Don't know who bob Ross is, but Terry's videos on the drs have inspired me to get stuck in to the tuning side of airguns-( I wouldn't dare mess with my Daystates!!!)
Anothr cracking video Jeff, great explanation as always of how things fit to gether and how they work, brilliant watch, thank you as always for your time in doing these for us, Cheers 👌👌👌👌👌👌👍👍👍👍👍👍👍👍
Have to thank you for taking the time so provide such explanations in a clear video. This explains how the rifle works and I've changed my mind on one, so I’ll be buying one. I’d fit a new rifled barrel as standard but I don’t like FX barrels/sleeves and don’t like that there is the same temperamental o’ring arrangement between such. Even with a thicker rifled barrel, I'd look at a couple of de-pingers, possibly under spring pressure, to both inside wall and barrel in order to help with barrel harmonics/movement. The brass hammer spring guide could be slimmed and a delrin top hat sleeve fitted over to combat future rubbing and fouling. Haven’t seen the block but could a new valve seat be produced, without the large opening, so that there is less wasted air pressure (filling the large current volume of the valve seat) when air passes between valve pin and transfer port? Seems unnecessarily large, presumably one for all rifles of any power.
Excellent vid, very informative. Many thanks. Saying that though it's confirmed my thoughts on this gun, I'll be avoiding it like the plague 😊. A few years ( or even sooner) me think's there's gonna be a lot of poorly rifles that have been messed with trying to replace the one of many seals 😮
Nice work Jeff, a bit surprised there’s no carbon barrel liner liner or whatever FX call it fitted as standard. I found slight improvement in accuracy and consistency when I fitted one to my Dreamline FT. Great video as always 👍
@@sub12airgunners O ring hard as hell, luckily a spare was supplied, and he lubed it up if you pardon the expression. You would think they’d supply a dust plug too, but that’s FX for you.
Thanks, interesting video as always! Seems to me the machining is a bit rough on these and there seems to be more "leftovers" and marks from it. Accuracy issues in my opinion come from their lack of tuning/adapting for sub12 shooting. You might find the liner is a "heavy" slug liner, 1:18, for your use a pellet 1:24 liner would be much more accurate. Might be worth a try. Add the carbon sleeve while you're at it, it helps a lot with barrel harmonics. I've been chasing small and slow leaks on my Maverick lately. Fix one, next one pops up in a short while. Rifle is from 2020 and has had around 30k shots fired through it with no problem at all up until this began, other than the cocking rod bending slowly over time, which i replaced with a titanium one about half a year ago. Simple matter of maintenance in my opinion, i'm going to take the rifle completely apart to replace all the o-rings and that will most likely make it last another 3-4 years without any leaks. The complete o-ring kits are very cheap, so i'm not bothered by it at all. The rings i've replaced so far were the plenum body one closest to the block and the one before that, the second regulator body one (replaced the reg with a Huma one while at it, very satisfied with that one) and the tiny valve pin one. The rifle has been shooting at high power all its life so far, in .25 and .30 at 80 and 130 ft/lbs. My standard distance is 95 meters and its sub-moa with ease. Mod parts as far as internal/performance are the Huma reg, carbon liner sleeve, better gauges, 300bar bottle, hammer spring and the hammer.
I see that you are also a very professional enthusiast. Like me, I designed the fx structure fifteen years ago. EAE has a left-hand loading structure, which was also designed fifteen years ago. Which country are you in?
Great video again, it's a very interesting rifle this is. I wonder if Fx will do a twin cylinder version, over and under style with the bottom one slightly shorter. I'll give them 3 months to think about that one lol.. Great work again. 👍
I am an airsoft enthusiast in China. The structure of fx drs is the structure where the barrel is inside the air reservoir. I designed it fifteen years ago. It’s just that it is an illegal product in China and cannot be processed. So gave up. . I also have an idea here, which is an open hammer structure air gun. When the valve block is rotated, the chamber is loaded at the same time. Which air gun company of yours designed it first, it is also the latest structure.
again fx are pretty good for taking apart this one no exception . perhaps a little bit if you magic barrel polishing may also help . will be interesting to see if it goes back together and is a tad more accurate. what does amaze me is fx barrels . buddy of mine has one of those and it’s accurate. how ever lot of the boy have had impacts and some were excellent and some are not so good . pretty sure the barrels are not very consistent . weather it’s there manufacturing proses who knows .
Hi, Would it not be advantageous to create a sleeve for the transfer port to help with efficiency ( keep the expansion behind the pellet ) as that does look to be a large transfer port for a .177cal rifle.
Great video. Well put together and much better than most found on UA-cam. Have you managed to get it back together and test it yet. I've been debating purchasing one of these myself. How bad was the accuracy you were experiencing? I was debating a .22 version to replace my old but still going strong air arms s310. Just fancy a change really. Looking at the solid block that is the plenum blank . It looks like you could put an adjustable volume adjuster into that which would allow finer tuning perhaps? Anyway thanks for the post really good👍.
Quick question for you. What size threads are used for the main pressure gauge on the block is it 1/8 BSPP? Also I love your videos I’m so glad you made this ❤
How do I know how I have to angle the valve seat? Just changed the inner o-ring because of a leak, but I cannot find any explanation of how much to angle and which direction to angle the seat
Aup mate. Wondered if you might have an idea. My fill probe went bang the other day and since then my rifles extreme spread has been around 45fps. Took it apart and found no issues, took it to the range and it would settle on 698 for a bit, drop to 666 then back up to around 705 and now it's staying there with a 5fps extreme spread. Any idea what could be causing that? I'm going to keep the chrono on it at all times for a bit to see if there are any changes.
Hello, maybe you can help. got myself a new FX DRS and a hand pump, but i can't get the air into the rifle, any idea what im doing wrong? :( (FX pump too) Think the air is leaking around the connection into the rifle.
Can you recommend a gauge to check the plenum pressure on a DRS. I'm replacing the solid sub 12 with the standard one. Many thanks. Ps great content very informative.
I'm new to the airgun world what is the difference between the regular plenum, and the high power one if the regular plenum is just a block with no volume they say one is so many cc and the SHP plenum is more? Why didn't they just make the block thinner and then they wouldn't have had to cut the stock out for it?
The plenum is the chamber where the rifle gets the air from .the regulator is the part that fills the plenum from the cilinder or botlle.to a set pressure .so the rifle shoots with the same pressure
@@HD-ph1dc you fill the gun cilinder with 235 bar .the regulator brings that pressure to 100 bar or so(or less or more where the law has a max legal power output )in the plenum .so you get a constant pellet speed .til the gun cilinder pressure get under the reg pressure .and then you need to refill the gun
This is the same gun as the Pro and all the pro's have the tall plenum. Maybe is so they can just make a cheap stock for the classic and shove a pro style assy into it with different barrel lenghts and sell for $1300 cheaper to get some rifles. The classic in a 700mm is a pro minus slug kit and trigger.
Interesting air rifle to see inside. Bit hard to tell on screen but the machining doesn't look too bad on them. Not the worst built rifle I have seen, although the loose valve plug did make me chuckle.
What caliber is that rifle ?, please. I am trying to make sense of the regulator disc count. I am seeing 8, 11 and 12 count so far for the DRS classic. I see that rifle has 11. Mine is a .25 cal/700mm sold in the USA and it also has 11. Thanks
There seems to be a large variation in accuracy with these guns, what I will say is I got mine a week ago it’s in walnut it has an a-tec wave moderator and a hawke compact scope and I picked up a box of qys domed not knowing if they were suitable and at 30yrs I’m getting pretty much pellet on pellet…..and though I’m sure it’s because the gun is fun to shoot I seem to get through a load of pellets without realising it but that’s an illusion is just because the rifle is a great crack to shoot and for £1216 including new scope moderator and pellets this rifle is hard to beat…..saying that I’ve already been lured by another rifle the FX CROWN MK 2 and while I’m speaking of the fx crown can anyone tell me if it’s worth putting a 600mm barrel on the fx crown mk2 in sub12 ftlbs or should I stick to the standard barrel that comes with the rifle.
Manufacturers sometimes rush products into production, foisting potential problems onto the buying public. Maybe just sending them out to independent testers like your self would be a good idea.
Sub 12 UK - 'make sure there's no air trapped inside the plenum'. Well I'm told that the 'plenum' is completely false and only a solid block of metal. What's the truth please??
Fifteen years ago, I also designed the current EAE airsoft model, which has a left-hand loading push rod on the outer ring of the gas cylinder. That is to say, after firing, there is no need to use the right hand to pull the bolt. I thought about and designed the mechanism of loading the gun by pulling back with my left hand fifteen years ago. Because it is a contraband in China. My design cannot be implemented. . . I'm depreesed
When compared to other rifles, with quality parts and simple design, I'd say it was good value for money. I'm a critic of FX, don't like the DRS breech block design, but wouldn't describe a couple of niggly issues, far fewer than most rifles have, as rubbish.

I am thinking of owning an FX. Just wanted to know, what is the lifespan on one before you have to replace parts?
