richwuk Posted April 27, 2015 Report Share Posted April 27, 2015 I've checked there the nozzle is released and it's a decent amount down the cylinder and in slow motion appears to have enough time to load a BB. Looking at the nozzle upside down it doesn't look like it has enough time... There is about 2mm movement of the nozzle tip (hop end) in all directions, does that seem a little excessive?

DipTwit Posted April 28, 2015 Report Share Posted April 28, 2015 I don't think it sounds excessive, the piston head does a pretty good job of pulling it back straight, and I'm pretty sure mine are similar to that. Does it feed ok if you just hold the gun upside down and drop a single bb in the tube? Not sure if that's a great test, but curious anyway. Quote Link to post Share on other sites
richwuk Posted May 8, 2015 Report Share Posted May 8, 2015 I brought an Alpha Part Cylinder as I have a nagging feeling about the DTW cylinder (along with the wrong porting hole) and now the nozzle is too short to create an air seal against the hop. The DTW nozzle is slightly too long and I can feel it pushing back on the spring when it meets the hop...new hop I wonder... Anyone have experience of the RWA CNC hop?

DipTwit Posted May 8, 2015 Report Share Posted May 8, 2015 No, but I did try King Arms and one other brand of Cylinder - might have been alpha but I'd have to check - and I did find there are minute differences in nozzle sizing between brands. The diameter, not the length: in some cases, the 'flare' around the nozzle actually binds going into the hopup. So as opposed to not being long enough, it simply doesn't go all the way in because it's sticking. If you have digital calipers you can sometimes gauge if this is the problem, but otherwise you might have to play with it in your hands to kinda 'feel' if this is happening. If so, you might have to carefully file either the flare around the nozzle, or even the hole in the hopup that it slides into. Hope it helps Quote Link to post Share on other sites
richwuk Posted May 8, 2015 Report Share Posted May 8, 2015 (edited) I've just found that the DTW nozzle was starting to work itself loose - it's only a fraction of a mm longer than the DTW one now. I can feel the nozzle being pushed back ever so slightly - not enough if it was fully forward. I assume the nozzle is suppose to help create an air seal like a aeg?

DipTwit Posted May 8, 2015 Report Share Posted May 8, 2015 Yup it sure is. You can double check the chamber packing (that the nozzle seals against) in the hopup to make sure it is in good shape too. Quote Link to post Share on other sites
Cire_ Posted May 28, 2015 Report Share Posted May 28, 2015 (edited) Hey. I've been thinking about buying a ptw clone or a tm next gen. I got an offer on a dtw that has full etiny electrics, new hop up and motor that has some parts replaced and cleaned. If i want to get a G&D Dtw, what parts are needed to be fixed/replaced for it to work good? So far i understood that etiny electrics is a really good upgrade at least. Is the G&D DTW motor any good?

aznsilent Posted June 14, 2015 Report Share Posted June 14, 2015 Wonder if anyone can help me with a internal sector gear problem. So i decided to clean out my gearbox and replaced the eletronics with etiny stuff. When i go semi, i see more than three teeths. If i go burst, i see three then when i shoot again, its more than three teeths. Goes all whiny if i shoot. Not sure if its the motor or the positioning of the sector gear.

DipTwit Posted June 14, 2015 Report Share Posted June 14, 2015 My etiny also lets the sector gear spin just a bit longer / further than standard a&k or systema. This is generally fine as there's no anti-reversal latch so the piston spring tension will keep it from happening when the gun's in normal use. As long as you 'back off' the sector gear to it's typical position (using a burst sounds like it works for you) before you close the receiver shut, it should be all clear. Since your is making weird noises, the electronic swap might mean nothing and you should double check the following (no offense meant if these seem idiotic, people really have done them): 1) motor got installed / wired backwards - easy to check just make sure the sector gear is spinning the right way 2) sector gear in backwards - also pretty easy to check, cuz all the teeth would be on the wrong side. 3) sector gear shim or bevel gear shims in the wrong place - gears might sound ok spinning free but could scrape when under load. 4) motor pinion gear has slipped down the shaft a bit toward the motor. I had this happen to me, you'll see visible wear on the teeth if you do it enough Only things I can think of that would give you those symptoms, hope that helps!

The first and most important thing is to change the hop up, in both, the A&K or the G&D. My motor in the G&D has failed after 18K BBs, but the electronics are still OK. IMO and experience you just need to change the hop up with a Systema one and then replace any part if needed. Quote Link to post Share on other sites
Arbiter Posted July 12, 2015 Report Share Posted July 12, 2015 Just after some confirmation here, am i right in thinking that the newer spec DTW's have mil-spec buffer tubes, mil-spec barrel nuts and will take Systema upper receivers and barrels? Quote Link to post Share on other sites
mcmillan716 Posted July 25, 2015 Report Share Posted July 25, 2015 (edited) I'd like to buy a clone ptw and I was oriented to buy an A&K. What are your opinions about it compared to the other clone brands? Edited July 25, 2015 by mcmillan716 Quote Link to post Share on other sites
Rainer1989 Posted July 25, 2015 Report Share Posted July 25, 2015 I can confirm you that the new DTW can take mil-spec barrel nuts and Systema barrels, no idea of the upper and buffer tube. My G&D motor failed a month ago or so, I have replaced it with the Etiny, the original electronics keep working fine. Quote Link to post Share on other sites
Arbiter Posted August 31, 2015 Report Share Posted August 31, 2015 (edited) This seems the best place to ask this but apologies if it is in the wrong section or has already been discussed, When the receivers are split on my DTW, it is cycling the gears 3 times (as per three round burst) on semi auto. When the receivers are closed, it is only cycling once on semi auto as it should do. I have a set of Etiny electrics in it with the fully automatic function set to three round burst. This is the first time i have noticed this, however it could have been doing it previously and i just have not noticed. I don't cycle my gun with the receivers split on a regular basis Does anyone have any idea what the cause of this could be? Im assuming it will be one of the electronic components rather than something mechanical. Edited August 31, 2015 by Arbiter Quote Link to post Share on other sites
Crying Scum Posted September 5, 2015 Report Share Posted September 5, 2015 I am no super expert myself, but this happens to me when I overexposure the sensor with light. Either in well lit room or directly at the sun, the sensor can't sense the holes, which may cause 3rd burst on semi,. Quote Link to post Share on other sites
Arbiter Posted September 10, 2015 Report Share Posted September 10, 2015 Thanks for the reply. That would make sense. I was outside at the time it was playing up and when i eventually got round to having a look at it, it was completely fine. Quote Link to post Share on other sites
Bastel Posted October 28, 2015 Report Share Posted October 28, 2015 Hi guys, does anybody know if a systema gearbox fits into a DTW Max3 without any problems? Quote Link to post Share on other sites
Erka92 Posted December 26, 2015 Report Share Posted December 26, 2015 Hi there guys! Anyone else having problem with the pinion gear? Have Worn down 2 the last year. Both original a&k. Someone who has a solution? Thanks Quote Link to post Share on other sites
dpvu Posted February 19, 2016 Report Share Posted February 19, 2016 I just got a G&D DTW (Mk18 Mod 1). It seems to be the latest generation, as it has the RWA hop up design but the buffer tube is not silver color. A couple first impressions: -It's solid but noticeably lighter than my PTW Mk18 Mod 1 (Mad Bull licensed rail). Most of the difference appears to be the outer barrel/rail -No wobble in the rail, very solid. More solid than my PTW with Mad Bull rail that I had to shim a bit -The DTW lower will accept both my 2007 and 2012 PTW uppers but the DTW upper will not go on a PTW lower. I suspect the PTW has thicker body pins. I will caliper later to confirm -Cylinders are interchangeable with PTW ones with no problems. Haven't disassembled the DTW one but so far good air seal and consistent FPS -Buffer tube appears AEG spec. My Magpul PTS CTR stock slides on it but I can't get the lock pulled far enough down to actually put it on properly -Solid sound when firing but I haven't done anything other than chrono. It takes all my mags (Systema, Celcius, Rampo PMAG) and bolt stop works as expected. The mag that comes with it is very light compared to a Systema mag 1 Quote Link to post Share on other sites

dpvu Posted January 28, 2017 Report Share Posted January 28, 2017 What pushed you towards the dtw instead of the a&K? To be honest it was that the DTW came in the external configuration I wanted. As it was a backup/loaner gun, I didn't want to fart around with getting a nice rail system on it. For anyone interested, I did caliper the body pins and the DTW ones are about 0.3 mm smaller than the Systema so the DTW lower will take a Systema upper but you cannot put a DTW upper on a Systema lower without boring out the holes on the upper a bit. I have not done this but I'm told it works. Additionally, I had a pinion blow on my PTW and I put the G&D motor and pinion in to replace it and it's performing just fine. RoF is comparable to the stock motor and response is good but not as good as my JG PTW motor. Quote Link to post Share on other sites
thatguy404 Posted July 16, 2020 Report Share Posted July 16, 2020 Old thread I know but...
