So much good info, thanks Ventilator.

 

Might as well add the Gen-8 and Gen-9 cams to this thread. These cams are bow specific, both in ATA and Power Stroke. You want the string in the groove along the straight section of the cam while cocked. These were the best pics I could find on this site right now.

Gen-9

Would that apply to all Scorpyd cams or just Gen 8 & 9?

Here is the main differences in the Gen-4 and Gen-5 cams.
There are also slight cam lobe profile changes in the Gen-4 cams. I will add pics of Gen-4a, Gen-4b, and Gen-4c cam lobes.

Stacked the pics so they both fit in one frame. That way you don't have to scroll back and forth to see the differences. Look to the immediate LEFT of the numbers for comparison. You may have to click and expand.
Right side cams.
1. Cam profile, string groove.
2. Cam lobe reinforced, full thickness, radiused corners, chamfered edges.
3. Spoke, material added.
4. Less material removed, so that little crescent is gone. See pics of bottoms of cams.
5. Large chamfer added to the inside perimeter of the cam.

Bottoms of Gen-4c, and Gen-5 cams. Left side cams.

Thanks for the reply Ventilator! I must have missed the Orion 150 under gen three cams. The eBay listing looked like gen 5 cams to me from your pictures. It had black limbs and camo stock, they listed it as 150lb. The other one with camo limbs showed ORION 150# on the inside of a limb. I was also looking for Orion Extreme, since that what's what the seller posted.

When I clicked on your screen name the pop that appeared said you are not allowed access, or something like that. I guessed you barred all private messages.

Don't click on it, point the cursor at it and a box will pop up.

 

I don't know why you aren't allowed to start a conversation with Vent, but there have been sets of limbs for sale, even on these forums. So it is not impossible for someone to change original configuration. My vent 175 extreme came from Jerry aka service center, limbs are 175 and cams are gen 7. So authorized service anomalies do exist.

 

Yes, there are anomalies as stated in Post #3.

"There may also be some anomalies out there from warranty work where newer cams were substituted after that model was no longer in production. Also at the beginning or the end of some model year production runs.

At one time, you could send in your RDT 80, 100, 125, and have it upgraded to the newer cams like a Telson. so, some of those will have Gen 2 or Gen 3 cams on them. I remember a few of them doing that on this forum."

 

I did not see any Orion 150lb listed. Was this an oversight? Reason I ask, is there are two listed on ebay; one as Orion 150 and the other as Orion Extreme, with 150lb in specs. First looks gen 3 cam, 2nd, gen 5 cams. It's also likely the listers have them listed wrong.

 

In Post #1, under Gen-3 cams it has 2014 Orion 100, 125 and 150.

- Gen 3:
2012-14 Ventilator 80, 100, 125, 150
2012-13 Telson 90, 110, 130
2013-14 Velocity 100, 125, 150, 165
2014 VTEC 100, 125, 150, 165
2014 Orion 100, 125, 150
2015-16 Orion Extreme 110, 135,160 (ACUdraw)
2015-16 VTEC Extreme ACUdraw 110, 135, 160 (optional Orion stock/rail required)


Orion Extremes used Gen-4 cams on 2015 and 2016. The Gen-5 cams were not used before 2017. They came on the 2017 Deathstalker 380, and on the Aculeus 450. There were also 2017 Orion Extremes that would have had the Gen-5 cams. They would also have black limbs like the 2016. Gen-4 and Gen-5 cams look almost identical to some. There are structual differences if you look closely at pics below. The Gen-5 has a bit more material in the spokes and cam lobe web.

- Gen 4:
2015-16 Ventilator Extreme 110, 135, 160, 175
2015-16 Orion Extreme 110, 135,160, 175
2015 Orion Extreme ACUdraw (first run only) 110, 135, 160
2015-16 VTEC 110, 135, 160, 175

- Gen 5:
2017 Deathstalker "380", 100, 115, 130
2017 Orion Extreme 110, 135, 160, 175 (Both ACUdraw and non-ACUdraw)
2017 Aculeus "450" 110 , 135, 160, 175 (both ACUdraw and non-ACUdraw)

I tried to send a message, it appears I am not allowed
One of the eBay listings had a picture of the back side of the limb that said: ORION 150# READ OWNERS MANUAL BEFORE USING
The other, listed as Scorpyd Orion Extreme, had 150lb listed as draw weight in the "Item Specifics" section of the description. If had a camo stock and black limbs. I have no idea if they came this way or had stock or limbs swapped?

Yes, the Orion Extreme came with camo stocks and black limbs, starting in 2016 through 2017. The 2015 models still had camo limbs with the camo stocks. There was never a catalogued Orion Extreme 150. There was a 160 from 2015 through 2017. Both as ACUdraw and non-ACUdraw models.

So a bow released as a proto, to some fanboys, is the greatest thing since mashed potatoes. No disrespect to any of the aforementioned, as they all hold my respect, but up to 80 yards, I will put up my 2 old school Scorpyds against the barrelled bows. With the the arrows I use, the tried and true platform shoots as well or better than all the pics of the already legendary X1, yet it is yet to be in the hands of the average real world shooter such as myself. 8 gens of cams, also do not trip my trigger, as truth be told, my Velocity with the gen3 shoots, better than anyone we have at the range, as we are all just average "Joe's" who hunt, and shoot for fun. Ok wouldn't pretend to be a bmiller, but at our range, sub 1.5" at 80 yds gets the oohs and ahhs, and I don't need the barrel to do it.

 

SEW, BMiller, and the other "testers" have shown ENTIRELY too much excitement and enthusiasm for the X1 as being the "ultimate crossbow"! LOL!

 

I spoke with Rex a couple weeks ago about the LT. He told me about the AR stock option but I forgot to ask about what cam the LT had. He did say it was more accurate and less finicky because the new cam design reduces the string angle. That made good sense to me.
I've called and emailed Wyverns on several occasions and the answering machine says the same thing "Due to our busy season we can't take your call right now." That was in winter and 2 weeks ago. So, I sent emails...no answer. Just say'n
I'll buy from Rex if I get the LT. I'm kind of leaning that direction especially since the X1 date is floating around at this time.
Thx
Matt

I have a similar decision to make.....
If both the Tremor and SWAT X1 started shipping today, I would very likely go with the X1.
However, I'm betting the latest X1 ship-date of August 1st is pushed back again to at least Sept. 1st....would be awesome if they truly started shipping first week of August, but my gut is not optimistic about that.

 

I'm pretty sure the AR stock is a $250 option but the LT has a newer cam than the 380 or 420.

 

Cleandate05100,
Wow...I see what you mean...the picture on Scorpyd's website of the new Deathstalker LT looks EXACTLY like the Tremor! Even has the aluminum rail and identical Tremor stock....
I thought the primary difference between the standard Deathstalker 380 and the new LT version was an adjustable, military/AR-15 type buttstock....didn't know it also had the Tremor cams?
On Wyverns website, in the detailed specs of the LT it makes no mention of the Tremor cams....and yet, there is that same photo!
I wonder if the picture attached to the Deathstalker LT description is actually a photo of the Tremor?
Haven't heard any mention of the Tremor cams on the Deathstalker LT?

Wyvern can't sell the DS LT with the AR stock option; that option is only available from Scorpyd unfortunately.

 

I am referring to the pics posted of deathstalker LT and tremor and the cams look identical.
I must have been thinking gen 8 when i wrote about let off and put 80%. I believe it was understood my intention was the same cam on both bows.

 

What cam is on the new Deathstaker LT?

 

Looks like the %80 let off cams off tremor

 

With the arrival of the Tremor and the new let-off cam, it appears we officially have the Gen 8 cam...

 

I would like to see a thread explaining Let-off cams.
What let off is
Which cams are let-off cams (I assume 1-7 gen are not, but they say never assume)
Is it the design of the cable cam or string cam or both?
How much let-off (percent) the cam gives.
Pros?
Cons?
What model Scorpyds have let-off cams

 

TP, I believe the problem is with the riser. The original 380 riser is not built to withstand the force provided by the 420 limbs or shorter strings and cables.

Gordon Glass (PolyOne) are solid limbs. Barnsdale are laminates.

 

Gordon or Barnsdale limbs?

 

No clue, wouldn’t know how to tell. I don’t recall seeing anything even if I got any paperwork with them.

I remember reading something somewhere about thicker limb tips on the faster models up from the DS 380. My replacement tips measure about .470” thick and that was the spec for the heavier limbs I believe.

My DS380 ATA is 17 1/2”, the DS 420 is 16 1/2”.

My string length is 43 3/8” and the cables are 17 1/4”. I would think the DS 420 is a combination of those two being shorter to maintain proper cam timing.

I’m sure there’s a formula to determine the string and cable lengths to get to just a 17” ATA but I have no idea what that is.

 

I would think so

 

I had a limb shear on my DS380 and sent the limbs with cams in to Rex, and I got back a set of Gen 7 cams (2019 Nemesis 480) and what appeared to be considerably thicker limb tips.

Using the factory Rogue string and cables, I set it to the DS380 specs.

I would assume I could set this up a bit hot if I wanted without damaging anything - correct?

Those gen 7 cams are also on my 420. Same limbs as 380 someone said in here. I read they increase carbon in frame or something for the 420. You know all this though. Lol I learn from you.

 

Yes, I agree, Ventilator has been a very big help and I appreciate him sharing his knowledge. We are fortunate to have him on this forum.

 

Vent,.....For the benefit of those of us who really appreciate your Scorpyd expertise & knowledge, Thanks Much!! There are very few people who I’d consider a Scorpyd Expert. Certainly Jim, Rex & Dorge come to mind but you are right there with them as well!

 

Yes Gen 7

 

Oops. Didn't post a pic..

 

I know this is an old post but this is my new Aculeus. Gen 7 cams...correct?

 

I edited that second sentence above 4a, it should have been above 4c as follows.


Here is a pic of Gen 4a cam lobe.

Gen 4b cam lobe.

Here is a pic of a Gen 4c cam lobe. Also note the beefed up web behind the lobe profile.

Here is a Gen 3 cam lobe on the left compared to the Gen 4a cam lobe on the right, and why they used it on the ACUdraw Extremes. Limited to the Orion 160 Extreme until Gen 4c.
Gen 3. Gen 4a.

 

First off, I don't owe you anything. Where the hell do you get off demanding anything from me? I'm only answering this for the rest of the membership.

If you were paying attention, they were trying to make a cam for the Orion 175 Extreme work well the ACUdraw. Gen 4a was fine in the Non-ACUdraw bows, as was Gen 4b. Gen 4c was what they felt they needed for the Orion 175 Extreme with the ACUdraw.

The title says "Scorpyd Production Cams". If they were mentioned by me in my thread, then that means they were all 3 used in production. And yes I know exactly what the differences are, but no sense in confusing anyone since they all use the same exact string and cables.


Here is a pic of Gen 4a cam lobe.

Gen 4b cam lobe.

Here is a pic of a Gen 4c cam lobe. Also note the beefed up web behind the lobe profile.

If you'll notice Gen 5, 6, & 7 all have the same cam lobe profile runout as the Gen 4c. Not a coincidence! All have been ACUdraw friendly.

If you weren't so damn combative in my threads, I might be willing to share more. BUT!!!!!


I could post a pic of a Gen 4b later, if you can get your #1 Sycophant to go away.

This is why I rarely post any new threads, because sure as the world, someone will come and ruin it for the rest. They don't have any substance to add, just a whole lot of drama and BS.

 

Where the hell do you get off demanding anything from me?

I just asked a question that you know the answer to .
No demand , the ball was in your court !!!!
We need to put our differences aside for the better of the forum .
