joseph1975 Posted December 19, 2012 Report Share Posted December 19, 2012 Is there a guide to install this? I am clueless.. I'm not sure if there's any. I just figured all this on my own. If you're planning on buying one of these switches, just cut the tabs to the desired length. Quote Link to post Share on other sites
ljparton Posted December 22, 2012 Report Share Posted December 22, 2012 I just did this to my PTS Masada after running 1000 rounds through it at 380 fps and 23bps, I was planning to sorbo and radius but this happened first. Anyone know where to get just a Masada gearbox shell? I am located in the US by the way. I saw that Aztec Reinforced Mechbox for the Masada but I think it's a bit overpriced, no? 1 Quote Link to post Share on other sites

ljparton Posted December 24, 2012 Report Share Posted December 24, 2012 Try this one: http://www.fire-support.co.uk/product/magpul-pts-acr-parts-msd-gear-box-case After the horrible exchange rate, and shipping it'll cost me almost 90 USD to get it here. I may as well get the complete GB for 118 on Ehobby, and give the spare parts and motor away haha. Or, maybe I'll get the Aztec Reinforced Mechbox but that isn't even out yet. Lyng's Mechbox used 9mm bearings which I find strange. Quote Link to post Share on other sites
lacanuck24 Posted January 21, 2013 Report Share Posted January 21, 2013 Call me lazy cause there are just way too many pages and I'm a combination busy and lazy. I burned a piston last weekend and need to replace it. My problem is I forgot which version piston to get. I remember hearing a regular version 2 won't fit, could someone please tell me which version piston I need to use? I've been looking at the Deepfire titanium that lot of people have been mentioning, but just want to make sure I get the right one. Thanks! Quote Link to post Share on other sites
Seraph01 Posted January 21, 2013 Report Share Posted January 21, 2013 Im using a Guarder Poly Ver 2 and its working great, my brother is using a Ver 2 SHS Poly. Some Ver 2 will work but not all. I know the System Ver 2 Polycar wont work cause of its octagonal edges, they rub the wall of the gearbox Quote Link to post Share on other sites

joseph1975 Posted January 24, 2013 Report Share Posted January 24, 2013 Um, does anybody here knows how to modify the KWA K120 to feed properly? I can only use it on semi-fire. My gun runs @ 28rps. Thanks. Quote Link to post Share on other sites
Seraph01 Posted January 26, 2013 Report Share Posted January 26, 2013 I believe the spring strength on the KWA mags isn't as strong as the PTS mags. Others shooting above 25rps were also having trouble on full auto. Quote Link to post Share on other sites
joseph1975 Posted January 26, 2013 Report Share Posted January 26, 2013 Thanks. Yeah, I posted this as well on PTS Masada group on FB and we arrived at the same conclusion. I solved the problem by switching from 11.1 to 7.4 and now I'm able to use the mag. I wonder if there's a stronger spring that I can put in. Quote Link to post Share on other sites
Probotector Posted January 27, 2013 Report Share Posted January 27, 2013 Thanks. Yeah, I posted this as well on PTS Masada group on FB and we arrived at the same conclusion. I solved the problem by switching from 11.1 to 7.4 and now I'm able to use the mag. I wonder if there's a stronger spring that I can put in. You could also install a Delayer Clip onto your Sector Gear so that the nozzle stays longer to the back, giving the magzine more time to push the BB into the chamber. Of course this could lead to loss in FPS if not done carefully. Quote Link to post Share on other sites
ariamark Posted January 29, 2013 Report Share Posted January 29, 2013 I dont know that one, but important question is does it fit as a drop in for Masada gearbox(v2-3)? do Masadas have different gearbox's then ? i dont acualy own one but 4 of my friends do Quote Link to post Share on other sites

speculator Posted February 1, 2013 Report Share Posted February 1, 2013 Was wondering if anyone ever ran into this problem. The piston of course broke on my stock gearbox so i went ahead and replaced it with this (everything is left stock): http://www.ebay.com/itm/181047049415?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 However, when i fire the gun, it struggles to fire and the battery, wire and motor starts to heat up. Eventually the gun would slow to a halt and stop firing. Anyone know what the problem might be? Quote Link to post Share on other sites
joseph1975 Posted February 1, 2013 Report Share Posted February 1, 2013 You have to remember this gearbox is not standard, so not everything will fit in. It might be the piston is too big. I have an SHS 15 teeth in mine and it's been great so far. Quote Link to post Share on other sites

speculator Posted February 1, 2013 Report Share Posted February 1, 2013 (edited) Ah, do you happen to have a link to which one you purchased? (Also, does anyone have any measurements of their piston?) Edited February 1, 2013 by speculator Quote Link to post Share on other sites
