harborne blue Posted May 12, 2009 Report Share Posted May 12, 2009 Apologies for thickness but I am still a little confused. Is th correct for the ACM M14s then: Two RED wires soldered to upper trigger contact - one goes to the motor, one to the battery One GREEN wire soldered to the lower trigger contact One BLACK wire straight to the motor from the battery And no other wiring needed for the FET to work e.g. I don't need a section of green wire linking the trigger to the right side of the gear box. I'm pretty comfortable around M14s and picked this one to FET first as, given the external trigger contacts I assued that I wouldn't need to crack open the gear box. Link to post Share on other sites
chownsy Posted May 12, 2009 Report Share Posted May 12, 2009 Infected AGM M14s dont have anythink like that picture. My agm M14 has no safety contact it jsut has positive to trigger contact, to motor then negative to battery Link to post Share on other sites
mike174 Posted May 12, 2009 Report Share Posted May 12, 2009 Hi looking at building a few AB mosfets but don't really have a clue what parts are correct. I've read the whole thread and the airsoft retreat link but i'm still not sure exactly which parts I need I no I need an N and a P mosfet and a 20k ohm resistor and a 100ohm resistor but I don't know which ones are the best ones to get. If any one could provide the part numbers or links to the parts i need it would be great and also is RS the best place to get the bits or is there some where better? Any help would be great Cheers Mike Link to post Share on other sites

My agm M14 has no safety contact it jsut has positive to trigger contact, to motor then negative to battery Then it should just work like a v2 gearbox as far as the wiring goes. I believe only TM is crazy enough to put all the wiring they do on an m14. Link to post Share on other sites
M4_Fanatic Posted May 12, 2009 Report Share Posted May 12, 2009 Sorry if this has been asked before but has anyone tried using the AWS Airsoft MOSFET with an L85 (specifically the "Scorpion HRC-X340 w/ Sensor Hopup")? I might be interested in getting one even just for the sake of the built in tracer and the realistic anti-dryfire system... Link to post Share on other sites

mike174 Posted May 16, 2009 Report Share Posted May 16, 2009 thanks for the reply Greg thats great help only thing i need now is someone to recommend a p mosfet from rs and im sorted Mike Link to post Share on other sites
crackisbad Posted May 20, 2009 Author Report Share Posted May 20, 2009 picked up a couple fets from AWS while they had them in stock for about 4.62 seconds. Top one is their "micro," which is about the size of infected's regular fet, and bottom is the Sentry: will let you guys know who they hold up once I install them. Link to post Share on other sites
harborne blue Posted May 25, 2009 Report Share Posted May 25, 2009 HELP! Just fitted a FET (Infected) to my AGM M14... The motor spins beautifully but the gears don't spin when it's connected back up. The gun just gives a 'click' when I pull the trigger! It was firing fine before I fitted the fet and all I have done to the gun itself is to solder the fet in place. I also tried spinning the gear I can see (when the motor is off) by hand and it doesn't seem to move. What's gone wrong? Link to post Share on other sites

mike174 Posted June 9, 2009 Report Share Posted June 9, 2009 Did you read post no99 and follow the link? I did i have read the whole thread but i had no idea if i wa looking at the right quality/ capacity parts as there are a lot of different parts on rs and i have no idea about components only electronics i have done is rewiring a gun or changing a fuse.

Clot Posted June 10, 2009 Report Share Posted June 10, 2009 Holy moly those irl 1404's are expensive, though their stock levels are great! I get em from RS, though half that price, they take over a week to get. Try this http://uk.rs-online.com/web/search/searchB...amp;x=0&y=0 Link to post Share on other sites
LordElpus Posted June 10, 2009 Report Share Posted June 10, 2009 i do have some ir1404s in a antistatic bag somewhere if anyone want them PM me and we discuss it there. In other news, just finished wiring up one of Infected's AB mosfet units in a UMP. dear lord there is not much space to put anything in that body. Link to post Share on other sites

If you stick one of those firefox 11.1v lipos in there there's tons of room for one of Infected's MOSFET's. That's how it is with my G&G at least. Link to post Share on other sites
wolfesbane Posted June 13, 2009 Report Share Posted June 13, 2009 Hi there infected thanks to ur great lipo thread i have 2 on the way 7.4v 2800mah which u have already helped with in the thread with regards to AOE ect one is going in my A&K M249 so my questin is what sort of mosfet would be best for me and would the standard wiring stand up to the power supply ect as not all A&K wiring is the best from what i hear Thanks for the help Link to post Share on other sites

I have one, so I know. You can put 16 gauge wire in there easily. My mosfets will work great in that gun, just make sure you're shimming is spot on as the stock shimming is horrible.

Bersy Posted June 16, 2009 Report Share Posted June 16, 2009 Made my first mosfet today! i used Doubletap's guide only thing is the motor gets hot tho! but its a ACM kalash motor so i dont expect much from it! Link to post Share on other sites

Your motor really shouldn't get too hot unless you're firing a bunch of rounds, using a high voltage batterypack, or laying heavy on the trigger. Link to post Share on other sites

Yea i might shim the bevel gear abit more to the right but it was a pain in the *albartroth* getting a pdi 130 in there! Link to post Share on other sites
jackypoo Posted June 26, 2009 Report Share Posted June 26, 2009 Hi there guys! This is my first post on this forum, been a fan of the site for a few years now, and just had a few questions about the MOSFET + AB; First off, does Doubletap's guide to building the AB-MOSFET result in a pretty generic AB-MOSFET; i.e. Does every AB-MOSFET have that same design? If that is the case, does the rest state of the system draw noticeable current? I'm just asking because after failing to comprehend how it works, I modelled it on croc clips just to see what happens. It ended in about ~200pA drawn through a 200W lamp (No motor available in the software). I know its not noticeable current, but after a while it will add up. The lamp was an estimate too, I tried a signal lamp but it seemed the resistance was too high. If you like, I can post the pics, but maybe it is just the software being a fool Link to post Share on other sites
