Good job on the FPS. Springs will do that to you, they’re like cheap lipos… rarely what the manufacturer claim they are. But you sussed it and sorted it… great result.
With your misfeeding, maybe check your t piece for clearance.
It’s possible that glueing the thing together has created a restriction somewhere. Maybe a little glue hanging off the inside of the feedtube. Easy enough to check by manually feeding a gel that’s on the biggish side into it to see if there’s a problem there. Easy enough to clean out with a roll of emery paper.
Other than that it can only really be your nozzle clearance in the t piece or intermittent power to the mag motor due to dodgy terminals or a faulty mag motor. I’ve had that before… spent a long time trying to source the problem, turned out to be bad mag terminal wiring.
Good chance its wiring as the feeding problem came and went today. Was dry firing maybe one in 15, now feels more like one in 25. Will check out the mag terminals thanks mate
Did some outdoor testing today at long last, two tests
7.4mm barrel with an Urban gel hop up using Summer Cat Oranges, Greens and the harder and softer milky’s.
Then the same tests with a 7.5mm integrally hopped barrel with the same gels. Winner for accuracy was the 7.5 integrally hopped barrel with Summer Cat Milky’s.
I left the M110 spring for this test at 350fps, next time I’ll drop the FPS down and test again
For reference the fence in the corner was 45m
Calling that a win for now! Again, could not have done this without the help here
With the unfortunate closure of Nuketown my son and I tried one of the Donnybrook school holiday sessions the other day. Numbers were really low but we’d driven 1hr 40mins and this blaster needed a test run so we stuck with it. Happy to report it ran without any issues, no dry fires, misfeeds, no weird sounds, nothing!
Its doing around 26 RPS at 330FPS with a fresh M110 spring, so I’m hoping that spring will settle down to 300FPS to improve the accuracy.
Only problems left to solve is that there doesn’t seem to be enough room in the APS receiver for the fire select components to fit. At present masking tape is applied to the selector plate to keep it in full auto.
Nice work. As I’ve said before I used Wells cyl head, tappet plate, cylinder to get the extra 2mm clearance for gel ball as they are a airsoft box. Fk the delay chip off.
Not sure on your exact model of APS but on mine it is standard V2 for fire select. Make sure that spring is on the selector plate on left hand side and works through to your trigger disconnect. Hard to explain in writing, but if that’s not right, it won’t work. You need that tiny spring on the selector plate or you no get selector through to your trigger block. It’s fiddly as fuck.
