Hoyt RX-9 ultra 80 lbs

[1jeds]

I’d have thought with your specs you’d be at 310.
My arrow and DL are same as yours and I’m getting 306 with RX-8 80 lb. Wasn’t the average increase to be 18fps?

Were you using a decent chrono?

It was a Garmin Xero at the bow shop. I'll validate the draw weight at home (the shop was supposed to set at 75#, and it felt about right) and shoot it through my chrono.

Personally, I have the RX8 Ultra, and with the RX9 and my draw length (30.5), I gain about 2 FPS over the RX8. It would be great, at least in my opinion if Hoyt Made their bows more tuneable next year as the speed improvements don't really seem to be there. Especially when I can buy the new Gas X bowstrings and get the same speed improvements out of my RX8.

Update - I verified the draw weight at 75# and changed the letoff from 85% (I incorrectly said the shop set it at 75% in my original post) to 80%. Shot it through my chrono and it is at 299 fps.

My previous Ventum 33 was shooting 483 grain arrows at 279 fps with all other specs the same, so it's shooting faster but likely not the 18fps or whatever was quoted. Regardless, it shoots like a dream and is a nice upgrade for me. Sounds like your RX-8 is shooting darts, and probably wouldn't be worth it for you.
