Should you buy a GX CS4-3-2 compressor? Performance testing AND More! Yong Heng Hot Rod Shop

This is actually a follow up to last weeks video where we looked at getting a CS4, and performing a Dead Head test on it. Today's video digs into the actual performance of the CS4 and I think the results are astonishing. If you're looking for a compressor to feed your PCP obsession, you've come to the right place!

CO2 air gunner for years. Since my dad bought me a Crosman Mark 1 when I was 10 because BB guns were too dangerous. I'm 65 now. (still have that pistol and shoot it regularly, along with some other crosman's and some hot rodded Chinese rifles.) And just now getting serious about a PCP. I have no desire to spend all that money on a "finite vessel of air". In reality, the main reason I have not jumped on the PCP bandwagon yet. I have been following your videos for a good while now on the CS2 and 3, and of course the original Hot Rod. Pretty impressive pieces of machinery. Especially being able to run one from a running vehicle. Really liked the plug in set up you did on the truck many videos ago. This CS4 is amazing. I was shocked to see you ran it over 3 hours non stop, and blown away that the manufacturer says it can go 5 hours. I had not read any literature on this model. While it is not what I need, I am encouraged to see the manufacturer is investing the engineering and development time to continue to improve their product line. Thanks for cranking out these videos. I have shared many with my friends. They are a real treasure trove.

THANK YOU!

[@caleb_7777]

Hello from Big Lake. Alaska. I would definitely be interested in a plug and play hour meter setup. Thanks for what you do here. Excellent info and advice.

[@TargetForge]

Design work is completed. Should roll out shortly!

[@WiscAirGunners]

Nice visualization of the capability of the unit.

[@TargetForge]

Thank you Sir!

[@abirch77]

I really appreciate you, your practical (air gunning) engineering expertise and content! TY!!! BTW, I'd take that plug and play kit!

[@TargetForge]

Thank you!

I just got the CS4 and did a Dead Head test. It took 24 seconds from 0 to 300 Bar. I really do not care for the instructions given with the unit. They could have been bullet pointed in sequence and better English. I came to the part where you add the water and it said to fill the tank and start the pump. You then would get an immediate drop in fluid level and to keep adding water until it runs out of the water return hole. So I added the water to about 3/4" from the top and started the water pump and nothing happened with the water level. I waited a few minutes and still nothing. The water was a little discolored from whatever was in there before. I finally had the courage to start the dead head test. It went fine. I then proceeded to fill my 2L tank and it took about 45 minutes. Overall I was very happy it was working well but I will now check into what it takes to flush the water tank. Since I am a beginner I find the lack of clear, thorough, practical instructions for all things PCP wanting. I will be documenting everything I learn from this and maybe take a shot at doing a video from the perspective of a beginner. I think it's easy for experienced folks to overlook some steps because you think your audience should already know those simple things. Anyway, thanks for your videos they do help.

[@seanford1730]

Great video. What water/ oil separator are you using with this combination if any? Great content. Please keep it coming!

[@sdzeltwanger]

Thanks Bill!

[@TargetForge]

Thank you!

[@richardniz]

I use a stick on vibration hour meter on mine and it works great since it also has a shut off function so it doesn't register time when I have it in the car driving to a shooting range.

[@TargetForge]

I have tested many and not found even one that recorded accurately. Most are intended for very different frequency ranges and energy levels. Nice to hear you may have found one. I really like the dependability of my new stick on solution.

[@stedyone1090]

Love my CS4😅❤

[@Edsoutdoors]

Thank you again bill for the info..

[@TargetForge]

Any time!

[@Edsoutdoors]

Do you know if they have a 120volt unit?

[@TargetForge]

The AC adapter (covered in this video: kzbin.info/www/bejne/gaCwqYGEacqWnLs) comes with the unit and can run on 120VAC or 220VAC via a selection switch.

[@fredA1234]

Thanks for a great video. Very helpful. Curious question I’m being told to always use a filter to fill the guns and or the tank and I seen a bunch of them I’m a auto spray painter.would my water and oil filtering system work for this also?? Thanks again

[@TargetForge]

Pretty sure ANYTHING you have for painting is rated for shop air pressure levels, NOT 4500psi. They would fail in a VERY exciting, and dangerous way.

[@joshuagibson2520]

I only fill my guns directly. Using a YH of course. Takes about 20 seconds max to fill, for example, an Umarex Origin. I dont even use water Nov - March. Im curious to see some fill times of the GX models vs YH. The GX models APPEAR to me to be quite slow. That being said, everything in life is a trade off of some sort or another.

[@danh5194]

Just ordered a Notos as my first PCP gun and am looking at getting the GX CS3-i pump. Do you have any tutorial videos for this specific pump for newbies? Cheers!

[@TargetForge]

Congratulations! the CS3i is a great choice for that gun. I will work on a low level into video for using the CS3, in the meantime check out my library of GX videos I have a bunch.

[@ricko2766]

WOW. nice video. I have that same compressor and it seems to be killing the power converter. Customer service is really great and sending a new one at no cost to me. But WHY did the other one die and can it be repaired?

[@TargetForge]

Hard to say, you could look for a blown fuse but troubleshooting switching power supplies without a schematic and and a knowledge of how they work in a steep hill to climb.

[@wendellscott861]

I sure am interested in your plug and play plug in hour meter kit

[@TargetForge]

Here you go! targetforge.net/shop/ols/products/hour-meter-complete-kits/v/HR-MTR-CMP-KTS-STC-ON

[@DjKProductions]

Thanks for this informative video. Besides the inverter being inside the cs4i, is everything else the same as the cs4?

[@TargetForge]

Yes, exactly

[@DjKProductions]

@TargetForge cheers mate ✌🏽

[@jeffalessi]

We are on a bed of nails waiting for the new video!

[@TargetForge]

Ok Jeff, what did you do to end up on a bed of nails? Lol. Almost time!

[@jeffalessi]

Killing time shopping at the home improvement store until your video is posted, tripped and fell in the nail department and ended up being impaled by thousands of very sharp sixteen penny nails.

[@bigfranksworld]

Good stuff so far. Mostly what I fill is a 9L SCBA bottle from 225bar to 300bar (topping it off) so I can take the bottle out in the field. The Yong Hengs just don't last. Never got more than 10 runtime hours out of one. I have had 4 or 5. I do run extra fans, never let it get over 60c, and never run it for more than 10 minutes at a time. I have been running Royal Purple in the last couple. Wondering how this one would last doing what I do. Thanks for the videos.

[@TargetForge]

Good stuff!

[@BSJ-VT]

Run the correct oil. Not the purple stuff...

[@bigfranksworld]

@@BSJ-VT So what would you consider the correct oil? Everyone has their preferred oil I'm sure. The next to last Yong Heng I bought, in the user manual said "use a quality oil like Royal Purple." Maybe you know more than the manufacture? I have run Royal Purple in many things including my supercharged Mustang Cobra without issue. Please quantify your post on "the purple stuff." Site specifics according to published data. I'm always willing to learn if I have made a mistake or are in error of my real world experience.

[@BSJ-VT]

Mobil 827. There are other similar oils.

[@bigfranksworld]

@@BSJ-VT That doesn't explain anything.

[@TangDynasty1983]

Bill, I found that the meter on my CS4 is not very accurate. In order to reach 300 bar on my gun, I had to turn the needle to about 330 bar on the CS4. Is this common or it's just a defect on my unit? Thank you.

[@TargetForge]

How do you know how accurate your reference gauge is? These are inexpensive analog instruments. You now know the offset, enjoy! Not a defect in my opinion, go fly some pellets!

[@gooderspitman8052]

Hello from the UK, just a quick couple of question, will the CS4 have better longevity, given the grease pot and the water cooling functions?

[@TargetForge]

Yes it does

[@Indictedheart]

YES I don't see a link to the OWL meter and would love to buy the product from you. I am also curious can this GX-CS4 actually fill a 9.0CUFT tank as fast as the AirVenturi Krypton? @TARGET FORGE

[@TargetForge]

As fast? No idea, the AV units have issues with reliability and service support so I steer clear of them. Here is the link. targetforge.net/shop/ols/products/gx4-coolant-illumination

[@TargetForge]

Sorry, here is the hour meter. targetforge.net/shop/ols/products/hour-meter-complete-kits

[@TargetForge]

I recommend both items for a CS4.

[@vicbar89]

Hola como anda. Consulto. Que tipo de grasa (lubricante) lleva el compresor. Y cada cuanto hay que hacerle mantenimiento? Gracias. Si podria específicarme el lubricante. Para ver si consigo en argentina. Gracias

[@TargetForge]

targetforge.net

[@jarroldharrell]

Bill us current CS4 owners all need clarity in the grease knob. Its a confusing mess on how to handle it, how much to turn, and when.

[@TargetForge]

I'm right there with you! working the question with the manufacturer.

[@jarroldharrell]

@@TargetForge thanks Bill. I may be now within the time interval, but I'm not turning it until we hear from you on it.

[@TargetForge]

My current level of understanding is one turn after 6 hrs of operation, which I have done and can report all is well. Only turn it until you feel the grease pushing back, don't go past that. Let me know how you get on.

[@jarroldharrell]

@@TargetForge counter-clockwise?

[@TargetForge]

I just followed the arrows on the knob. I'll look again when I'm in the shop.@@jarroldharrell

[@bigfranksworld]

I'm done with the Yong Hengs. Got 3 hours out of my last one. Granted, I pretty much only use it to fill my 9L tank from 250 bar to 300 bar, but I baby the crap out of it. Never let it get past 60c (or 10 minutes run time, whichever comes first), run an extra fan and bigger water pump, and use good oil. I need something more substantial. Do you think that this compressor would fit the bill? Are you still in love with this compressor? Thanks for all you do.

[@TargetForge]

Welcome to the channel. The CS4 or CS4i are GREAT replacements for the Yong Heng. Yes, still loving the GX units! Using my links really helps, AND lets GX know who is sending sales there way! Win Win!

[@bigfranksworld]

@@TargetForge been here for awhile. Really got into the uh compressors because of your videos. Do you happen to have an adfiliat link for the CS4-model? I'd probably want to buy that model. I did tell a friend about this compressor today and he ordered one.

[@TargetForge]

@@bigfranksworld Here is one for the CS4 and CS4i, Also consider my parts for easily adding an hour meter and a flow indicator light for your water cooling, they really do elevate this unit.
