THANKS MIKE , FOR THE FLYING DRAGON PCP , IT IS WONDERFUL .

[rangerfredbob]

Yeah, I talked to Mike yesterday and there were 35 orders in front of mine... money is in his hands and I should have mine in hand in a couple weeks , he apparently just got 400ish more of the guns in...

[Nick Hammack]

Still not up to par and under the weather a bit , I wanted to get out of the house and use an air rifle .

 I grabbed the newest addition to the stable the FDPCP in .177 shooting CHP's and headed to a ditch line that intersected a brushy fence line , not feeling up to par I did not want to take any free hand shots or sneak up the ditch line , so I set up with my shooting sticks .

 I chose the open high ground and waited , just before dark the rabbits started to come out , none close to me so I relocated about 50 yards further up the hill .

 I seen no less than 2 dozen rabbits along this line and could have shot my limit but not feeling quite up to par I felt 4 was all I cared about cleaning and it will make a few dinners besides with a few taters and onions thrown in and a slice of homemade bread .

 The nearest rabbit I took was over 30 paces and the furthest one out was a tad over 60 steps , one shot each is all it took .

 I sure do love my little $100 PCP and will continue to work on it to make it better and will post the upgrades and a tutorial on the break down and assembly of the little gun as well as the parts that I am going to make for it that will correct some things that need addressed .

Great shooting Nick. I got me a bunny today with my 12 gauge. Yummy meal for sure.

Hey Nick.
If you don't  I'm thinking of putting up a Google Site similar to the one I have for the B50 in order to catalog these tips and tricks along with those from others on the forum. See my link below for an example of what I tossed together for my B50

[mouka]

We definitely need some how-to for disassembling this little rifle and putting it back together.
We also need some info on the different o-rings and what needs to be done when the valve locks up.
I am sure there are a few other issues that all of us have experienced or will experience in the future. All of these issues can be fixed fairly easily. But if we can consolidate all the different solutions and workarounds, that would be terrific.
This little gun is a keeper once you get it working the way it's supposed to.
As Nick told me the other day, it's a "nice platform" for would be tinkerers and fixers.

[mouka]

Nick,

Can you please provide me with pictures of you disassembling your FDAR?
I would also like to know the size of the urethane o-rings that seal the valve and its assembly.

Thanks

[smythsg]

Awesome hunting Nick the carrots are safe!

This is a pic of the Flying Dragon PCP valve , notice the spring stand off that I made for the valve .

 


 This is what the stand off does , it acts as a spring guide and a stand off for spring tension .

 


 This is a pic of the stand off mounted in the valve cartridge .

 


 This pic is of the valve cartridge with the stand off installed looking inside .

 


 a lot of folks have been asking me about this and this is the only flaw I have found in the FDPCP which is pretty remarkable , this is a wonderful little platform for the tinkerer and the hunter for the stately price of $100



 Regards, Nick

Did you mill that spring stand, or was it something you repurposed?

[Nick Hammack]

I turned it on the lath ,  not on a mill .


it was out of a alum bar stock lying around , turned and threaded for 6-32 screw for attachment .

 

Regards,  Nick

Oh tonie you can post my stuff to a site if you wish ,  I will put it here and that is all the time I will have to dedicate to it ,  thanks for the effort in advance .

Nick,

would this not prohibit any air-flow to the valve? Making sure there is enough air available at the valve seal for a full powered shot is really important, right?

Thanks!

Al.

EDIT: I know that Mike has taken these types of valves (QB-VALVES) and has taken the poppet, turned it down to fit the spring, so the poppet is a guide in itself. Would something like that not work?

[Nick Hammack]

Look close Al :

This has nothing to do with the valve except to hold it straight in line just like the co2 set up ,  as it came the piercing valve was the spring guide and if we had all the parts for this set up then this part would not be needed.

As it stands we have  a spring that is resting on a washer that has a hole in it just barely smaller than spring diameter and it will eventually cock not if but when .

The guide puts the valve cartridge back to the way it was designed originally , with a spring guide .

I do think all of the guns will experience the valve failure due to this condition like a couple already have ,  this will fix em so it does not happen .

Regards,  Nick

Do you have to remove the air tube to remove the valve?

[Nick Hammack]

No.

[JTB530]

The FD-pcp uses a qb valve that is slotted on the sides for additional airflow. There is a large amount of info available on modding the qb valve for improved airflow to the valve seat in order to ensure enough unimpeded air flow to prevent starving a shot. If you look into the air reservoir with the fill cap removed you can see that the air tube seal covers a bit of the slots and only leaves a small gap for airflow.The slots by themselves only provide a .154 x .276 passage and that's before the seal blocks off some off it. I open the center hole as much as possible and turn down the spring end of the poppet so that the spring fits tight onto the poppet so it can't cant to far to one side or another. There are several ways to "skin the cat" on improving this valve but from my research opening the front side is always desired. It would seem to me that since Mike is removing the piercing pin to improve airflow then blocking off the hole would be defeating this step.

[mouka]

I think we need Mike to chime in and let us know what he thinks about this whole setup.
If he removed the stand off and spring from the CO2 gun, then he probably have a very good reason to do so.
I disassembled my gun under Nick's recommendations only because the gun was leaking from day one. In fact I haven't been able to shoot a single shot with it.
I am waiting for a thicker seal to try and see if this takes care of the leak. I am almost certain it will fix my issue.
I would love it if someone could provide me with some urethane o-rings to use as spare parts for the valve assembly. My gun had 2 urethane o-rings nicked. It might explain why it was leaking in the first place.
There is also an extremely small urethane o-ring on the valve pin itself. It would be nice if Mike would provide us with sizes and maybe even where we can get those o-rings.

Hi Nick,

I'm sorry, I'm late to this thread but I am having trouble understanding how the spring guide is helping to remedy a leak.  I have modified several QB valves so I am familiar with their components and how they work.

At low pressure (or no pressure), the spring helps to seal the poppet against the valve seat.  At normal operating pressures, the spring is comparatively less important as the force closing the valve is dominated by the high pressure in the air tube.

You mentioned that it keeps the spring from canting but I would be surprised if a slight cant allowed the valve to leak with 1000psi or more of pressure encouraging it to close.  If it did, I would be looking at the mating surfaces for a scratch or other imperfection.

Based on the length of the guide, it looks like its main function is to apply a preload to the spring.

Thanks in advance for your reply.  I'm trying to pick up on any and all technical information I can about these rifles because I'm sure to be working one at some point.

The more I think about this, the more I am convinced that my gun leak is related to a seal or o-ring that is nicked or simply defective.
I think that the standoff and spring might be useful if a gun is leaking from the transfer port. My gun leaks from the thread of the tank. So it is probably the seal (urethane o-ring) that is bad. I know that a couple of other urethane o-rings that seal the valve are damaged. So they need to be replaced.
I will see if Mike is willing to send me those as I think it is the cheapest solution for both of us.

Just go to Autozone and buy an O-ring kit. Every thread I see you complaining about your rifle not shooting. Try and fix it instead of posting on the forums, seems like time would be better spent trying to remedy the rifle.

The o-rings in the 60C Valve are the same as the QB-Valve. All of the information is already here in GTA, just got to search for it!:)
