The Type 89 motor was quickly swapped out for the Lonex A3 motor. A test fire immediately blew the fuse - standard Marui 15amp. I swapped it out for a 20 and it blew as well. The 25 works fine! The motor is obviously drawing between 20 and 25 amps. I haven't checked the rate of fire but it sounds fine. I noticed that even at maximum the hop was not lifting the 0.25g bbs as well as it should. I popped the barrel out and everything looked fine but obviously, the hop wasn't being compressed enough. After a bit of head scratching a couple of layers of insulating tape on the end of the hop that pushed on the bucking and we were good to go. After some test firing out the back garden I returned with a suitable grin. Perfect.
Fitting the parts for the G3/MC51 were next; a Marui hop, and a Lonex nozzle basically. However, I decided that I would short stroke the gearbox by two teeth and see if that made any difference to the gun; have Dremels, have grinding wheels so, "Why not?". The Murui hop unit is noticeably better quality than the stock one. It all went very well and was back together and ready to rock in just over an hour. Testing was... interesting. It would fire the first shot at around 295 fps and the second at about 195fps. WTF! Anyhoo, for the moment I have given up in disgust. However, some thinking - not something I apply often to airsoft, purchasing or upgrading - makes me wonder if it is the sector clip that is delaying the sealing of the nozzle. Basically, a sector clip will open the nozzle early to allow a bb to feed but by its design it will also slow down the closing so the next step is to get the little bugger out of the sector gear and grind down the closing side - the right hand side when looking down on it fitted to the sector gear.
That's next. Probably tomorrow, or the weekend. Maybe.
