Connorthescot

Hey folks, Thanks @Airsoft World/ @airsoftworldfor spotlighting the issue! Having had a LEVAR in bits today to source the location of a gas leak, and then spotting the post on Facebook - I am curious if this is a pressure issue whereby the stresses on the pistol grip does cause the single bolt to loosen, making the seal to the inlet nozzle at the top of the grip to loose its seating. Without that seal and correct seating of the gas inlet nozzle, is there a possibility for gas to migrate into the cavity between the metal gas chamber and the plastic outer grip case - I cant imagine that tiny volume handling 120+ PSI! Best of luck with the issues, and hopefully G&G issue some guidance soon!

Thanks very much for the quick response - I am not even sure how he managed to reverse polarity with the mini tamiya connector. Must have tried very hard to get those connected! Do Marui offer any sort of factory repair service for these occasions? I will need to see what he wants to do with it considering it has never been fielded and literally in his possession for only a few days before it went kaput!

Hi folks, Working on a Tokyo Marui MP5SD6 NGRS for a friend. Unfortunately, after trying a new battery in his replica, the mini tamiya shorted / melted on the positive pole of the connector. After changing out the tamiya connector with a deans, the etu is giving me a double red flash. I am trying to diagnose what on earth he has done here but quite honestly my biggest struggle right now is removing the damned fire selector. Looking at some videos, it seems to need to be in the fourth position pointed towards the rear of the gun, then whilst depressing the trigger it should be able to pull out. I cannot for the life of me get this thing to budge, there is some separation from the lower but no amount of prying seems to want to get this thing to move. Is there a knack that I am missing here?

Reporting back, and thankfully the firehawk has come back to life! So bottom line is that the trigger contacts were 1) a little grubby and needed a clean and 2) the actually positioning of the trigger contacts was a bit off so contact was not being made consistantly. Thankfully, managed to get everything back together again and she is shooting great - so far! Game day on Sunday so will take this a long to see how it gets on. Thanks for the help all!

Photo below for reference, it looks as if someone has been in here before and tried giving that contact a scrape but yeah thats the contact I am concerned about. No carbon or black buildup immediately visible though but I think I will take the whole mechanism out for inspection.

Morning all! @Floperator - Thoughts and prayers definitely needed, managed to get the box open without it blasting everywhere with that damn spring ? So the contact on the trigger switch / shuttle (not exactly sure what the name is) is tinged orange / red. I could not find a good reference online for a 'burnt' contact but judging by the colour of the other contacts then this does not look right. I might connect up the battery again and test voltage pass through up to the contacts, then make contact with the trigger and see if I am getting anything from the bad looking contact. @Fatboy40 - That might be a good shout and a very generous offer! Shall I PM you and we can arrange that? At this point, I am thinking that dropping in the other gearbox is easiest considering this is a hand me down firehawk.

So motor definitely works, direct battery to motor and it spun no issues. Looks like a gearbox is being opened tonight - god give me strength! ?

I would love to pop in a GATE Titan or any mosfet into any of my systems but yet to dabble in it. Next time though @Fatboy40! Really just need to get this AEG working, messing about with it for ages. I think I can jimmy rig some wires to test direct from battery to motor tonight, atleast that rules out the motor and then it comes down to any wiring issues in the gearbox and trigger contacts. Tried a continuity check again a minute ago and I am getting nothing when testing the positive cables with the trigger pulled.

@Floperator - I managed to get the wires swapped around all good, unfortunately still no luck getting this motor turned over

Thanks for all the responses so far, really appreciate it! So with the polarity of the tamiya connector changes so the negative and positive is consistant, I am still getting nothing from the motor. The fuse looks to still be intact too which was a suggestion from discord that trying to run the motor without the wires on the tamiya changes may have blown the fuse. My gut feel is that I am now going to need to open up the box, first time for everything I suppose ?

@strykerles - I just noticed that too actually.. is there any way to remedy this apart from fitting a brand new tamiya connector? Sorry, double replies there - browser was being wierd! Yes, unfortunately I think that is exactly the issue and yep it was from eBay! Reading quickly, looks like this is more for an RC setup and not airsoft. Let me give it a bash mate and see how I get on, thanks for the assistance so far! Managed to re-wire that tamiya connector to keep positive and negative the same throughout but still unfortunately getting nothing. Heading out shortly so will try again in a bit.

@Shamal - Motor connections physically look and feel okay. The connection from the lower gearbox onto the motors may be slightly on the looser side of things but still fit snug onto the positive and negatives of the motor. @strykerles - Yeah, fuse is still in tact after it spun. When it did spin, I was moving the selector plate with my hand to see if I could engage the trigger contacts and connection must have been made somewhere. It was only a single very short spin, as it it was semi-auto. Also, just for reference I have attached an image. If you need any other images to assist do just let me know. [EDIT] Looking at the photo below, I have actually just noticed a possible issue. The positive and negative wires flip from the tamiya connectors i.e. red (positive) from battery then goes into black (negative) from the back of the wiring harness. Could that be the issue? Thanks,

Hi all, So I have had a G&G Firehawk passed on to me from a friend and unfortunately straight away I have ran into an issue. Initially I hooked up a 1300 mAh 7.4v 20C LIPO and was getting zero trigger response on either full auto or semi. Double checked that the battery was charged using a mutlimeter, and it was. I then moved to the rear wiring loom going from the butstock out to the tamiya battery connector, the fuse connection looked slightly off so I have replaced this wiring and fuse. Tried again with the battery and still nothing. I have now taken the gearbox out of the lower and tried connecting the motor and battery up, and oddly I have had the motor function only once, which scared the crap out of me as I was just expecting it not to work. So I have had a single rotation of the motor on semi and I cannot replicate that at all unfortunately. I am thinking my next step is to open up the gearbox and check trigger contacts but I just want to get any advice before I go ahead and open this up. Thanks,
