon Express Maxima Red arrows and the spline that I would need.

These are the calculations I arrived at from the chart at this site: http://www.carbonexpressarrows.com/sites/default/files/2013_MAX%20RED.pdf

I currently shoot a Mission Blaze pulling 65 lbs with a 27.5" draw and 26.5" arrows.

The starting weight would be 65 lbs then.

1. Measured Draw Peak Weight = 65
2. High-Energy Cam +8
3. 65% - 80% Let-Off -5
4. Insert & 100 grains Screw-In Point -7
5. Arrow Length 26" to 27.9" +1
6. Finger Release +6 (assuming they mean mechanical release, who would shoot fingers only on a shorter ATA compound?)
7. If the bow's IBO speed rating exceeds 335 FPS +12

TOTAL: 80 lbs

Okay, so 80lbs is the calculated poundage. If you refer to the arrow shaft selection chart on the page below the adjusted draw weight calculation page you see that a 26" arrow @ 80lbs should be 250 spline and a 27" arrow @ 80lbs should be 350 splined.

Since my arrow length is 26.5", do I round up? Round down? Disregard chart entirely? Also, if they do mean "finger release" that would decrease the calculation by 6lbs and the chart would lead to a 250 spline arrow for 26" and 27" arrows.

Just looking for a little help and guidance.

Thanks,
Dave

They do mean finger release....by the way. And arrows have a spine not a spline :wink:

I’ll soon be purchasing a dozen maxima red arrows. I am unsure if I will get the SD smaller diameter shafts or just the standards.

i am wondering what spine I should go for. To make it worse their spine size numbering is backwards. Eg- Their size 250 is a 400 spine.

i shoot a Mathews v3 at 75 pound
Arrow length is 29”
125 broadheads + 20-50grain inserts ( I am undecided on inserts but I’ll first try what comes with the shafts)

I normally shoot 250 spine arrows
The maxima reds only come in 2 sizes. Size 250=400 spine and size 350= 350 spine which apparently cover most situations up to a 90 pound bow.
The maxima red SD has an extra size which is 450=300 spine.
Will the size 350=350 spine be fine for either shaft or should I go with the 450=300spine if I choose the SD’s. It would be handy to save some GPI if the 350s will work. But in saying that 350 spine sounds weak for my setup.

That’s what I was thinking. But like I said, the maxima reds only come in 400 spine or 350 spine and apparently they can be used for anything upto a 90pound bow. And I’m guessing the SDs in their stiffest option in 300 spine would be their safest option and still covers upto 90 pound. Sounds odd compared to other shaft spine charts. I guess I’m hoping someone can verify

Well, I'm telling you they aren't going to work with 90# unless it's a really soft cam. I haven't shot the Maxima reds, I shot the old Maxima hunters. There was a time they were the most consistent spine shaft I could find, but they aren't going to work @ 75# and 29". Their chart might say they will, because they don't make anything heavier. I think they are safe, not going to blow up, but they aren't going to tune correctly.

The V3 pushes a shaft pretty hard. Then add in the fact you are at 75#, added weight upfront, and using a 29" shaft, you need to find something in a 250 spine.

Looks like CX Maxima Red SD's retail around $200/dozen ($16.67 ea) fletched with inserts & nocks...that's not a cheap arrow. If you're set on small diameter (0.204"), Easton 5mm Axis and Black Eagle Rampage have comparable straightness tolerances (±0.003"), are available in ≈0.250" spine, and cost around $11 ea. Victory RIP TKO Gamer and Gold Tip Kinetic Kaos would be other comparable options around $15 ea. If you're willing to entertain standard diameter (0.244-0.246") arrows, that would open up even more options.

I see no reason to push your luck on being underspined in order to use a CX arrow. Competitors offer similar options in appropriate spines at the same or better prices. CX's claims about improved accuracy due to their "multi-spine" technology (whatever that means) are pure marketing hogwash.

thanks for the suggestions.
I am leaning towards a standard diameter shaft. I only considered the small diameter maxima reds sd because they come in a stiffer spine compared to the standard diameter maxima reds.
What do you recommend in standard diameter 250 spine. Preferably not overly heavy gpi

What is the difference between Maxima Red and Maxima Red SD?

The maxima reds only come in 2 sizes. Size 250=400 spine and size 350= 350 spine which apparently cover most situations up to a 90 pound bow. The maxima red SD has an extra size which is 450=300 spine.

What size field tips for Maxima red SD?

Maxima RED SD is the best tuning hunting arrow ever- manages dynamic spine so well it only takes wo spine sizes to cover 40-92 pund bows. Comes with Carbon Expressi Launchpad nocks and Bulldog red nock collars, Half-Out inserts and regular 19/64" 100gr Field or Combo points.

How many grains is a carbon Express Maxima red?

Regular insert (Arrows ID . 244) is 11 grains.

Are Maxima red arrows good?

The Maxima red arrows are, without a doubt, the best shooting arrows. You will need the best bow and arrows for your shooting sessions, and The Carbon Express Maxima are the best you can get. I would recommend giving these arrows a shot and see for yourself how good they are.
