Hatsan Flash-R QE question

[avator]

Here is my non regulated gun for comparison.

[Blowpipe Sam]

Thanks Bill.  I'm shooting 20.06gr FTT but after twenty shots it's clear it likes heavier pellets.  I switched to the 25.39gr JSB Kings and the 15 yard group tightened to one small hole.  Tomorrow (if it's still holding air) I'll chronograph it.  I shot one magazine of ten to see how it would function and then maybe another 20 shots with the single shot tray.  The gauge has dropped from 2,500 PSI to about 1,800.  For my purposes the QE moderator works just fine.  It may sound loud to some folks but with a heavy pellet you won't hear it 100 yards away in the woods.  I stuck a huge old CenterPoint 4-16X40 on it.  The scope matches the proportions of the rifle.

Flash-QE and FlashR-QE are two different rifles that share some parts.

I wonder would if the regulator work in our unregged Flash guns. Probably need the whole tube assembly because of the guage.

Just had a Referb Flash-R QE delivered yesterday
Have to say it is a Long Gun, having the 23" barrel.
noticing that there is a circular cut out in the forearm where the Flash manometer gauge must have gone.
Haven't started anything on it yet, just Following,

So far I hear even being QE it still has quite a Bark to it

Curiosity, has anyone opened it up for any regulator adjustments ?

From what I've read, the regulator is not adjustable.  I could see it when I had the air cylinder off trying to get the Fill Valve off and did not see any trace to adjust it.  I did not take it off to see if there were any adjustment on the inside.  It says it's set between 125-130 BAR, but I'm not sure how you'd actually know what it's set at or what it would be adjusted to if there were an adjustment, since there is no gauge for the regulated side.

I hope yours hold air!  I think what happened to mine may be a fluke.  I'm still waiting to hear from Hatsan.  I may try using a heathen on it this weekend and see if I can get the fill valve off.  If so, it looks like it's just one 0-ring needed to fix it.  I may need to replace the larger o-ring that seals it to the air cylinder as well, if it gets damaged during the removal.  A project for another day...

Have you ran it over the chrono to see if it even needs adjusting yet? Or to at least get some baseline numbers.

haven't started anything on it yet, just curious which version regulator they are using

If they are using their AT44 (H) it's factory set at 125bar, and adjustable, which has to be removed to adjust,
also there is an early and a late version having to do with different design o-ring location

Threaded end-plug holding the fill-check-valve is likely secured with threadlocker. Heat with a hot-air gun until it is too hot to hold (~180-200deg F).

That temperature should not damage any soft-seals but will soften threadlocker.

Then breaking the threads loose should be much easier.

Thank you!  I gave this a try, actually got too hot to touch and still could not break it loose!  I even had a probe in the fill port and that is a vice so it wouldn't turn and was using a rubber pipe wrench to try and loosen it and it still will not budge!  Gary the Gorilla at Hatsan must have put the Fill Valve on this one!  I'm done messing with it and will wait to hear from Hatsan.  Unfortunately, since it's already Friday evening with no reply, it will probably be sometime next week before I hear from them.  I'm hoping they will just send me the air cylinder and fill valve assembly and let ne send this one back in the same box.  It should be covered by warranty, so I'm hoping for the best!

Wasn't there a member here that worked for Hatsan?  I wonder if he's still a member?  I may be confusing he with he guy that works for Umarex...   If we do have a Hatsan Employee as a member here and anyone knows his username, please let me know.  Thanks...

Paul.  I sincerely hope (for my sake as well as yours)  that your problem is a quick and easy fix. I don't know how you feel about the aesthetics of this rifle but while I don't think it's the ugliest thing Hatsan has ever produced it is recognizably a product of the Anatolian Iron Works.  Compared to another regulated budget PCP rifle, the Pinty carbine, the Flash-R QE looks like a crude collection of poorly matched after market parts.  If the Pinty carbine had been available in .25 caliber I would have been one of the first on that bus.
The Hatsan has its obvious short comings.  It is looooong!  It would not be fun to wrestle through some of the thickets I hunt in.  However, it seems monolithically built.  The ergonomics are excellent (if you are 6'6" and have arms like a gorilla like me).  Even with the monster CP scope it is surprisingly light.  The seat of my pants says it's powerful.  Pellets make a healthy smack when they impact the disc blades I armored my backstop with.  As always it took me too many pellets to zero the rifle.  This scope had previously resided on a springer with some mild droop so lots of elevation had to be cranked in.  Tomorrow Ill fine tune the zero and chronograph some pellets

[avator]

Carter...
That spreadsheet I posted is for my non regulated Flash. You should get several more shot from your regulated gun but I doubt you'll get the power that mine gets at the top of the bell curve. With an 18 gr pellet you should be in the 860 tom 880 fps range. That's just an estimate on my part.
I'll look a little closer at my other data.

[Rat Sniper (AKA: PaulT58)]

Yea, it's ugly, but at that price point, it's a pretty good deal!  That is if I get to keep this one and can repair it and get it operational.  My past experience with Hatsan CS has been generally positive, so I'm hoping that continues. 

It is longer than I expected it to be, which is why I have Rocker1 sending me some of his baffles.  With mine being .177, I suspect it's pushing pellets much faster than you .25!  The sheet that came with mine said it chronied at 1025 FPS shooting 9 grain pellets.  Mine died before I could get it on the chrony, but the 10.5 grain CPD's were making a pretty loud bark.  I had some of Rocker1's baffles laying around, but they were a tad smaller than the baffles that came it it, they were 20mm diameter, the OE Hatsan baffles are 22mm.  While they worked, they did gaus a significant POI shift which may have been for improper alignment.  But, while accuracy was negatively affected, the sound lever dropped significantly!  I suspect the proper sized baffles will improve accuracy while significantly reducing the sound output.  Also, the inside diameter of the OE Hatsan Baffles is probably around .35 caliber, typical one size fits all mentality!  The Rocker1 baffles were sized considerably smaller, probably .20-.22 caliber.  But, since the dang thing is so long, replacing baffles if the way to go.  Adding a LDC to the end of that thing would defeat the purpose of having an airgun, it'd be long enough to just smack whatever your after!  Also, if you remove the shroud completely, the end of the barrel is threaded 1/2UNF, so a LDC will screw right on if needed, but the QE Shroud provides a tensioned barrel and looks much better!

He's got a .25 caliber, so will probably be shooting the 25 grain pellets.  Which at 860 - 880 FPS would be packing quite a wallop!

LOL... glad I saw your post before I hit send on mine... I had him all planed out based on .22.
But yeah, I get 862 from an 18.1 gr pellet at 2k wher I stopped my string.
I have never been inside this gun but I may be able to use the BStaley to flatten that curve some.

[Blowpipe Sam]

As I wrote, I've been shooting 20.06gr H&N FTT.  Once I generate some numbers  I'll be able to see any correlation to Bill's graph.  The actual values aren't as important as the trends.  I'm hoping for the velocities to be close though.  This thing has 22" of barrel after all.  Hatsan claims "up to 40 fpe".  A couple of reviewers have claimed more. 

[avator]

According to the spreadsheet I can tether my 60 minute tank to the gun at 2700 psi which is the average on my string (891 fps) and shoot all day at near 33 fpe. I'll post an accuracy group pic tomorrow but it was quite impressive today. The gun shoots way better than I can.
A 125 bar regulated .22 gun should get around 40 - 45 shots at around 29 fpe.

Being a .25, I don't doubt that at all.
I can tether at 3k and get a good number of shots at 39 fpe.

[Back_Roads]

 A general rule of thumb regulated .25 cal. not brand specific will generate 850 fps with 25.3 gr pellets. any more power wanted might as well tune a non regulated version. or deal with lower regulated shot count, matching a non regulated shot count in the sweet spot.

Paul, Thanks for the Pic

Yes that is their AT44 latest one, and adjustable
being tight is most likely due to o-ring,
since it's been factory set without any reference marks to indicate your starting point of 125bar ,
you would have to remove it, then unscrew the plenum (silver collar) from the valve,
then you can scribe or put index marks for referencing,
you might get lucky by just trying to unscrew the valve from the plenum,
by putting a wrench on those flat notches

Hope this Helps

Bill,

I did put a wrench on those flat spots and tried to turn it, it too, would not budge!  Hatsan't infamous Gary the Gorilla strikes again!  Not a big deal for me, it's a .177, so if it's shooting the 10.5's above 900 FPS, I'm good.  Chances are, if I need to change it it will be to lower the pressure setting, but I may be able to adjust FPS with the HST adjuster as well, it's a bit more accessible!  Thanks again for your help!

I do understand the frustration, and caution taken not to damage anything,
But if you do decide to make another attempt toward the the regulator,
might I suggest using a heat gun or hairdryer on that plenum
where there's this troublesome o-ring seal that needs a little heat allowing to be broken
once that's done some o-ring silicone grease will make it easier on next adjustment
