Pewpewpetie Posted October 26, 2020 Posted October 26, 2020 Hi all currently increased the rof and trigger response on my spena arms g01 with 16:1 shs gears and high torque motor. I had already changed piston, piston head, cylinder and air nozzle. Problem is the gun shoots flawlessly in semi( even with rapid trigger pulls) but when in full auto the bbs are coming out maybe 7/8 then a few jam and it clears itself. Chronoed @ 340fps on 0.2g, 25rps and very consistent with a +-2fps. Not sure what the issue could be.
Pewpewpetie Posted October 26, 2020 Author Posted October 26, 2020 Seems I have found the issue. I believe the heat of the bbs passing through the soft maple leaf bucking on a long full auto cycle is warming causing it to create too much friction, thus jamming the bbs. All works fine on short full auto bursts. Maybe I'll try a harder bucking.
Pewpewpetie Posted November 5, 2020 Author Posted November 5, 2020 Turns out my specna just didn't like maple leaf buckings, the lips were too big, stuck a prommy purple in and no problems
DerDer Posted November 5, 2020 Posted November 5, 2020 That's good to hear that you resolved it. Have had good experiences with the purple rubber. Had it work in hop up units that were picky with other rubbers (Bull Gear and Retro-Arms).
