Best Arrow Setup for Hoyt Carbon RX-10 (2026)
The Hoyt Carbon RX-10 is a 30.5-inch ATA carbon-riser flagship with HBX cams and a 342 IBO. It is fast, light, and unforgiving of a sloppy arrow build. The carbon riser dampens vibration differently than aluminum, which changes how the arrow loads. Here is the setup that actually works on this bow.
Spine, by draw weight
HBX cams hit hard early in the draw cycle. The arrow needs to be slightly stiffer than the static spine chart suggests. Confirm every recommendation in The Forge dynamic spine calculator:
- 60 lb, 28" draw: 340 spine, 100-grain point. Do not drop to 400.
- 65 lb, 29" draw: 300 spine, 100-grain point. This is the sweet spot.
- 70 lb, 29.5-30" draw: 250 spine, 100-125 grain point. Required for long-arrow hunters.
The RX-10's carbon riser transmits less harmonic distortion to the shaft, which is why a stiffer spine reads cleaner here than on a Hoyt RX-7 or RX-8. Skip the 400-spine recommendation you might see on generic charts.
Top arrows for the RX-10
Three shafts pair best with this platform:
- Easton 4mm Axis Long Range Pro: The default. Micro-diameter, .001 straightness, and the 4mm OD matches the RX-10's tight clearance window. Best all-around.
- Black Eagle Vintage: Heavier per inch than Axis, with a more forgiving spine response. Pick this if you want maximum FOC for elk or moose.
- Sirius Apollo: Premium .001 micro-diameter shaft built for long-range hunting. Pricey. Worth it on a $1900 bow.
Skip standard 5mm Axis on the RX-10. The riser geometry favors smaller diameter for cable clearance with a 6" stabilizer setup.
Components
- Inserts: Ethics Archery stainless half-out, 75 grain. Iron Will impact collars if you run fixed-blade broadheads.
- Nocks: Easton 4mm pin nocks. The HBX cam loop drops at a steep angle, and pin nocks survive better than press-fit on this geometry.
- Vanes: AAE Hybrid 1.85" or Bohning X3, three-vane, 2-degree helical. The RX-10 launches hot enough that bigger vanes drag the arrow down past 60 yards.
Tuning the RX-10
The carbon riser flexes under load. That sounds bad. It is not. It means the rest needs to be mounted with the correct torque on every screw or you will chase a bullet hole for hours.
Torque-check every rest, sight, and quiver mount screw before tuning. Hoyt spec is 35-40 in-lb on rest mounts. Then:
- Paper tune at 6 feet. Expect a small high tear, which is normal for HBX cams.
- Bareshaft at 20 yards. The RX-10 shows arrow tune faster than any aluminum-riser bow. Trust what you see.
- Walk-back to 60 yards before touching cam timing. Most RX-10 issues are arrow-side, not bow-side.
Sight tape: what the RX-10 actually shoots
A 70 lb RX-10 at 29.5" with a 450-grain 300-spine Axis chronographs around 290-295 fps. That is the input the sight tape generator in The Forge needs. The IBO speed printed on the limb sticker is useless for a real tape.
RX-10 owners tend to run premium sights. Spot Hogg Fast Eddie XL, Black Gold Ascent Verdict, and CBE Engage HYB Micro all pair well with the carbon riser's lighter axle-weight distribution.
One more thing
The RX-10 deserves a build sheet you can return to. The Forge tracks every component, spine calc, and tune session so you are not rebuilding from memory in 14 months when you swap broadheads.
