You're the best 👌, really saved my ass when a spring came loose inside my gearbox. It's not an easy gun to disassemble. I installed 14:1 specialist arms gearset, high torque motor, maple leaf bucking. Shoots amazing 👏
I really appreciate you doing this for us all, thank you, especially as an owner of multiple DE M900's, as it was to be expected that outside of the externals / changed lower receiver to support the magazine etc. what was inside (the gearbox casing, piston, gears, Falcon controller etc.) would be identical and it is. Personally I prefer their M4/AR M900's, primarily due to their simplicity of construction, but I'd love to see a front wired version however I doubt this would happen as they'd have to tweak the controller and produce a variant of it and that would reduce their margins which I expect are already very slim.
It would be excellent for that, another model with a skeleton stock is coming out soon though too, in case you werent a fan of this type of stock. Pheas
It looks like a Retro Arms split gearbox would be possible to install in this. It seems it has the body pins in the exact same place as an airsoft AR15.
Hey phes i really like your chanel and would ask you to make a review of the r36 gbbr from army armament because there ain't much reviews on RUclips and your opinion is trustworthy thank you for the awesome content. Love from Bulgaria.
Great video, saved me quite a few work, just got this made some upgrades but could not get a new motor (guarder high speed) in the original has a bigger pinion head and the reshiming did not work (keeps scratching), have you come across something like that before?
Hello thank you for your vidéo ! I have tried to change my joint by a mapple leaf 50. When i rebuilt the replica my utr doesnt feed… i dont understand… could you help me ? :)
Sir thank you for these vids, I am trying to find a nice body to drop my polar jack into , do you know any easy body to drop in a v2 gear box perfer metal body with functional bolt catch to adjust hop up
Hello, thank you very much about this guide! I'm currently having an issue trying to take apart the gearbox on this replica. Unfortunately I seem to have stripped one of the trigger selector tiny grub screws (13:08) and likely the long one holding the left bolt release button (11:50). Do you happen to know the specs of these screws so I can search for fitting replacements ? You do mention that it is a "1.3 mm (?)" allen key so I suppose this is the measurement to use for finding replacement screws ? As far as I know DE does not seem to provide replacement parts/screw sets despite the quite unconventional and proprietary set up of this gun... Thank you in advance !
Hiya. I don't know the exacts... But if you but a set of grub screws with a selection of sizes you should be ok. If the 1.3 but doesn't work because it's rounded... Try using a small torx but, like a size 6 or smaller as this often grab when the 1.3 hex heads are rounding out. I tend to, where I can, use the small torx bits as they grab better and tend to not have the rounding issues. Hope that helps. Pheas
@@PheasAirsoft Thank you, I used a small torx indeed, (i think it was a 1.5) and it worked after some effort. I had to punch it in so it bites onto the screw and keep applying pressure while turning it but eventually it worked! After some testing it seems that the threads on the selector itself were a bit tight making it hard to unscrew and easy to mess up the screw with the wrong allen size. Again thanks for the help, I will keep following your guide now that I can access the gearbox!
Hello! I will need to find somewhere else to source it from, but will add it to my list to get thanks (Shame TG not shipping to uk, looking likley never to again) Pheas
I’m thinking of getting one but don’t know to choose between the 350fps or the 400 at my field it’s a 400 cap for rifle man and it’s out doors I use .28 gram bbs
I would go the 400, it shouldn't be any more than that. That said.... Fps Is only how fast your bb gets to it's destination. The hop rubber and barrel are the range and accuracy. Pheas
I couldn't for the life of me tell you their outside size, but if you want bit size, then they tend to be either T5 or T6 (Torx) bits needed for them. Pheas
Hey I could use some help! Mine stopped working a week after I bought it. Battery is full charge it’s giving me the 5 buzz low voltage notice. I was kinda sending it hard with binary when it stopped. The motor was pretty hot. But it will shoot a few rounds after I unplug and plug in the battery. Any help from people on here would be appreciated.
@@calculatedchaos9134 hello. First think I would try is another battery as the one you have might be not balanced, or the cells could be damaged. Next I would try and swap motors out and see if changing the motor has any impact. Pheas
Hey, im a complete noob in airsoft, to change the bucking, i have to dissasembly the outer barrel like you explained in the beggining of the video, right?
Hiya, nope, just take the upper off, and pull the barrel and hop assembly out from there. Then it slides back in again when you are done! The top goes back on again and you are all sorted! Pheas
Hello! 1. Yes it is an outstanding beginners gun, 2. Excellent out of the box, needs nothing doing to it, 3. Yes it has an M4 type (Version 2) gearbox. Pheas
Fuck me - this looks unreasonably good value. Rotary hop, interesting rubber design, decent air seal, Deans… the MOSFET durability and quality of shimming are the only outstanding questions I have.
The shimming is very very good out of the bed! The mosfet in the older models seem to have some issues, but not heard anyting bad at all about the newer UTR and UTG models mosfets! Pheas
Does it have a standard M4 hopup chamber? It looks like it does. If it is, that's a great HPA base gun, affordable and at least it's not another HPA M4.
Hiya! With springs, depends on the fps you want, a 100 rated spring should give around 330fps or there abouts, ahnd then jump in about 30 to 50 increments as you go up through 110 and so on. As for rubber.... Maple Leaf MR 2021 rubber and if it will fit, the omega nub to go with it. Pheas
@@PheasAirsoft Wow thanks for such a quick reply! I just bought one of these and I love it but the range was a little poor , Unsure if i am expecting too much from an SMG compared to my M4 as ive not owned an SMG before. I want to hit near to 315 on .25 bbs. I figure the best bet would be spring, hop rubber and new nub. Do you know what spring is in there out of the box?. Have you upgraded one of these yourself yet?
@@Lowe2476 I think the factory stock spring is between m110 to m120. So you might need to drop the spring out for something around the m110 (proper one) to get those sort of FPS, but... I would do the barrel and rubber first, to get your seal sorted, then mess with the spring to match it. I have done a barrel change as requested on this one before it went to its new home! Pheas
@@Lowe2476 Got very very good results from it, cant remember the specific barrel as he sent it to me, possibly zci tight bore, with the MR rubber and was excellent! Pheas
How are your shimmings set up? I took mine apart in the hopes of making it shoot faster, but I think I screwed up, but now I dont know how many shimmings go on each gear! please answer my gun is just sitting here waiting to be fixed
Hello! the number could be different even two identical guns due to tolerances between them. The main thing to remember is to make sure that when they are all in, there should be the minimum possible movement on their axels whilst still allowing very easy free movement. If you remove the cylinder and screw the gearbox case shut then you should be able to spin the sector gear and it should spin 3 times to show if its freely moving. IF you wanted more rounds per second then consider an uprated motor instead. Pheas
@@PheasAirsoft Thanks for the reply, I managed to put it all back properly and it works perfectly fine. Whats an uprated motor? I have a spare G&G Combat Machine CM16 SRXL motor, but i don't know how to tell if its better than the stock one in the utr. Any advice would be much appreciated
@@dirkthechimp746 I don't know the rating for the standard one, but if you Google the name of the motor and "tpa rating" with it it should give you a number (like 24 tpa) the higher the tpa number the more torque (fast the motor can get to speed) so ideally look for something with a higher TPA than the stock one. If you aren't having luck finding the info, then just swap the motor over and see how it feels sounds as that's as good a way as any! Pheas
Most of them faded.... or gor mysteriously ruined in a freak decoating accident.... whilst my wife was using them to decorate in.... How unusal... even more so considering she didnt like them. But glad you liked the video!! Pheas
Thank you for doing this video! Was considering getting this beautiful piece and still on deciding! Too bad it still uses v2 design. Was hoping it would use v3 so it's less of a pain to set the alignment of motor and gears. Still, a beautiful replica! Edit : Do you happens to test what other mags it could use?
Great to hear there are some mags it would be compatible! Though it's g&g prop mags ahaha, was hoping it would use matrix ump45 mags. About the gearbox, is it proprietary or some other v2 gearboxes would work?

Hi, I just ordered an UTR45 and I have some questions about the battery and the mosfet. 1. Battery On taiwangun it is stated the following: "The recommended battery with the highest safe voltage for this replica is -11.1V. If you decide to reduce the power, be sure to not use batteries with a too high voltage - 9.6V NiMH is recommended, and in the case of Li-Po / Li-Ion - 7.4V" - Taiwangun recommends IP-LIPO-007-TC. I ordered a Li-Po 11.1V battery but with 2200mah (BATTERY LI-PO 2200MAH 11,1V 20C - DEANS [IPOWER] ) - same specifications as taiwangun recommends (IP-LIPO-007-TC), but just more mah. Is the battery going to cause any issues? If yes, why and what battery should I replace with? 2. Mosfet Does the replica come's with a mosfet from the factory? If yes, is the factory mosfet enough or does it need to be replaced? Thanks!
Hello! The battery will be absolutely fine for this. The MOSFET included is excellent, there are very few instances of it failing, it's very robust. However if you do find that it fails then a Perun v2 hybrid would be an excellent replacement for it! Pheas
That is a very tough choice. Because I love an SMG type... I would choose this, but internally they are virtually identical. The one thing back the other way, in favour of the m90x series... M4 mags are easy to get! That said... Would still be the UTR45 for me. Pheas
Silly question, but is the hop-unit in this gun proprietary? It looks similar to and M4 rotary unit but I'd want to make sure before purchasing this gun
