Flying Dragons PCP

[RHytonen]

I posted this pic once (as I had promised to do when I got the GEN II apart)
with a fairly long post in explanation of the shot curve etc. (which I didn't save...)
and for some reason I'm left only to guess, it disappeared.
I never got a notification or an error message.
One more try (just to see what the problem is.)

[Update: It appears the site can't handle a 1.21MB pic.
Unfortunately I haven't had this experience before on a hardware-oriented site
and am AFAIK incapable of taking low res pics.
I never really found them useful anyway, even when I had a cheaper cam.]

If it takes, and anyone has questions about my GEN II, or the shot count (this is a .22, ordered power tuned, and requested and discussed "with no plastic." The barrel band, behind-valve spacer ("plug") and trigger group block, are plastic. It got ten pretty powerful (@ least accurate, more accurate than I am certainly,) shots pumped to 1600psi, JSB 18.13gr Exact Jumbos, before it started to drop at 41yards. Shot #11 was 1/2" low, #12 1" low, and #13 was 2" low The charge went for 21 "shots" - the last few dry fired, before running out of air. It was completely empty on a cautiously redundant de-gas check during teardown.) I think it might shoot the similar weight Kodiaks well also (as does the Benji) but shows some promise with the 25gr+ JSB "Monsters."All the JSB's seem to chamber comfortably on loading. The 32gr. Eun Jins drop badly at that distance though, and they will be my power tuning goal for now. The H&N "Rabbit MagnumII's" (~25gr.) are VERY tight loading and not accurate at all so far. From my recent experience with the Benji starting to prefer the Kodiaks over the JSB's, after over a year, I expect these things to change too. I want to feed it a little more air (with a 22ci bottle at 1600psi and some safety and valve mods) and see what happens. I can almost sense it wanting to wake up and be a little less reserved. I think Eric can help.

No chrony this time, but I've built one that I will try after cleaning, polishing and modding the gun a little. And after building a bench to hold the gun and 1" tube DIY "chrony" in registration. If it works and is usable after tweaking the sw, I'll build one with far more LED's and phototransistors (they're cheap, this one has two and six respectively) in a 6" tube. That should take about 24 semiconductors,  and they're only about $1 each. The tube costs more than that- and the sw is free. It's built for audio (mics) but it doesn't care if it gets photocell input instead. A pulse is a pulse, and light is faster=more accurate.

When I get time I'll consider finding a drop site for pics, and try to notice if there's a favored one here.
I didn't realize this limitation existed when I made that promise, sorry again.

I'm very much wanting one of these... but I don't have a clue about much of what you guys are saying as far as how to modify.  I see why much of what you were doing but don't understand how!

I have had a couple of questions about the fill setup I built with Chinese parts I purchased on eBay.... I made this setup, which I posted earlier in the thread....



I had a problem with the slide check valve.... It kept blowing O-rings.... The rest was fine, but I had to remove the slide check and fabricate a bleed valve, which I did as follows....



I removed the gauge on the side of the ASA valve and installed a steel 1/8" to 1/4" adapter which I drilled and tapped to 3/8"-24 NF for a short bolt.... I made a Teflon (you could use Delrin) insert to seal against the bottom of the drilled hole.... When you hand tighten the bolt it seals for filling, and when you loosen it, it bleeds the air out of the hose through the small cross-hole just visible on the bottom of the bleed fitting (on the smooth portion between the threads and the hex).... This worked perfectly.... I understand that Mac1 Airguns sells a US made slide-check that doesn't have O-ring problems, so that would work also....

Does anyone know if the B-51 stock will fit the XS60?

I know what OTC means - that was my first wish on the FD as well.

Next was the QB/AR thumbhole stock but that seems unavailable at the moment.

I've settled on the AR2078A stock, and yes, they all will take a lot of work from the user, but who has $500 for a STOCK? If I even had $500 to spend I would've bought a .25cal Mrod or Hatsan or something.
It's hard enough affording minimum air supply stuff on a fixed (SS) income.

But new back problems & surgery will not allow pumping my Benji any more, maybe forever. It was getting too hard, for too little shooting, at my age. I just tried it after a few months being idle, and now its power is completely gone anyway. I watched the pellet drop FEET before it hit the ground- at 40 yards on 8 pumps. Some day it will take a cross country trip to Tim (extended billet steroid) if he's still worklng.

It will not.
Even with a LOT of work the Bam tube channel is MUCH larger than the FDpcp

John,

Is the only problem that the tube channel is too large?

Does Boyd's Blasters make a stock that will fit?
