Does anybody here can share results and settings? I'm interested especially on JSB 18.13 results in HP version... Mine isn't grouping....

Change pellets ... there has been for a few years now a whole lot of JSB 18's that are under size running in the 5.47 to 5.49 in tins most assume are a 5.52

I personally have sent back near 4000 over the last 3-4 years due to this problem. Now days ONLY shoot the AA label jsb's in 16 grain and given up on 18's all together.

Ok guys her goes my heliboard experience. First of all dealing with Jack is a pleasure his responses are quick and he seems truly interested in what other people are doing. My board came just as described and installation was easy other than it's a very tight squeeze for my big fat fingers. I have an Airwolf extreme so it has the longer Barrel and Jack was very interested in what I was going to be able to achieve. With my stock board maximum velocity for JSP heavy King 33.95 pellets was 764 feet per second. by the way all of my measurements are done with my new lab radar chronograph. With the new board installed the same King Heavies on level 12 do 879 feet per second ,level 11 they do 772, on level 10 they do 742 , on level 9 they do 707, and I level 8 they do 658. needless to say I'm thrilled I haven't done any serious testing of shot strings this was just 5 shot groups to get average velocities and believe me the five shot groups are so close and standard deviation I'm sure even a 20 or 30 shot string isn't going to change the average very much. I did also run JSP regular Kings 25.39 at level 12 and they shot 954 feet per second. I will keep you informed after I do some string testing but so far I love it. Tim

Just got a chance to run the Wolf and heliboard with Labradar.

Stock Power level 11 setting / 210 bar

JSB Exact Monster (redesigned) 25.4 gr. : 890 fps, 45 ft/lbs

JSB Exact 18.1 gr. : 980 fps, 39 ft/lbs

JSB Exact 15.9 gr. : 1025 fps / 37 ft/lbs

All group well, but will probably get the 18.1s down to 920-940 for better grouping. (and plink the 15.9s, really only shoot them on the Regal)

Really like the monster numbers.

Great addition to a great rifle.

Thanks dog. I love seeing those numbers like that I wish I had a 22 that can shoot those monsters at 900 feet per second they have the highest ballistic coefficient I've seen of almost any pellet. it makes me want to get rid of my Huntsman and find a mark 4 or Airwolf in .22 and put one of Jack's boards in it I totally love the one I put in my Airwolf. My guess is a wolf would have more potential than the Mark 4 but I love my Mark 4 .177 as long as I could get like you got 890 I know the shot count would be less with a mark 4 but that would make me pretty happy.

So on pwr12 I ran the king heavy mk2 and saw a velocity increase over the old king heavy. Also jack had mentioned that I might try a 240 and 250 bar fill. So I just skipped ahead to the 250 bar fill and I got a solid 20 shot string at 891.6 feet per second average that's 59.94 foot-pounds with a standard deviation of 3.4 and an extreme spread of 12. That isn't going to be my everyday setting I think that's really for only when I come up against really dangerous game like groundhogs. But it's so cool to be able to just flick a switch and have that kind of power on tap can't wait to see a more sedate setting and see how consistent it is I feel like this board is way more consistent than the stock one

Some interesting results today with the Heliboard and Labradar. I wanted to run the 18 gr JSBs from a full charge (230 bar) down to 140.

I thought the board would do a better job of keeping the velocities tighter over the pressure range, but that's not happening. Wondering if this is normal because I never ran the test with the factory board. Here's the results:

230 bar : 980 fps - one nice big hole at 25 yds. ES about 5 - very nice.

200 bar : 970 fps

170 bar : 950 fps

160 bar : 940 fps

155 bar : 930 fps

145 bar : 910 fps

140 bar : 900 fps - correction to keep the same poi = 1 MOA up and 1 MOA left

Does an 80 fps variance from top to bottom seem normal, or is the MCT not mapping as expected?

Thoughts?

Why the board HAS PROGRAMING .... you need to bump up the pulse width a bit at differing pressure points.

Doing that you can get a flatter profile at the power level/s of your choosing.



if Jack Did Not provide the board tuning info ? ... just ask him for it.



ALSO keep in mind that at MAX power it takes MAX pressure & if your after all you can get power wise ? ... sadly the speed will decline with less pressure to fire the pellet.

there's NO free lunch here .... Only when backed down some in power can the valve be operated via the board & MCT tech to deliver a flat string over varying pressures.
