    Tuning FX Impact Original, Regulator

    Never noticed creeping, only reason I opened up reg was to solve tank dropping to reg setting over night after I installed Power Plenum. Tank only dropped to reg level when reg was set to low pressure, i.e. 90 bar. Once I saw regulator end I figured something was up there also. Watched an...

    Tuning FX Impact Original, Regulator

    Ok, I give up, what's the trick to installing C38 o-rings on C37 (regulator screw)? My original Impact has a regulator screw with a tip in the center which mates to C34 (regulator rod). I broke 6 new 2 X 1 mm NBR 90's and managed to get one installed. Tried to move the one I was able install to...

    Tuning FX Impact original w/Power Plenum upgrade

    Swapped in the FX Power Plenum kit on my original/MK1 Impact. Now when the regulator, factor original, is set below 100 Bar, for example 90 Bar, tank pressure leaks down to 90 Bar overnight. Over 100 Bar, for example 110 Bar, pressure in tank holds, no issues. Thoughts, recommendations...

    Original FX Impact Plenum

    What options are available for enlarging the plenum on an original FX Impact. My highest priority is increased shot count, second velocity. I have both the 22 and 30 cal configurations. 22 used mostly for target shooting and 30 for ground squirrels.

    Youg Heng to FX Impact

    Glem, the thread pitch is different between the Fx connector and black housing. Connector will thread a fair distance into the housing outlet but starts binding against the threads before seating against the housing's o-ring. PingeonMan, threads don't appear match. Maybe with thread tape it...

    Youg Heng to FX Impact

    What fitting is recommended for connecting a YH to Impact? Until my tank blew a seal I've used a long female quick connect fitting, purchased from Best Fittings, connected to the hose tank. This fitting has male threads which does not match up with filter hose's female. Likely something to do...

    O-Ring Size Between Valve and Tank

    Did the 22 x 3.5 duro 90 work? Mine blew yesterday and can't find o-ring specification. My threads are 7/8" (22mm) and gasket set depth on bottle 0.1" (2.5mm). Bottle o-ring seat is ~28.3mm. I crammed a Home Depot 15/16" x 1/8" o-ring. Held for about 12 hours then started to leak. The 3.5mm...

    Yong Heng, parts or alternative

    Decided to change the oil in my YH today. Figured I'd open up the crankcase to see how the crank parts are holding up. All looks good, however unit on has 5 or 6 hours total run time. Attempting to place the crank case cover back on I ran into an issue of the gasket membrane being a little too...

    JSB 22 cal 18.13 gr Ballistic Coefficient

    Based on continued analysis using ChairGun, it appears that the G8 profile best fits the 100 yard velocity data taken at 40, 60 and 100 yards. M #2 = Measured data from second shot M #3 = from third shot GA calculations are with BC = 0.0222 G8, BC = 0.0283

    JSB 22 cal 18.13 gr Ballistic Coefficient

    Just watched AEAC's review for the 22 cal FX Dreamline. During video, velocity data for each shot was presented. For 50 yard shots, speed at every 10 yards was given and for 100 yard shots every 20. Using ChairGun and making some assumptions, ballistic coefficients were arrived at by iterating...
