Hedganian Posted April 29, 2009 Report Share Posted April 29, 2009 From Infected in the US - everyone agrees that his are awesome. Or from Doc in the UK - he put one in my G36 while he was overhauling the gearbox, and it works fine, no issues. Doc's are more basic, though, I don't think you'll get 3-round burst from his. He might be able to do it, though - drop him a PM if you want. Link to post Share on other sites
greg Posted April 29, 2009 Report Share Posted April 29, 2009 Back to my original point - where can I buy a MOSFET If you just want a simple mosfet & can solder, you could follow the instructions to make the 'project airies' fet as described in Airsoft International Vol4 issue 6, pg40/1. Relatively cheap & simple to do. Re purchasing fets, Infected's fets are great. He does a full range of fets, ab fets etc. If you ask nicely, for a small charge he will even supply them with specified lengths of wire, which makes replacing your loom easy peasy. I have used about 20 of his ab mosfets in the past few years. I have crushed a few, trying to squeeze them into small guns, but other than self inflicted damage, none have yet failed. His product (including the wire) is well thought out, top quality, & reasonably priced. Normally gets to the UK within about 11 days. I would definitely recommend you contact him & place an order.

infected Posted April 29, 2009 Report Share Posted April 29, 2009 Thanks Greg! Also to clarify. MOSFETs alone DO NOT do 3 round burst. To do 3 round burst you have to have a micro controller. Without a micro controller, they have no way of handling the timing. I do not currently provide microcontrolled units yet. Also note that in some setups 3 round burst mode is really an average. if you change batteries, or the battery voltage sags, you'll see inconsistencies in 3 round burts. The units that have these features have gotten better over time, but be aware they are larger so fitting them in tight places can be difficult. Link to post Share on other sites
greg Posted April 29, 2009 Report Share Posted April 29, 2009 Thanks Greg! Your welcome, I'm only calling it how I see it. I see your product & service as good, it is only fair that I suggest others give it a go. Greg. Link to post Share on other sites
crackisbad Posted April 29, 2009 Author Report Share Posted April 29, 2009 Back to my original point - where can I buy a MOSFET Sometimes, I wonder why I even bother From the very first post of the thread: .... For those of you just looking for where to buy Mosfets from: Our very own, Infected: Infected Airsoft AWS Airsoft Extreme Fire Unconventional Airsoft HH Airsoft list will be updated periodically The Extreme Fire and Unconventional Airsoft website sell microcontrolled mosfets so that you can do 1-8(adjustable) round burst. As infected said, it is only a timing system that you adjust for the setup you have, so the burst might be inconsistant. The AWS website has microcontrolled fets as well but the ones with burst options are sold out. For just a regular non-burst fet, I too would recommend Infected's; really great stuff.

Hedganian Posted April 29, 2009 Report Share Posted April 29, 2009 Do you really expect people to go back and read the first post in a 130+ post thread? You should know better than that.... I have the same thing in the AUG FAQ thread - that is assuming people find the thread at all, they don't check what's already been asked and answered before asking. I assume it's because people click the "last post" link rather than the post link, which takes them to the end of the thread rather than the beginning.... Link to post Share on other sites
Lon Posted April 29, 2009 Report Share Posted April 29, 2009 Just got one of infected's MOSFETS. Can't wait to drop it into my G36. I've had numerous issues with switches burning out easy (specially with higher voltage batts), so I hope this'll help. Also hope that I won't *fruitcage* up the install Link to post Share on other sites

Lon, like greg said, it should be cake; very simple soldering. I just bought a couple fets from AWS, I will post some pics and info when they come in. Link to post Share on other sites
harborne blue Posted April 30, 2009 Report Share Posted April 30, 2009 I've got two on the way from Infected One's going into an AGM M14 - should mean that the trigger and cut-off lever take less of a bashing. One's going into a KA FN FAL - should fix the dodgy semi auto that's been giving me gip. I haven't soldered anything for a few years so I'll practice first! Link to post Share on other sites

chownsy Posted May 9, 2009 Report Share Posted May 9, 2009 HELPPPP!!!! this thread helped me but im still confused. so have a few questions dads and electrician so sourcing the parts is easy and cheap. wiring them together also easy. i want to build an active breaking mosfet for a few rifles. M14 (semi only) 8.4v 3700 MaH battery (m120 spring) M4 (semi and auto) rear wired, 8.4v 3700MaH battery. (M100 spring) and a few others all on simular set up these are all my own rifles. basically questions are 1. will these mosfets cope or do i need higher quality ones (p channel) SPP80P06P made by INFINEON and a (n channel) IRL3713P - Unknown make BF-ND?? 2. the 20k Ohm resistor i read is too high is this true (pull down resistor??) 3. Whats the wattage of the 2 resistors i need. 100 ohm ?? W and 20k?? ??W could someone supply correct part numbers (im currently using the RS book and the N channel mosfet is not a held in stock item) also when wiring into the gun, i get confused with where the trigger contacts wire to, and where the battery - motor wires to. (just from reading as i dont have a mosfet to hand) If someone has a wiring schematic it would be helpful. have looked on the Airsoft retreat link which helped a little.

The MOS is one of yours with AB Here's the TM M14 wiring diagram (looking down from above on the gun). The CYMA is a bit more straight forward, as there isn't any wiring on the right side of the gun.
