thatguy404 Posted November 8, 2013 Report Share Posted November 8, 2013 Update:Took apart the CQB PTW 2012 hop, as wasn't feeding no matter what.Here we go.The hop chamber sleeve on the DTW, is smaller than the chamber sleeve on the PTW.So to use the PTW barrel, I had to use the PTW sleeve.The DTW hop adjuster is actually larger than the PTW (at least on my DTW)So I am using the DTW hop adjuster + packing, on a PTW barrel with PTW chamber sleeve.But it all fits inside the DTW hop chamber base. FPS is again around the same, and I cannot range/accuracy test until next week. Quote Link to post Share on other sites

I thought that the barrel diameter (and the chamber) were redesigned to be 100% compatible with the MAX3, is it not the case? Quote Link to post Share on other sites
Isamu Posted November 9, 2013 Report Share Posted November 9, 2013 (edited) More Rotatory hop ups http://www.ptwcustom.com/index.php?main_page=product_info&cPath=169_231&products_id=568 EDIT: About hop compatibility, yes, MAX3 chambers are said to be redesigned to be 100% comatible with Systema ones, how tru is that?, I dont know, I plan on using mine and not a systema. In the events I decide to upgrade my chamber, I will be doing it from a rotatory option or the AEG barrel chamber Edited November 9, 2013 by Isamu Quote Link to post Share on other sites
thatguy404 Posted November 9, 2013 Report Share Posted November 9, 2013 Mine cannot be a Max3 Model.But at least I've made some progress.I'm curious to if the hop packing will work on the barrel though. Just gotta test it.I've attempted to make the PTW hop chamber sleeve to feed. Itself to no avail with plenty of filing and sanding. Quote Link to post Share on other sites
Stan-O Posted November 10, 2013 Report Share Posted November 10, 2013 I could have saved you the trouble if you asked. BTW, I've ordered the complete "G&D DTW" hopup chamber from rsov before the MAX3 were introduced and the sleeve was out of spec -- it's too large for the 1st gen DTW barrel and too small for the PTW barrel. Just so you know if you decide to get one too. Quote Link to post Share on other sites
thatguy404 Posted November 10, 2013 Report Share Posted November 10, 2013 Haha, cheers stano. I've read your review so many times I don't care to count anymore. Thought I'd get a systema hop and try it for myself. Any idea which part causes it to foul in the dtw? The fit seems perfect, it feeds but fps I crazy low, and it makes a metallic noise when firing Quote Link to post Share on other sites
LordElpus Posted November 10, 2013 Report Share Posted November 10, 2013 i had that in my dtw. FPS was around 230ish. the same cylinder in another gun was 340fps Quote Link to post Share on other sites
Isamu Posted November 10, 2013 Report Share Posted November 10, 2013 Did you manage to solve it? Quote Link to post Share on other sites
thatguy404 Posted November 10, 2013 Report Share Posted November 10, 2013 Mine must be a fit issue with the ptw hop chamber, I'll get some calipers on it and find the issue. I'm using the ptw barrel, abd chamber sleeve, with dtw hop packing. So it must be the chamber dimensions Quote Link to post Share on other sites
LordElpus Posted November 10, 2013 Report Share Posted November 10, 2013 lol, mine was with the stock hop/barrel combo. No Isamu, not got around to fixing it yet. Quote Link to post Share on other sites

The fit seems perfect, it feeds but fps I crazy low, and it makes a metallic noise when firing Sorry I can't help you there, my buddy has his version of the PTW hopup mod so the hybrid (PTW barrel and sleeve + DTW rest of the hopup chamber) barrel he's built while I was away and which I've tried in the 1st gen DTW didn't have any feeding or performance issues with about half a mag I've shot into a box at home (to chrono the cylinder). I can be wrong about it, but I think I've also tried the AiroTW barrel assembly in my 1st gen DTW without any adverse effect on FPS either. Speaking of metallic noise -- any traces of contact on any metal surfaces? Quote Link to post Share on other sites
thatguy404 Posted November 11, 2013 Report Share Posted November 11, 2013 I've built the same combo myself.Did he have any accuracy issues or anything like that?I'm yet to be able to test mine. No traces of contact, it's when the gun isn't feeding correctly, it'll still fire a BB, but the FPS is lower, like a metallic clang instead of the zip/pfft noise they usually make.

Stan-O Posted November 14, 2013 Report Share Posted November 14, 2013 A little update on my AiroTW. Just like Ben from Asiarsoft promised I've received the new mini-FET for my AiroTW earlier today. It's been a while since I've assembled PTW so it took me some time to replace the FET, but now I can fit 11.1V LiPo in the buffer tube and run with either CTR or STR. I hope to get out this weekend to actually field it, and quit chairsofting. Quote Link to post Share on other sites
Isamu Posted November 15, 2013 Report Share Posted November 15, 2013 Just a little update on the spares I got yesterday. The Action steel boltcatch fits OK and is shaped like the Max3 one. A longuer and stiffer spring comes bundled with the part, which I installed right away since the spring in the DTW is a bit suitcasey. Will test it along the weekend (bit occupied right now) Action barrel keys are a godsend for us who like tinkering with the hop up chamber, the provided screw lets us install and remove it efortlessly, they are 5$ per 3 pieces and even as I dont know what are they made of, they feel great. They are a bit loose in the MAX3 chamber though, nothing a bit of tape wont fix Now, just a question, the grub used to adjust the hop chamber gives me the creeps, to be honest, im a bit afraid of loosing or damaging the hex hole. I measured it to be 3.5mm wide to try finding some cheap replacements to no luck. Anybody knows a place to buy them? Quote Link to post Share on other sites
Isamu Posted November 17, 2013 Report Share Posted November 17, 2013 Moar updates, please forgive the double post. Fitted an M95 spring in the cilinder without further mods to it, using the stock cleaned barrel, 0.20gs, no hop, im getting 345 to 355fps, expected something closer to 330FPS @_@ Managed to get some second hand vanaras mags and they fit into the Max3, a bit snuggly but a tactical hit to the bottom will make it click in place perfectly. Removal requires to extract the mag, it wont fall by itself. Good news is that there is absolutly no wobble Bad news for me is that the action boltcatch wont be activated neither by the vanaras or the stock DTW mag, I have reinstalled the stock boltcatch until I manage to make itwork... somehow More bad news is that my first attempt to flat hop it has failed misserably FPS variation was too high, back to drawing desk...

thatguy404 Posted November 17, 2013 Report Share Posted November 17, 2013 Do the vanaras magazines work well with the stock bolt catch? Do they struggle to click in because of the mag body, or the window on the magazine where the release catches it Quote Link to post Share on other sites
Isamu Posted November 17, 2013 Report Share Posted November 17, 2013 They do work right with the stock boltcatch The fitting "issue" seems to be due to the mag body being a bit widder than the magwell, or the magwell being a bit narrow, depends on how and who looks to it, but once convinced to fit, the magcath works properly fine Quote Link to post Share on other sites

LordElpus Posted November 17, 2013 Report Share Posted November 17, 2013 News from my gen 1 dtw.. The installation of a 2012 Systema hop and inner barrel has upped the fps from 240ish (big ish..) to 312fps give or take 2fps. There appears to be some play in the cylinder when fired so hopefully the installation of a shim or 2 to the the buffer tube endcap (or whatever the disc with 2 o rings is called behind the cylinder should stop the cylinder from jumping and sort the final air leak. Now i just need to wait for the mosfet to burn out like everyone elses Quote Link to post Share on other sites

thatguy404 Posted November 17, 2013 Report Share Posted November 17, 2013 If I'm honest baz, the rifle on it's owned out performed all my g&g rifles. However since I've upgraded them I'm used to a certain standard and want to get the dtw to the same spec, the only place (for me)it is lacking was the accuracy. But I suppose it'll never be as good as a real sword from pas.. Quote Link to post Share on other sites
Baddbaz Posted November 17, 2013 Report Share Posted November 17, 2013 (edited) Once you get used to a particular standard from your kit it gets expensive . , I have learned this from every hobby I have participated in Nowadays I try to buy guns that I know I can get some return on should I decide to up sticks and sell up .

Stan-O Posted November 22, 2013 Report Share Posted November 22, 2013 (edited) ######, Airo's mini mosfet is selling for $45.99 at ehobbyasia now, I was hoping to unload my old "big-stick" one for about as much. Edited November 22, 2013 by Stan-O 1 Quote Link to post Share on other sites
