Agora 2 a casa 4 compras sofrem reagendamentos de entrega, fora os atrasos, entregas em horários bizarros tipo 7 da manhã ou 23:50. Tá difícil, tem coisa que no ali tá chegando mais rápido.
After 115 revisions, I think I finally cracked the two biggest problems with the D8PA, my homemade HPA engine: the Joule Creep and the size.
The Joule Creep used to be so bad that the only way to run it was as a DMR / sniper. There was no playing it as an assault rifle. This new version fixes that.
**What changed in V1.1.5:**
- **Joule Creep solved.** It is now consistent enough to run as an assault, not just a marksman build.
- **Roughly 40% smaller.** It went from a hand-span of hardware to something that drops straight into a standard **Gearbox V2** shell.
- **New valve setup:** a modified commercial **QEV** (quick exhaust valve) plus updated solenoids. The QEV pushes the air down the barrel much faster.
- **Fully DIY:** printed on an FDM printer, with very few tools, built at home from parts anyone can source.
**Performance (my own chrono + air tests vs a Polar Star Fusion F2):**
- ~**72%** of the F2's air efficiency
- ~**97%** of its shot performance (as a DMR)
The simplest proof I can show is moving the nozzle backwards, which is what let me miniaturize the whole system this much.
**Files:** the **V1 files are free and already available.** This V1.1.5 is the direction the project is heading, the next gen that fits a V2.
Still a ton of work left (rewiring the FCU, cleaning up the loom, more chrono testing as an assault build), but I wanted to share where it is at. Happy to answer questions about the valve setup, the print, or the numbers.
I already fixed it by cleaning the cutter housing and checking if it's moving freely, but I was surprised this happened mid-print.

After a long time without updates on the dual solenoid HPA, here is a video testing it on the chrono and checking its range. Both the body and the engine are fully 3D printed.
