My two cents, I had mine set for 52# at 29" draw, stooting 436g arrows I chronoed 222fps, real slow! So I went to 372g arrows and chronoed 232fps.
Kinda pathetic, but it is smooth to draw, so? Everything I've read should have given me 242fps+-. Can timing be that big a deal, string, whatever?
I see other brands in my price range shoot 270+, I let them shoot thru my chrony F1, most have less draw lenght but hi'er weight 60-70#. So if you'all have more help PLEASE, thankyou.
Two things I see that jump right out. The first is the tube peep. The second is the location of the string silencers.
Tube peeps are notorious for robbing a bow of up to 10fps. The average is usually about 7-8 fps.
Move the string silencers as close to the cams as is possible. The closer anything like this is to the center of the string the more it affects the speed of the bow.
No doubt on the tube peep, I still would have thought like you that you would have been more like 240 or so. Post up a picture of the cam.
Went back to range and verified 232fps speed with two different arrows.
CarbonSuppreme lite 250 w4"/feathers ,29" both, Goldtip Expedition Hunters 5575 w2"/vanes. All six were within 372g +-2. Using 100g tips.
29"draw and 52# draw weight. shooting thru WiskerBiscut using mechcanical release. Cobra and TruBall. Local pro at range said same thing about tube peep.
Still, it is VERY SMOOTH & QUIETE, and I can consistantly place 3 arrows into the 4"bull at 20yds! My intention is to go after local, Orlando,Fl., wild hogs!
pic's show stop at 5 1/2 using F-7 module position one on M-PRO cam
PS string silencers were factory installed. And I've added a sling onto stablizer

I have an 08 Cheetah set at 62lbs @ 28" draw, shooting maxima weight forward 26.25" long through a whisker bisquet[@ 8.0 grains per inch], and 85 grain heads. My cheetah came set up with the double helix string, on which I have string leeches,d-loop and a peep. It has always chronographed at 268-271 fps. I hope this helps! Good huntin this year!
That cam position looks reasonable.
08 Cheetah... 29" draw, 70lb Draw, Rubber Peep, Kisser Button, Cat Wiskers (seems better that factory leach), D-Loop, Carbon Express 6075 and 100gr tips, Wisker Bisket... 241 FPS

hello i bought my wife a 08 cheeta she is pulling 42 lbs at 25in with a whisker biscute and has a tube peep and d loop and shooting goldtip ultera lights and 85 grain tip and her bow chronoed 215 i think that is damn good so if you want a fast bow get a slyer thats what i shoot its pumping out 230 at 28in and67 lbs
Are you talking about the '08 slayer, cuz a friend of mine has a 28" draw and pulls 62lbs. and is consistantly getting 278-281 out of it...
Maybe he wanted to say 330. :P
