It's good to see you again, Bill! You helped me out with a circuit board issue on my CS3 about 2 years back. You are an awesome presence in the airgun world. I have both the CS3 and now the CS4. I think the CS4 is well worth in price difference. Thanks for what you do.

[@TargetForge]

Glad to help

[@presidentspilot]

You did a MAGNIFICENT JOB with LaDonna, Bill!! Her children were AWED!! God Bless!! My memories of her will continue to SHINE-ON in my heart, until I am again with her, once more!! MY DEEPEST THANKS TO YOU!!

You are quite welcome Sir!

Man it is great to see you on a review again! You have been missed. Keep up the great work. You sure handed Jason his A** and that was well deserved. On the other hand I am glad you will not have any affiliation with his organization.

I appreciate that!

[@o.h.sairsoft9065]

just received my CS4 today after watching all your videos debating this unit so far today I have cleared all the gunk out of the coolant reservoir and ran a dead head test 0-300 bar 23sec. Plus filled (4) 68cu 4500 tanks each 0-4300 20min each totally happy with so far thanks for all your efforts in the reviews of this unit!

[@Swamp-Fox]

Great first look at the GX CS4! Thank you for your candor. I am looking forward to the upcoming CS4 content!

[@TargetForge]

You bet!

[@AverageHouseHusband]

Living in a colder climate I confess to using coolants in my Yong Heng, freezing is much more likely to destroy my compressor than the extra heat with the short run times that are typical.

[@jamesperkins343]

Very intuitive, and informal. I ran the "dead head" test on my CS4 and it ran 0-300 bar in 28 sec. Although, it wouldn't run to 400 bar, it bounced around a little above 300 bar.

[@TargetForge]

Hmmmm...

[@antonio999us]

Hello Bill ... greetings from Peru. It has passed some time since our last chat. Thank you for sharing this video, it was very useful to me. I was planning to buy a CS4 or CS3 to replace my CS2. Also I want to tell you that the CS2 definitely turned out to be an excellent pump. Since I began to use the CS2 following your hints and tips, it works very well for filling up my rifle. I'll be alert to watch your next video before to take a decision. Thank you for your work!!!

[@TiredMachine]

Great stuff Bill good to see You back in shop again. Looking forward to the rest of the series on the CS4 I have a Uragan 2 fill pressure 300 bar capacity 530 cc and my CS3 will not fill this before the duty cycle times out. So I think that I need a new compressor. This one will be on my list of possibles.

[@TargetForge]

Can I ask what your current time for the dead head test is? That unit should have no trouble topping that gun off. Filling from zero? I can understand, but refills when you fall of the reg should be no issue.

[@ctk3873]

Great video, what’s your suggestion if a cs3 won’t start. When you push the start button the pump starts but stops as soon as you release your finger. If you continue to keep your finger on the start button it will still shut off after 1 second. Great video, keep it up!

[@wruehl]

It's likely the controller. I have them on the Target Forge site!

I would have loved to have been a fly on the wall when you traveled to China. This was such a thorough trashing of the Jason and the product, GX/Jason had to either love you or hate you after this video.

Sure, you can say a lot of these mistakes were lack of disciplined marketing, but its still a reflection on the product.

Take a deep breath Sam, you are fine. There are no filters needed with the CS4, the separator is very good.

I'm an old guy that was looking for a home hobby. I bought a pcp rifle. I was going to buy a compressor instead of a hand pump. Now I'm not an engineer. I need simple!. I have listened to your explanation of this compressor. My head is spinning. Now I'm not sure what to do. thanks anyway.

[@jumperstartful]

I've decided to buy a break barrel.

That break barrel will make you a better shooter if you stick with it. The follow through you will master to shoot that gun well will allow you to shoot anything well. Don't give up on it too soon and you'll see what I mean.

So let's see what this is all about, that justifies the price tag!! ...It could be a REAL GREAT BUY!!..Let's Hope that it is!!

For your use case I actually would not recommend it. CS3 might be the better choice.

[@presidentspilot]

I already have the GXCS2, Bill! Why, you might ask?: Easier to provide preventative maintenance, better airflow, and cheaper! (With all the metal enclosures, escape of heated air is substantially hampered in the CS 3 version, along with being harder to access maintenance components, should it be necessary. ('Experience' with such problems, has it's advantages!! .....'K-I-S-S'!! Remember? LOL!!

[@drywallman1986]

I wondered about PC cooling liquid. Not for the look but if it can keep those cool through radiators why not a compressor?

[@TargetForge]

To the best of my knowledge the products marketed as "PC cooling liquid" are nothing more than colored water. Water is one of the best, safest coolants available. The freezing risk is still there, and products like Water Wetter give plain water a little bump in cooling capacity. Thank you for your comment!

[@jeansandmyshirt]

Its efficient because its able to fill larger bottles faster and would be more reliable because of stronger components. Also the water and oil is better for longevity. I'd take low noise faster filling and upgraded motor option.

[@TargetForge]

Thank you for the comment. Not really what efficient means, but i catch your drift. It is a nice machine.

[@kofi61]

Thanks

[@TargetForge]

My pleasure Sir.

[@jaymz8222]

Which model would you reccomend to me - I just want to shoot a couple boxes of ammo and hunt for a few weeks of next hunting season on my property filling up one individual gun. and I use a Seneca Cap Dragon Claw ll mod.

[@TargetForge]

I think the CS3 or the CS4 would be great choices. The CS4 would allow the addition of a bottle in the future if you wanted one.

[@titiki1000]

Bought one & waiting for it to come. Have 2 HY compressors, which I'm very happy with. Need something to move around to the range and matches. This fits the bill and performance. You were spot on with the comments for the chinglish manual and the behavior of the amazon sales man. However, your poignant frustration with him comes across as petty and is somewhat unatractive. So he did not want to hire you. Who cares... Chinese businesses seldom care about optics. If they lose one sale and can still sell 2 after, they do not care as they are still in business. Lol

[@TargetForge]

Good choice!

[@keith4866]

Can you tell me where to get a 90 deg connector for the hose, and how to get air gun parts to Alaska, no one wants to ship here.

[@TargetForge]

Honestly not trying to be a wiseguy, but can't you simply flip the hose whip around so the 90 os on the other end? There are SS 90's rated for 4500 PSI but they are not inexpensive. Do you have a friend in the lower 48 that can receive your order and ship it to you? I know you end up sometimes paying twice the shipping but I have customers in Europe that do this all the time.

[@brucehanson9976]

Is it ok to shutoff my yung Hang air compressor at 4500 psi on a dead head ? I read some were not to do it, That it could heart it ? I have always drained the psi before I shut it off.

[@TargetForge]

Pretty sure that pressure just sits on the output check valve and it's actually designed for that. Many have "invented" care and use directions for the Yong Heng that make no sense to me.

[@brucehanson9976]

OK fine, I trust your opinion. Bruce.@@TargetForge

[@joshuagibson2520]

Yong Heng till I die.

[@perniciousprogressive8333]

Not an engineer, but... I seem to recall testing of various coolant/anti-freeze solutions that showed zero improvement in heat carrying/dissipation capacity of all of the various miracle concoctions. What they do provide is freeze protection, but if you're anything like me, all of my liquid cooled gear is kept in a conditioned space where freezing is never an issue. What that all means is that ya aren't gonna do much better than plain water as a cooling liquid in these systems. Now as to what defines plain water, that's a whole 'nuther room, but the issues worth consideration (imnsho) are pH & mineral/salt content. Pure H2O is actually dielectric by itself, it's the various salts and other chemicals typically found in say, tap water, that make it conductive. Just something to keep 8n mind when you're introducing water into an environment filled with a bunch of electrical components. Those salts/minerals work to buffer pH and keep it from bouncing or drifting as maybe CO2 is absorbed (which will decrease pH making it acidic). Pure H2O has a pH of 7.0, which is neutral on the pH scale. Unfortunately, trying to keep it neutral can be a challenge since things like atmospheric CO2 (especially under pressure) and iron will cause the formation of acids (like carbonic) which will in turn cause the pH to drift into the acidic range. I only mention this as a consideration for flushing systems routinely and replacing w/ pure H2O to keep that pH closer to neutral. Love the channel.

[@TargetForge]

Actually Antifreeze reduces the capacity of water to move heat.

[@gooderspitman8052]

What is the longevity without a strip down? Great insight, think I’ll pull the trigger on this update.

[@TargetForge]

The factory claims that 250 hours should be achievable. I'm nowhere near that so any thing I offer is anecdotal at best. What I do know for certain, they are quiet and don't seem to be pushed right to the edge of failure. I would guess a CS4 filling guns directly would last a pretty long time. Thanks for the comment!

GREAT VIDEO!!! I just ordered the GX CS4 from amazon and have a couple questions. Can I fill a 9 liter cylinder with it? Would replacing the grease in the grease pot with Super Lube be of benefit? What's up with the internal oil/water separater and not needing to use an additional one? Amazon

[@TargetForge]

9l should be fine, especially just topping it off. I would not change the grease.

[@ronaldjones4569]

Thanks What about the oil water separater. Need one????

The separator they include in the design seems to work pretty well. I would advocate for regular purges or venting during a long fill. No oil to separate that I have seen.@@ronaldjones4569

I have watched and liked all your vid's on this compressor. Now can you get parts for rebuild, As I know these always fail..... I have had to rebuild my twin cylinder 4-5 times. High rpm compressors don't like scba bottles, they do fine for 1/2 Ltr and direct fills. I thought about a Tux to run with my current unit, but Tux sent me used parts and 1/2 my quantity of rings, lucky my payment provider covered me when they refused to respond. So I'm seriously looking for a second unit, probably to run in tandom with what I have.(cut run times with more cfm) Thanks. And my vote is;: fire Jason

[@TargetForge]

Not sure I'm following what you wrote. The CS4 is not high rpm, it runs slower and cooler that the cheap Chinese rattle traps. I will be carrying rebuilt and new cylinder kits for the CS4 and CS4-I (Same pump). These fill large volume SCBA tanks with ease, no stress, no drama. Jason is an interesting bird, that much is certain, love your vote!

CS4 looks like grade A Chinesium! I hope my off brand blue compressor stops working some day so I can get a unit sold from Umarex. At least that way I can go after someone if I experience a catastrophic failure. 300 bar is no joke. Unfortunately or probably fortunately, that cheap compressor still works with the only the issue I have is the motor oil gasket not being oil tight. Too bad a Hill is so expensive and it is a UK / Non EU company.

If the price was fifty percent less I would be very interested due to the low noise level while working. In my opinion it seems to be overpriced when compared to the $420 dollar Tuxing TXED011 dual cylinder compressor. I do understand the comparison is apples and oranges.
