FX Crown regulator updates

yeah its possible to hit a small squirrel in the head at 95-100 yards. Been doing this a long time. You're gonna miss more than you hit. Then if he doesn't drop dead like a stone, good luck finding him. I don't understand how some of you guys determine that the regulator is creeping , if in fact it's only a hair difference in poi. A puff of wind, a heavier or lighter pellet. Anything could cause this hair of a difference in poi. Including the shooter. The other thing I dont get is, if a regulator is set at 140bar,,,,,,and you look at it 3 days later and it says 138 bar, does that mean its creeping, or could a change in atmospheric condition, temperature or whatnot be the culprit? Seems like it could be to me.

Just remove the regulator gauge. Solves 99% of all reg. creep issues...... 😜 .



@dreamsmoker, great results man! Your Crown sure is a hot shooter. Good to see the mod worked out well :)

Alls im saying is we know that the air in the bottle explands and contracts. Explands? Really? Anyway. The bottle feeds the regulator. Though the regulator is much smaller and handles a much smaller volume of air, it too is subject to atmospheric properties. With the two pieces working in tandem, " could this effect be the cause? I wouldn't think it would be enough to see on paper.
 
I do not know how much the pressure in the reg chamber can increase from shooting the gun outside in say 5-10 degrees C, and then store it inside in 20-24 degrees. But what I do know is that when filling the tank on a gun, and you feel it is warm, and then let it cool down to room temp, it is probably not uncommon the fill pressure can drop as much as 10 bar, all dependent on how warm the bottle gets, right after filling.

The FX regulators creep a little over a few hours. They creep on the crown and impact. We know it's just a regulator problem because you can replace the impact reg with a Huma and the creep is gone completely. My impact crept up 20 bar overnight until I upgraded.

Yes. Winner winner chicken dinner. Almost! It all depends on how cool the bottle gets after filling. Now were talking the properties of condensed air.

You see, compressed air is hot. Not cool. Therefore, anytime you fill a bottle, tank , whatnot.......it is not going to read temperature specific until it stabilizes. And here's is a hint. Compressed air never stabilizes. It is at the mercy of ambient condition. In other words you take it out of a controlled environment: It changes.

I can tell you this. A creeping regulator, this does not make.

lol. Sounds like a huge temperature increase to me! I want to see the regulator that creeps up over night. It's doing the exact opposite of what it should be doing, overnight. Unless there's a leak from the bottle to the regulator with which the leak is so small, that the bottle builds slightly higher pressure to the regulator surpassing the leakage. As far as a regulator creeping up 20 bar, on its own in a properly functioning airgun........this is impossible.

My impact regulator crept up 20 bar every night and is a common problem with the impact and crown. https://www.airgunnation.com/topic/fx-crown-5/#post-268857 https://www.airgunnation.com/topic/fx-crown-5/#post-270426

No one said the gun was functioning properly, the regulator was creeping.
 
I can make this simple..

I believe the creep comes from the face between the ajusting screw and the extended end of the piston.. There is where moving air through the very tiny holes in both the ajuster screw and the offset hole at the end if the piston rod takes place until they mate. BV washers allow the gradual pushback on this mated surfaceas to allow you to change that pressure and very the prusher it takes to close.. Otherwise this would be either a open, or closed only valve.. I believe some Creep will always be in this design.. So if anyone has more or finds I am wrong? Please chime in..

That said and add the fact the Gage is not a fine high pressure gage but a gage that is good enough for personal settings.

The Crown and Impact Regulator ajustability is still way ahead of the Pack..

The Huma impact tuning regulator is very similar but can sit at 150 bar for days with no creep whatsoever.
 
I just installed a Huma-Air regulator in my Crown with the washers set at High Power. I have installed regs before but when I put everything back together my reg gauge read zero.
I slowly adjusted it up and got it around 110 BAR and the reg adjustment screw is pretty much flush with the housing. I don't think I want to back it out any further.

Seems strange, so I took everything apart, double checked, followed instructions and still the same result.

Any thoughts?
