The Huma for my Impact arrived today, and I was quite anxious to get it installed. My .25 Impact was not performing at all like I wanted it to, or anywhere close to how my Crown performs with the same JSB pellets.
I had never removed a regulator from the Impact before so I reviewed the AoA, and FX Master tuning series on YouTube. The removal of the old regulator was straight forward and I had it done very quickly.
The installation of the new regulator took me some time, but this was due to my nervousness, and the fact I wasn't too careful removing it from the packaging (more on that later). If I have need to do it again knowing what I do now, it would take me a very short time indeed! It's quite simple.
So, the installation was a snap however, after putting the gun all back together I ran across something I absolutely hate, and should be changed ASAP.
The FX regulator uses hex wrenches for both the regulator housing, and the regulator adjustment screw. The Huma uses a straight edge. I really didnt think about that too much while I was putting the Huma in, but later it became apparent to me that this was absolutely idiotic.
To adjust the Impacts' stock regulator you use a hex wrench with a ball end. You come in at a bit of an angle, and it clears the trigger just fine. It's easy to make whatever adjustments you need without a lot of messing around. This isn't the case with the Huma at all. Since the reg adjuster uses a slotted screw, you cannot easily adjust the reg in a timely manner, because the trigger is in the way, and it's likely you'll scratch up the reg housing. I'll have to look into modifying a scewdriver for this purpose, but I shouldn't have to!
As far as performance of the regulator goes, I'm not sure it would be fair to comment too much as I'm sure it will take some time to "break in" and settle down. I can say that after running 78 shots thru it, giving the Impact a quick tune, the next 26 shots were:
According to my ProChrony:
852 Average FPS
19 fps spread
5 fps Standard Deviation
This is with a FX Impact, 700mm barrel, JSB 33.95 MK2 pellets, 130ish bar reg setting. The Impact is the most recent model immediately prior to the "X" version.
I was getting better performance from the stock FX regulator, but I'm sure the Huma needs to be broke in, plus I have to slow the average FPS down to where I prefer it (835ish fps), and I will be using the LabRadar at the range to finish tuning.
Notes:
Be very careful opening the package! There a some very small, nearly invisible bits, and also the little BV washers will come off the reg piston as well.
