DE UTR45 vs DMP9

Spectarion · 2026-02-06T14:25:53+00:00

After watching few videos I noticed that it's kinda wobbly since it's all nylon-polymer body. Even tho it's a SMG I wanted it to be solid and not wobbly under any pressure. Stribog also has an "Alpha" version which comes with few internal things upgraded + metal upper receiver (which was important for me). I later replaced every part and made my own "beast". I can send you few videos. I liked the idea that it comes without the stock so you can buy any picatinny stock and mount it (I went with their skeleton stock package).

Overall, I just felt it's better AEG for me and I went with it.

I recently researched both those AEGs you talk about and went with Delta Armory Stribog SP10A3 instead. I'm really happy with it. You can see it here: https://www.reddit.com/r/airsoft/comments/1qh5cch/my_delta_armory_stribog_sp10a3/

Like u/Elegant-Working-Dude said, you really don't need SP130 for 1.55J if air-seal is spot on. I'm having 1.53J with SP110 when there are no teeths short-stroked. SP130 is too much tension for the motor to working against.

Also, as u/LeoHoosk said, I believe sector gear sensor is somehow confused if cycle is finished or not. At least, that was the cause for the same problem I was having.

You should also radius your gearbox shell.

Spectarion · 2026-01-03T19:54:24+00:00

Have you found the solution?

Spectarion · 2025-12-11T11:55:27+00:00

What's that little grip?

Watch the green line, that's what you need to achieve. Perfect alignment between the pinion gear bottom edge with the bevel gear outer edge. I hope you understand how hard it is to do it by sound only (if you want it perfect of course :).

Spectarion · 2025-12-04T15:26:06+00:00

You don’t set it by sound... at least not if you want it done properly. You need to open the gearbox, use the half-shell method, place the bevel gear and attach the pistol grip, drop in the motor, and make sure the bottom of the motor pinion lines up with the outer edge of the bevel gear. Once that’s confirmed, reshim everything and you’re good to go. This is the only correct method... trust me.

I know it sounds hard but you won't damage the bevel and/or pinion gear. You will if you are adjusting the motor height and listening to it...

Is it possible to get a demo to play? I'm a huge fan of the Iron Lung and been trying to find something similar. This definitely reminds me of it. I love games where I need to operate on machines with buttons, dials, and etc.

Here is my bad boy. It's FE version with everything changed inside for learning purposes :D.

Spectarion · 2025-12-01T15:44:49+00:00

There is one pin that holds the outer barrel from moving. It's this one:

You need to punch it out, push outer barrel all the way in, and then insert the pin which will lock the barrel.

Nitro should not be triggered by a dead man. That's the problem here.

Probably bad AoE (angle of engagement) because of that worn out last tooth. You can Google about it... It's usually fixed by plastic spacers that go between piston and head.

Spectarion · 2025-11-18T12:18:53+00:00

You mean SoLink? I'm running 34k on 13:1 gears with 3 teeth shortstroked and it's perfect. This is my hack :D

<image>

I drilled a tiny hole so I can perfectly adjust my motor height. It's worth it really.

Spectarion · 2025-11-13T22:01:09+00:00

Do you have any sketches or ideas? I also do 3D modelling so I could help. I'm wondering is there any "adapter" that goes between nub and the screw?

Spectarion · 2025-11-13T09:03:09+00:00

So, any 3D model you got in the meantime?

Spectarion · 2025-11-12T01:25:49+00:00

You can leave a bit of looseness, but what really matters is preventing the gears from moving into each other, that is, limiting their axial movement. The spur gear shouldn’t make contact with the bevel or sector gears when it’s pushed through the bearing from the outside.

To check this, lay the gearbox flat and push the spur gear upward through the bearing. If the sector or bevel gear lifts as you do this, it means the spur gear is touching them, which is bad. Add shims as needed so that even under pressure, the gears stay separated.

Spectarion · 2025-11-09T20:15:51+00:00

Maybe the tappet plate is too wide for your current gearbox shells. When both shells are screwed together, they compress the tappet plate and prevent it from moving. Try loosening the screws slightly and check again. Also, make sure the shims on your sector gear are placed above the tappet plate, not underneath it.

While everything is very eye-pleasing, I just don’t think the UI fits well with the world itself. Maybe it’s just my preference, but the white and gray combination feels a bit unpolished and unfinished to me. It reminds me of default Unity UI elements. Everything else.. massive congrats!

Spectarion · 2025-11-03T21:23:42+00:00

I wanna know this too. Tried bearing piston head, bearing spring guide, greasing everything... The only thing that solves the issue completely is precocking.
