Who all runs a Huma regulator in their Fx Impact?

I have one cuz it was shipped off much faster than waiting to get parts from FX to fix my original Gen1 Impact with a bad from the factory regulator rod. Truthfully I did not notice any difference between the two when the FX unit was werqing correctly. But the Huma allowed me to add another spring washer so increase the pressure a bit. The tiny bit of creep I got from both regs was taken care of by firing of a single shot before I got down to business.
 
Just wondering who all runs a Huma and if you like or notice the difference? I'm getting the Huma installed in my ImpactX soon.



Redick:

There are no technical/performance advantages in one regulator over the other...Both valves work the same way and there should not be any differences. The Huma has a BRASS piston vs. a Polymer piston in the original FX regulator. The polymer piston is lighter thus faster reacting times (refilling the plenum) which in reality are unnoticeable to the shooter, the brass piston is less prone to scratches (damaging) when taking apart the regulator for maintenance. The thermal expansion coefficient of the polymer piston is better than the brass, but Huma compensated for this in the tolerances they used. Huma uses an aluminum body with a Brass set screw, FX uses brass for body and set screw; no real advantages in either system (I like brass bodies better than aluminum ones)...Huma and FX are both very good valving systems.

Creeping is a consequence of "Too Many Pressure Adjustments" back and forth...The set screw puts an indentation on the sealing surface material used for closing the air flow pressure into the plenum, and the higher the BAR setting the deeper the indentation in this material; If the shooter sets a high pressure and then lowers the pressure, the indentation will be "too deep" for a perfect seal and this is why and when creeping issues show up...Huma uses a floating 4 mm Delrin disk for sealing, and the only advantage is that if it creeps you flip the disk over and use the other side...Huma comes with a spare disk, so you theoretically have "3 spare" sealing surfaces which should be plenty for many years of operation...

Do you really need to buy a Huma? (Replace the original FX)...The answer is NO, but if the brand name and spending over $100.00 US makes you feel more confident, then this may be an option for you.

The way to adjust a regulator is to start from LOW to HIGH...Start with a low bar setting and slowly increase the pressure until the desired power/velocity is achieved and then LEAVE THE PRESSURE SETTING ALONE.

I notice no difference between FX's reg and a Huma reg except for one difference, the FX reg creeps. If you are ok with firing a couple shots, the FX reg will work for you

I wasn't ok with that. Hence, Huma. Sorry, the fx regs creep. You can tune around it just fine shooting max. But i like to use my power wheel as it was intended. I don't want to blow off two shots for it to settle if i want to use 2 on the wheel instead of max.
 
Finally put one in my gen 2 Impact. Made a 50% improvement. (my estimation) I was having a lot of just where the ? did that shot come from. I had rebuilt my OE reg several times. Ken @ SPAW repaired my rifle a year ago and it's still shooting well . I've had this Huma in for about 2 months and it has put the vertical POI on dot. 

the left right horizontal is just a matter of cant and my bodily vibrations. (and wind) 

I have had the opertunity of shoot with the AMP. Im hoping that FX has made the necessary improvements . I can't see buying $2000 guns you have to work on. to get to shoot well. 

I'd love a straight shooting dependable gun. FX is hard to beat for accuracy. but keeping the Impact shooting has been trying with me.
 
Think there is 2, or 3 versions of the impact reg, all depending on what generation of gun. The huma might be a better solution than the oldest generation FX reg? But I have see some post where some are changing out the AMP regulator for a huma, where the AMP actually perform better. Some has tested the AMP gives a lilte less pressure drop from a full fill, and down to the reg pressure, while the huma may have 5-6 bar difference. I happen to own both a impact X, and a wildcat mk2, with a AMP reg. From a full fill, and down to a litle higher than reg pressure (I do not shoot below reg), both stay within 2-3 bar difference. The reason I know this is because both gun has a EDMU gauge fitted on the reg side. Measuring that difference with the stock gauges would be difficult. But to be fair when comparing a AMP to a huma, the AMP will usually been "broken in", while the new huma probably need some time shooting. But the huma gives great benefit if you have a older style gun, and like to experiment with different pressure, as they are easier to adjust. And if the stock reg is not working properly, it can be a good oportunity to swap it out with an easier adjsustable huma. The huma has one other benefit, and that is they in some guns are smaller, so they give more room for air in the tube, or a bigger plenum space.
