This is a video that I know most people will benefit from I know that I just did , been weighting for a video like this one to explain this procedure and you did it well Ernest . Thanks buddy .
Looking at your post which is one year old , have you done this tune process and how was your result ? I have my MKII on the way and want to know everything about this PCP to get the best accuracy with a given slug , I will be purchasing the slug power kit to get a little extra velocity !
@@JackAgainski I added the Huma transfer port & the FX slug probe since my purchase with a power setting at 115 bar ! With a 23 grain .218 NSA slug in .22 caliber and a setting of 5 on the hammer adjuster I’m getting 958 FPS ! With this setup I get a 3/8 group at 40 yards and just under 1 inch at 105 yards . I plan on testing a 31 grain .218 NSA slug to shoot @ 940 FPS in the future .
@@JackAgainski the MKII comes with a superior liner that shoots Diabolo & slugs well up to a certain gram , I may need to move up to a heavy barrel for slugs over 28 grains achieving speeds of 950 FPS .
Thank you for doing this video is Ernest. It means a lot to a lot of us. Speaking for myself I personally love my impact and never regretted my purchase, I’m just glad that with FX his help and your master classes I’ll definitely get the most out of my impact. Thanks again.
I love FX so much but can’t own it’s.. but still in love it’s..here in Thailand so expensive...I will follow ur channel keep doing uploads more about FX.. thank you sir.. fan of Fx..
Ernest, this is very nice tutorial clip! Thanbk you very much, this will help a lot to everybody... I hope we can see soon guid lines for every size of pellets and slugs... Greatly appreciate you Masterclasses.
I've watched your entire series, I think it's fantastic. Please do a video on rebuilding the FX Dreamline. I will use that video to make a decision on whether I buy one or not. Thank you very much.
I am about to buy my first FX Impact MKII and am watching everything I can find on tuning. I would greatly appreciate it if you would make a more basic video than this one. Maybe explain why you are doing what you are doing, how the reg pressure interacts with the hammer adjustment wheel, why you do them in the order you did, etc. Why did you start at 920 and then drop down? Where did you come up with those numbers and why? Basic stuff that you guy take for granted, still needs explaining for those of us who are still learning. Thank you.
You are a good teacher for this . It appears to be you have done this more than once . Nice job . Thank you for sharing your knowledge and experience .
@@jwollheim 5 broken cocking levers, 2 valves, bad gauges , poor machining on block caused bad pellet probe alignment, I got one of the poorly chamfered pellet probes too, and the power plenum leaked. I had to pay the shipping on almost all the returns, so I am down hundreds there too. They never fixed it ,after 6 tries I did it myself and now it works. FX are totally incompetent.
Thank you Ernie great video. I will buy a Daystate Red Wolf HP definitely. I do not want get crazy and frustrated like most of the FX Impact owners. If Daystate Team wins most of the competitions there must be a reason. However, thanks for the video it was very helpful.
Thanks Ernie! So much relevant and good info, been struggling to fine tune my slug liner in .22 but this was certainly most satisfying to watch and very educational. Sure I should get my Imact shooting slugs like a beast at no time! Regards from South Africa!!! FYI All other comments/watchers ( if i might call it that ), same goes for crown,dreamline etc...
Thanks Ernest, that's awesome. That's really scientific with all those instruments to calibrate it. I remember when I was in the Philippines I just tried to approximate the spring tension of the air rifle hammer vs the CO2 tank air pressure, and it was a long process of trial and error, and patience. The FX M3 is really amazing, one of the best air rifle so far when it comes to fine tuning and accuracy. Have a great day Ernest and God bless!
This is an eye-opener for a lot of People. I would be very happy if Mr Rowe could make the same video for the FX Dreamline. It would be very nice to know if you can fine tune the transfer port. The wheel on the dreamline only has three fixed settings.
This instructional video is outstanding! I learned more from this single video than from all other sources combined. very well done! thank you Ernest!!
Thank you! Seeing it done is the best way to learn it and although I do not have the Impact I think most of what I saw will help me with my first generation Crown. It would be nice to see this done with the Crown!
The FX's ammunition system is very good, due to this in the rear part of the carbine, even with a 700mm barrel, the carbine is compact and does not lose precision.
Thanks Ernest and FX! Anyone else find the coincidence of the hammerspring adjustment measurement of 18.1 mm for 18.1 grain pellets interesting? I’m sure that none of the other caliber adjustments would line up so OCD! Thanks again.
Just ordered my impact a few days ago and I can’t wait to get my hands on it. I’ve been a little intimidated by the tuning process but now I think I’ll have a handle on it! Really looking forward to emptying a few tins when I get it in! Thanks for this video!
I don't have a meetured device to measure speed yet and I didn't get see the part where you have to have one to make adjustments... Now I know that it's better to NOT at all dry fire the Impact and which the book says its ok on minimum power obviously the book is without your instructions... (that was from other videos ) thnx again Earnest, I am certain that other's made the same mistakes... it is what it is. but thank you.
Damn Ernest you are the Master I have the .30cal Crown and I really wish we had the same info for the Crown as you just did for the impact, Thanks Randy
Thank you for this video Ernest ! Could you please do a video like this for JSB MKII and the .25 cal Crown? Or maybe with the slug liner? After watching and doing what you said I have my crown tuned in nicely. Thanks again. I would still watch if you did a crown video.
I have nothing to do with this video cus im from India and I don’t own this airgun!! Have tried getting it but couldn’t find any reliable dealer and so i have to just watch this whole video and smile.. if only ☺️
It does not appear that Mr. Rowe responds to any questions here, but I'll throw out my question in case someone else may be able to answer it. Regarding the "target" velocity, where did that come from? Is it a mfgr. recommendation, past experience, or was it just pulled out of the air? My second question is, why run the fps over 900, and then decrease it? What is the point or value of doing this? Thanks in advance for anyone willing to comment!
I watched the video and with all due respect, I did not follow the logic behind this either. It seemed very haphazard. I get the concept behind increasing regulator to find a velocity peak, but I don’t see the rational on adjusting the rest unless I am missing something.
Thanks for the video. I thought I knew where you were going with the tune - keep valve and hammer spring maxed and increase reg pressure until 920 fps was achieved and then back off the hammer spring to the ~900 fps range. I was wrong. Instead of backing off the hammer spring, you closed the valve a bit to drop fps to 900 range. I'm wondering why? Seemed to me that a bit lower hammer spring setting would have been better for the rifle. So why the valve adjustment instead?
Thank you! Plz make the same video for 25cal shooting jsb mk2’s 34 grain 700mm barrel! What feet per second do you recommend for efficiency and acuracy! Thank you
Stay below 59.6 fpe for best accuracy AND power combination then tune down, not up, to find the barrels harmonic resonance, which will be between 5 to 6 times the pellet speed at the muzzle, which pellet speed will be less than 78% the speed of sound at 26 degree Celsius. Regulator pressure will be around 145 Bar +/- 5 Bar, maybe a bit more. set your hammer spring preload tension half-way between full and minimum, as well as your valve spring. You will get the best equilibrium once you adjust your regulator pressure to get a hair below 59.6 fpe, now the fun part is to tune down, but not up to find your barrel's harmonic resonance and tune to exactly 5-1/5 of your pellet's velocity at the muzzle. All barrels, even from same lot manufactures one before the other will have different harmonic resonances, although close, but not exact. Besides a chronograph, a set of piezo sensors along the barrel and a digital storage oscilloscope, you can find the eluding resonant frequency, but once you remove the sensors, the resonant frequency will change by I don't know exactly how much, but you can deduce it by shooting groups above and below the tuned down velocity. Your the trainer and all athletes as well as guns are not the same, but this is why we shoot. Enjoy the sport. Stay safe and God speed.
I would like to know this as well. What is fpe? Is that metric? I am chrono at 960 FPS with 25 grain jsbs, 700 mm mkii pp. I am getting sub moa. I assume from where I am I just start working 10 shot groups for each setting on the power wheel, then look for the tightest group, but I don’t really understand the interaction and adjustment of the the two for optimization. I understand harmonic tuning for my center fire precision guns, but I am missing something on these air guns.
Why make your adjustments on the hammer spring adjuster on MAX ? You have no where to go other than other than down I set on MIN then you have the whole spectrum of the cam to increase the pressure which is about 4 mm of travel on the spring You may as well cover the gauge they are so inaccurate and work off the crony
i believe he is trying to keep the reg as low as possible and still hit the target fps. if you start on minimum you would have to crank the reg to 150 to get the same results. i'm sure at max the speed would be way to fast so how are you gaining anything? starting on max you can go down. just my thoughts.
Great job for the caliber 22 Ernest, as usual, but could you give us some références for the JSB Exact King 25.39 gr caliber .25. I mean reg pressure, hammer spring set up distance at the power wheel, optimum fps, ...? And, yes, for a Impact with Power Plenum! I know, it's a great job but lot of us will greatly appreciate.
Hi Earnest, I just got my FX Impact MKII in .22 cal with the new "Power Plenum" regulator. My question is - Do the regulator adjustments you show in this video work the same or are they adjusted differently?
Very good, Please would it be possiable to make an informed type of video with the mk2, with the power plenum. Showing how to set it up, just as in this video.
This is a video that I know most people will benefit from

thanks Ernest ... fx is to be complimented for this "value added" information on the fx impact ... on to the crown ...
Excellent! Thanks a lot for this Mr. Rowe and FX airguns. It sure helps a lot to have videos like these available.
Thank you for your patience with us amateurs, that was an excellent presentation.
You are TRULY thee FX IMPACT GURU! Thanks much for taking the time to share your knowledge!
Thank you Ernest. It is much easier to see you doing it than read somewhere.

Mine has been returned 5 times, it has never worked. They stole $4000 from me and wont give me a working gun. FX ARE SCUMBAGS FUCK FX
Brian T what’s wrong with it

Learned more in this video then the dozen I watched before. Thanks Ernest
Nice to see your video to get an understanding of how it all works out. Thank you
Thank you Ernie great video. I will buy a Daystate Red Wolf HP definitely. I do not want get crazy and frustrated like most of the FX Impact owners. If Daystate Team wins most of the competitions there must be a reason. However, thanks for the video it was very helpful.
A good teacher. Even if I don't own a fx and probably never will. But they sure are awesome guns.

finally someone that knows what their talking about. Can i ask you what your opinion is on choosing a 25. or .30 caliber for 100 yards plus shooting
Thanks for the information i really like the way you made this videos come together. Well done.

very good, i'm brazilian i watch the videos i'll still have a great fx rifle hug
So I can just leave the air hooked up no worries. And itll be the same process per caliber yea. Nice video. REALLY INFORMATION!!!
Thank you for that god helping video, and what an awesome gun!

Thanks for the video awesome 👏
When they say max out hammer spring. Do they mean max out velocity or keep winding screw in until it still in full contact with cam
Can you make a Slug Power Kit FX installation video for DRS (I couldn't find any installation video for DRS)?
Thanks. Please don't forget the crown
Thanks Ernest for the fx adjustments settings can you do the same for the fx crown settings for fps .thanks for 22 cal.
