ok, after doing a real in-depth analysis of the problem i have come up with the source of the problem, it's two problems that come together seemingly as one,

1. i do have some failiure to feed (magazines are good, and i have tried _many_ ) due to the slightly longer-then-spec distance between the magazine catch and hop unit.

2. the real 'wow' is that when i run this beast on LIPO (11.1V) the air-nozzle ends up blocking the entry for the BB into the HOP chamber (from feed-tube to chamber, where the air-nozzle does it's back-and-forth business) after each shot.

BUT when i run it on an old G&P 9.6V NiMH it works almost flawlessly, (almost, the feeding is a bit off but i'd put it at 5-10% tops) and when i look at the gearbox, i see that the piston is pulled back about 1/3rd of total when using semi on a LIPO and is in the fully-forward(or almost) when using the 9.6.

I WOULD GUESS that the LIPO is causing the gun to cycle too fast, the gearbox is running triple-torque (or more) gears plus magnum motor, and it seems like this setup doesn't like LIPO.

moral of the story, trace the journey of the BB when you have a feeding problem and you'll find the culprit of your problems.

i will still modify my old hop unit to see if that eliminates my feeding problems, and put my Prom chamber in my M4 so it doesn't go to waste.
