FX Masterclass : FX Impact - FPS Tuning 

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.

thanks Ernest ... fx is to be complimented for this "value added" information on the fx impact ... on to the crown ...

Ernest it was a real pleasure to meet you today. I'm reviewing your video in preparation for tuning my new Impact. Good stuff. Thanks Sam;

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.

Thank you Ernest it is a lot of help. As Bob said I know I have been waiting for this for a long time

Love to see you Back Mr Ernest The Master of FX AIRGUNS TECHNICAL 🤩

Thank you Ernest. It is much easier to see you doing it than read somewhere.

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 .

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.

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...

Awesome to see this video. Thanks for sharing! Perfect timing for me 😉

You are TRULY thee FX IMPACT GURU! Thanks much for taking the time to share your knowledge!

This is excellent information. Thank brother and God bless you.

Learned more in this video then the dozen I watched before. Thanks Ernest

Very clear and concise instructions how to adjust an awesome air rifle.

Thanks Ernest for sharing your knowledge, very informative.

Amazing presentation clear precise educational and certainly helped me as a first timer.

Nice to see your video to get an understanding of how it all works out. Thank you

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!

What this Impact needs is "more cowbell". Great video as always :-)

Excellent Ernest!!! Lots of people were waiting for this. 😀 Thank you!!

Ernest is “AWESOME”!

Awesome video Ernest thank you for sharing your expertise very much appreciated

Great video , I finally feel ready to tune my own Impact . Thanks Ernst >

Thanks Ernest. I appreciate you doing this video.

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!

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 .

Thank you very much for taking the time to make these videos 😉🖒

Thanks for the information i really like the way you made this videos come together. Well done.

Best video for Fx Impact ever!!!

THIS VEDIO is great I learned a lot about precision adjustment on such a fine Air rifle Thank you Sir

Awesome!!! Thank you. Had to watch this a couple times.

Ernest thank you so much for this great video, watched it a few times excellent!

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..

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.

Thx for taking the time FX Gang. Just loving my Impact Mk2 PP to bits.

Thank you, Earnest!!!

Very good demonstration! Thank you.

Ernest Im glad Cronk set mine up 😜 I am great full for your knowledge. Wow this is a-lot of tuning knowledge

Big fan. Thanks Ernest.

Lovely job Ernest 👍😎👍

Thanks Ernest, great video and information!!!

Cool video Ernest! Like all ur videos👍🏾

Very informative...thanks Ernest...👍

Thank you, well done as always

excellent Video now I know how to adjust my FX Impact in a way that makes sense thanks !!!

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

A good teacher. Even if I don't own a fx and probably never will. But they sure are awesome guns.

Thank you for that god helping video, and what an awesome gun!

Awesome video. Thank you!

this was very helpful. Thank you for your video !!!! thumbs up!

Hello Ernest, thank you upload this video, this same procedure is for the FX Crown?

thank you for these videos

Very well done, thank you so much

Amazing presentation

Perfect. Thanks for the information

Very Informative..thank you!

Nice video as always!

Awesome! Can you PLEASE do this for the FX Crown?

Thanks Ernest

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.

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.

*Hello, good jobs, great videos.*

Thank, very helpful.

Wow Great Video..!!

Mr. FX Pit Crew getting done and sharing the wealth.

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.

So I can just leave the air hooked up no worries. And itll be the same process per caliber yea. Nice video. REALLY INFORMATION!!!

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.

Thanks for the video awesome 👏

Ernest like a boss : ... Lok at the numbers 😎

very good, i'm brazilian i watch the videos i'll still have a great fx rifle hug

Great info

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

Great sir

Thank you .

ty ernest

Great info! Thanks Earnest! Great starting point for tuning. I know I'm late to the party but can we get a Dreamline w/ power plenum tune? 😉

Thank you i really needed this video. But why dont you use the hammer spring wheel insted of the the hammer stop to adjust?

Hi great video just what we need it’s always a bit scary adjusting things, can I ask what different settings I need for .30 please.

Amazing

Your videos are excellent. These have really helped me enjoy my FX! Please tell me what brand of gun vice you show in this video. Thanks!

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.

Wow perfect sir

This instructional video is outstanding! I learned more from this single video than from all other sources combined. very well done! thank you Ernest!!

How i wish FX impact will be available in the Philippines!

Thanks Learned lots here! Curious... what would i use the hammer spring adjustment wheel for? since the adjustments are so course? All these tune videos show it on max. the set screw appears to bias the hammer spring tension between the the course settings like 4 and 5 or 5 and MAX. But why make the hammer spring wheel with such course adjustments? a redesign of the gun so i can fine adjust without need of Allen key (and taking off the stock, Crown) for example

Absolutely brilliant. So clear and easy to understand and do ourselves. I have couple questions. In uk we have to stick to sub 12ft/lbs. Would you say this is still worth doing for us? I know my given pellet weight so could easily find the fps I want to achieve. Also on my impact m3 I set the micro adjuster but after about 50 pellets it’s moved in and I have to reset it. Is this normal? Should I put a drop of locktight blue on it to hold it?

merci pour vos précieux conseils un papy de Normandie (FRANCE)

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

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.

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?

Can you PLEASE do this for the FX Crown

All great tips Ernest. Having a micrometer and chronograph are a must when tuning. Next up barrel indexing. lol

When will you have these for the Dreamline??

Great video. Do you have one for the m3? I may have picked up enough to adjustment I need. But if not m3 please

Genious !

Thank you for the video. I just received my barrel change kit (.22/500mm) for my Impact X MK2. I am going from a 600mm .30 to a 500mm .22 and I have a couple questions please sir. Since I will likely be going in the opposite direction to what you presented in this video do need to unscrew the bottle before each/every/any time I adjust the reg pressure down (clockwise)? In going from .30 cal to .22 / (18 gr pellet) and the shorter barrel, would you start by lowering the reg pressure from its current setting of ~145ish to around 130 -135psi and fine tune downward or would it be better to initially drop the reg more and work my way up (then back down) like you did in this video? What would I do initially with the hammer spring for each senario? Thank you for your time.

I’m watching this and I don’t own an Impact ..... must be planning on buying one ! 😂
