Fx Maverick Power wheels adj. problem

[Marc.france]

Hello

I have problem to setting my Power wheels
tried a setting today, pressure 160/125-130, here are the results:
pw7:940 fps
pw6:920
pw5:890
pw4:800
pw3:980 loud popping noise
Pw2:980 loud popping noise
pw1:980 loud popping noise

What is my problem with 1/2/3 …. I dont understand.

My Maverick is .22 and 11grs hammer

My guess is if that is a heavier hammer, it is too much for the lower power settings.

Marc, it could be your reg pressure is too high. Try lowering it to 120 bar and then slowly increase reg and HS till you get the speed you want with a projectile. Also, you should try tuning it about 5% lower than the max speed (the knee) for the most efficiency. That means at a certain reg pressure you increase the HS it hits it's highest speed then when adding more HS the speed drops, then decrease the HS till you get 5% below max speed.
