IN REFERENCE TO INSTALLING A PSI GAUGE ON THE FLYING DRAGON-PCP AIR-RIFLE:
"I'm not at all familiar with the design of the internals, but threading a gauge directly into the tube is likely not a good idea.... Mike did state that the tube was "over 7/8" OD and under 3/4" ID", which indicates the wall thickness is greater than the 1.5mm standard on the QB rifles (which is definitely too thin to thread).... Even if the tube is 2mm wall, I would think that is still too thin.... The gauge on a Disco is threaded into an adapter which mounts in a gauge port block sealed with an O-ring.... On the PRod, the gauge block is threaded 1/8" NPT and the gauge mounts in it directly, which is the method I use on my HPA conversions.... The inside ID of the gauge block is about 3/8", leaving a 3/16" wall for threading.... It does, of course, take up valuable tube volume, and requires a 1/2" hole in the tube for the gauge, and O-rings sealing both sides of the hole....
Another possibilty MAY be to use a "T" fitting on the fill fitting, but that may be awkward and prone to damage, depending on orientation.... You would have to use fittings rated for the pressure of course, not brass plumbing or gas-line fitttings....
Bob"

IN REFERENCE TO INSTALLING A PSI GAUGE ON THE FLYING DRAGON-PCP AIR-RIFLE:
"if you install a gauge it will need to be after the cap in the rifle, the check valve is the last thing the air passes through going into the tube so anything before that will read zero once the pump or tank is removed..."

IN REFERENCE TO INSTALLING A PSI GAUGE ON THE FLYING DRAGON-PCP AIR-RIFLE:
"I guess Mike has a check valve in the front cap instead of in the male Foster.... For the idea of a "T" to work, you would have to remove the check in the cap and use a Foster with a check valve in it.... The idea of using a Disco gauge block would only work if the ID of the tube is the same as a Disco.... Mike stated it was "less than 3/4" ID" because it had a thicker wall....

I would suggest welding and tapping a small piece of metal for a gauge. I would think that should be possible.

IN REFERENCE TO THE FLYING DRAGON HIGH PRESSURE PUMP (HPP), TIPS ON HOW TO USE IT:
Here are just a few Tips for those that are new to Air-Gun High Pressure Hand Pumps or HPP:
There is some minor assembly involved, just try not to over torgue anything when tightening and be sure to tighten the psi guage using the flats of the bolt located directly beneath the psi gauge!
Although today's HPP seals or O-rings are designed to withstand high temperatures, it is still best not to pump to quickly between strokes! Wait at least (1) full second after completing both the up and down strokes!
First, be sure to tighten the pressure relief ot bleed screw all the way in.
When you start to fill your FD-PCP tube, you will notice a large increase in pressure on your first few strokes; this is because your are first filling the base of the HPP and the HPP hose, BUT, once you start filling the tube, you will see a significant decrease of how much pressure you actually start building-up, because you are now filling a much larger area in the tube.
Keep in mind that you are filling on both the up and down stroke.
The higher the pressure, the more effort it will take on your part on each stroke, this is because of the pressure building up inside the tube and is a good sign!
Take a break! If you feel that the pump may be getting hot or you're simply feeling a bit tired from pumping, its perfectly o.k. to fill the tube in increments. If you do take a break, you may want to release the pressure in the hose by loosening the bleeder screw.
The great news is that the Flying Dragon-PCP requires only 1500-psi, which is the recommended max operation fill amount. I'm 5'-8" tall, 176-pounds, 44-years of age and out of shape, but find filling the Flying Dragon-PCP, using the Flying Dragon HPP to be a breeze!
Now, once you've finished filling the tube, its time to PROPERLY disconnect!
You do so by first making sure that the base or bottom of the HPP is on a surface that WILL NOT blast dust, dirt or debris into the pressure relief valve or bleeder valve when releasing the pressure, which should be done by rapidly turning the bleeder screw into the open position, this helps to rid the pump of any moisture that may have built-up in the pump and will allow you to remove the hose from the foster fitting or air inlet fitting. After removing the fill hose, cover the fitting at the end of the HPP fill hose and cover the air inlet fitting on your FD-PCP.
That's it, just be sure to try and keep your Flying Dragon High Pressure Pump in a dirt, dust or debris free environment, especially when out in the field.
Remember not to pump too rapidly!
BE SURE TO FOLLOW THE PROPER CARE INSTRUCTIONS PER THE MANUFACTURER, MM or ANYONE ELSE THAT HAS OWNED ONE LONG ENOUGH TO KNOW HOW TO GET THE MOST FROM THIS HPP!:)
The Flying Dragon-PCP comes with an extra Rebuild Kit, Oil and detailed Instructions.
Remember, everything has its pros and cons, here are just a few pros that come to mind:
No need to purchase a scuba tank-
No refill fees-
Fast, easy and convenient mobility-
Only a 1500-psi recommended fill-
Hope this helps!
Respectfully,
Al.
p.s. if there's more, please chime in, thanks!
Side Note/s: Use the oil that comes with the FD-HPP per the Manufacturers recommendations or Mike Melick's recommendations.
The silver tube that is exposed when the HPP handle is all the way up is supposed to be lubricated, please do not try to wipe the oil, lubricant or grease off of it.
Enjoy!
p.s. Please click on the link for more images and details on how to best use your HPP.

IN REFERENCE TO THE SAFETY (OR LACK OF) ON THE FLYING DRAGON-PCP AIR-RIFLE:
"I'd like to add a little bit of info about the safeties on these rifles. I have one with a safety and one without so I've been able to get to know each. As you may or may not know the safety in these rifles has an issue where while on safe if the trigger is pulled and released when you flip to fire, the gun does exactly that without any help from the trigger. The way the safety works is the rear of the bolt trips a lever on top of the hammer with a catch. The catch does the same job as the trigger sear just from the top side and not the bottom. If you've had the trigger off you've noticed the front trigger screw threads into a floating steel nut insert. At first glance I figured that this was for thread life so the aluminum receiver isn't stripped. That is only part of the design. The nut fits in a slot which gives the trigger group room for adjustment. This adjustment is needed to set the trigger sear location. If the trigger group is too far back when the trigger is pulled the sear gets trapped down and can't reset to hold the hammer. Since the safety is now the only thing that is holding the hammer when it is flipped to safe it let's it fly. If the trigger group is forward enough pulling the trigger drops the sear and since there is nothing in it's path the sear is returned to position by it's spring. I can't speak for every rifle made but I do feel confident in the safety on my rifle after finding this and repeatedly testing it. Every time I move the trigger group back all the way there is a problem. With it all the way forward it's worked perfectly. I did have to do a small amount of clearance work on the stock at the front of the trigger. I also wanted to point out that if you have your safety removed the easiest way to see if the gun is cocked is to note how much resistance there is on the bolt. If the gun isn't cocked the bolt in closed position will easily raise up and down. If it's cocked there will be resistance to movement. This is caused by the cocking pin pressing against a spring loaded plunger on the bolt this pressure helps seal the bolt to the barrel."

IN REFERENCE TO ADJUSTING OR TUNING FOR A GOOD SHOT STRING w/YOUR FLYING DRAGON-PCP AIR-RIFLE, EDUCATIONAL:
"You want to adjust for a shot string that starts out low, climbs about 4-5% to the peak velocity, and then stop shooting at that same 4-5% below the peak.... As an example, a good shot string would start at 800 fps, climb to about 840, and then end at 800.... By adjusting the hammer spring preload and the fill and refill pressures, you will find several tunes that accomplish that.... The most powerful USEFUL tune is the one that does that type of shot string while simultaneously starting at the 1500 psi maximum recommended pressure....
Bob"

IN REFERENCE TO ADJUSTING THE POWER and ADJUSTABLE TRIGGER ACTION:
"So looking over the safeties on the first gen rifles has given me another possibility for power adjustment. By moving the trigger group all the way forward the spring preload is less and the hammer travel is shorter so less power should be seen. If the trigger group is back the spring gets more preload and longer travel so power should go up unless there is room to go to far. I'm ready to test this and see what differences I find but the weather is not cooperating."

IN REFERENCE TO A PROPERLY ADJUSTED PCP AIR-RIFLE, EDUCATIONAL INFORMATION:
"I'm glad to see all this excitement over a brand new, inexpensive PCP, and Mike is to congratulated for it.... The more shooters that get into PCPs the more we will learn about them.... However, the real noob's want to step back and understand there are conflicting forces at work here.... Yes, you can get 30 FPE for 1 or 2 shots if the pressure is high enough and the hammer strike sufficient to open the valve.... However, the first shot will be the fastest, and the velocity decline with every shot afterwards, and this leads to vertical stringing on the target.... Before getting all excited about shooting over 900 fps, take a look at where the Extreme Spread (ES) becomes about 4%, because after that you will notice the pellets dropping at 50 yards.... It takes about a 4% ES at 50 yards, 3% at 75 yards, and 2% at 100 yards before the vertical dispersion starts to be hidden by the overall group size.... If you are only shooting at 25 yards, you can probably stand about a 10% ES, but that is still only 90 fps on a 900 fps peak....
A properly adjusted PCP will start out a few percent below the peak velocity, climb to a peak (with a short plateau) and then fall again.... Achieving that is a balance between the fill pressure, hammer strike, and refill pressure, for any given gun.... So far, I haven't seen anyone adjust one of these rifles to achieve that.... and until that happens, we are only speculating about what their true performance is....
Bob"

IN REFERENCE TO THE QUALITY and MAINTENANCE OF THE FLYING DRAGON HIGH PRESSURE PUMP or XISICO HPP:
"Further back in the thread someone asked about the durability of the Xisico pump. Tony and Al spoke up on my behalf but I wanted to add a few comments.
First are my general impressions which I posted in another thread:
Quote from: nervoustrigger on December 08, 2013, 05:25:15 PM
I've had one for a year and have used it a lot and am happy with it. I finally had to go in a few weeks ago and clean up some gunk that had accumulated at the base of the inner piston. I went ahead and replaced the little O-ring on the end with a Viton type as a precaution and cleaned and relubricated everything before reassembly. I was pleased to see no signs of rust or corrosion, whether it has anything to do with using a homemade air drier & filter, I don't know.
I have since turned the pump over to my uncle as part of his Christmas present along with the QB78D HPA conversion I built up for him. I went ahead and upgraded the inner piston O-ring with a 90A polyurethane as a precaution. I was planning to give him a rebuilt Benjamin pump but I started having issues with it just before Christmas so I decided to hold onto it and give him my Xisico instead. He's no spring chicken so the Xisico is actually a much better choice anyway. It doesn't compress as much air per stroke but as a consequence it is much easier to build pressure to 3000psi. Just takes more strokes. It's about all I can do to reach 3000psi with the Benji but consider that I am 5'11" and 145lbs after a good meal. A tenacious buck 45, though
The other thing I'd like to add is that the Xisico pump is much easier to disassemble. The Benji pump required me to make a bar to fasten in place of the foot plate so I could generate enough torque to separate the tube assembly from the base. I also needed a bench vise to grip one of the inner assemblies to unscrew it (used wooden jaws so as not to mar the tube).
The Xisico pump? I did it at my kitchen table with simple tools. It comes with plenty of parts for a rebuild so I wouldn't worry about keeping it running if you are a decent handyman. Just one caveat. Considering the history of the little -007 O-ring on the Benji pump, I think it's a good idea to have a good 90A polyurethane on standby so when the time comes that you open it up, you can go ahead and upgrade it. After a year of regular use, my pump was still building pressure but that O-ring looked pretty ratty. The reason I had to open it up was because of gunk interfering with the check valve but it did look like its days were numbered.

IN REFERENCE TO ADJUSTING THE POWER ON THE FLYING DRAGON-PCP AIR-RIFLE, EDUCATIONAL:
"I always crank a new gun to the max to see what it will do as well, heck bragging rights are always fun.... But then I next detune it to a realistic shot string and then try and refine it for efficiency from there.... This is particluarly important with a relatively small air reservoir.... I understand this gun is 115 cc (7 CI), so if you fill it to 1500 psi (103 bar) and shoot it down to about half that you have 51.5 bar x 7 CI = 360 CI of useful air.... At an efficiency of 1.0 FPE/CI, which should be achieveable, that works out to a total of 360 FPE, which could be 20 shots at ~18 FPE, 36 shots at ~10 FPE, or 14 shots at ~25 FPE, assuming those figures could be reached without loosing efficiency.... That's the cool thing about PCPs, they have a variety of tunes that can meet your requirements....

JUST A FEW WORDS FROM MIKE MELICK IN REFERENCE TO TESTING, TUNING and ADJUSTING:
"As the rifles have only been out for less than a month it will be abit before someone else also gets the thing sorted...just a matter of time..wish I had the time to tune them but as the work is piling up as it is that will have to wait....the Xisico pump appears to be the same as the Webley Accupump as seen in the brit magazine Air Gunner...sells over there for 139 pounds sterling...."

IN REFERENCE TO FILLING THE TUBE, RECOMMENDED MAX FILL IS 1500-PSI:
"Mike made some comments on pressures in these two posts:
http://www.gatewaytoairguns.org/GTA/index.php?topic=58190.msg557013#msg557013
http://www.gatewaytoairguns.org/GTA/index.php?topic=58190.msg556885#msg556885
Note that CO2 can reach ~1900psi in a rifle left in a car on a hot day...an interior temperature of 120°F. So the XS60C's pedigree as a CO2 rifle coupled with Mike's test results and the information from the factory, I would have zero hesitation in testing up to 2000psi assuming that it does not first valve lock at some lower pressure.
Also, be aware that the maximum fill pressure may fall somewhat if the hammer spring takes a bit of compression set. For example, it may not valve lock until 2000psi when new but after it has been shot a bunch of times (or left cocked for a period of time), it may valve lock at 1700psi."

IN REFERENCE TO ADJUSTING THE POWER SETTING SCREW and TESTING:
(Image courtesy of cwlongshot.)
"I am turning the screw all the way out then running it in 2 turns, if you test it always start with 1500 psi, back it all the way out then run in 1/2 turn at a time and test, when you find the approx. the velocity you are looking for then fine adjust.
Striker spring replacement will help as will adjusting weight of striker and replacing valve spring. It can be a long process but that's part of the fun. Just be careful..."
(From Mike Melick.)

IN REFERENCE TO ACCURACY TESTS and THE USE OF DIFFERENT PELLETS:
"Morning guys!
I took the morning shooting different pellets out of the XS60c in my basement range @ 20 feet. All shots are off hand, 5 shots with scope on 5X. 10 shots per string before re charging, power was about 1K after 10 shots. I have not tuned or adjusted anything on the gun from when I received it. I shot all the different pellets I had on hand that where worth while. I did not shoot any old Crosman super-pells or any Gamos's other than the rockets. (Most Gamos don't do well for me anyhow)
Like most guys I also choose the JSB 18.13g pellets as my go to pellet. But as you will see the guns really shoots everything very well at this close range. A few are better than others but no one pellet is a stand out from my gun at these settings.
Here is that JSB 18.13g pellet target.
Here is Ultra Mags, Super H Point, Barracuda Hunter Extremes, Beeman Ram Jets & Crosman CPHP
Here is Exact Jumbo Monsters, FTS Copper, Benji Diablos, Gamo Rockets & Beeman Silver Arrows
Lastly here is RWS Hobby, Beeman Kodiak, Poly Mags, Eunjins and Silver ACE Pellets
16 different pellets from the XS60c. Maybe later it will warm enough for the chrony.

IN REFERENCE TO ACCURACY TESTING and DIFFERENT PELLET TYPES:
I am not able to transfer the picture/s, please click on the link below to view the results.
It is the 3rd post on the page.

"I just found some more pellets.
Same scenario, 10 shots per charge, 5 shots per pellet/Target and all off hand at 20feet.
Here is Crosman Pointed pellets, Kodiak Copper coated, Beeman Silver Bear, New Ultra mag METAL MAGs & NewBoy senior heavweights
I find loading from the left side VERY comfortable, shooting ten times ten charging is working well but this is before chrony tests and any tuning. I can hear that the first shot has a lot of ''zip''. But the impacts seem to ''sound'' consistent to over fifteen shots.
I want to do some trigger work as this one is not so great... Very gritty, but predictable and repeatable once it breaks its clean but a bit heavy. I am guessing ten pounds.
This Hawk doesn't have a mil dot, I'm thinking I may need to get a new scope but we will see how it shoots at range. Probably 50 yards will be tops for me and what I want this gun to be able to do.
