LOL looks like I´m not alone
look around suddenly it´s full of selection fire, solenoid...
it´s like everybody it´s in the era of advanced electronic and I´m still in pneumatic age

Hmm, seeing as I can't find a solenoid, I'm gonna machine a simple clamp to attach an actuator to the slide valve. I'll be back in a couple of days with a prelim cad. Can anyone run a ggdt to find the fps reached bya 150 g Shot with a 350psi, 1ft long, 1 in wide chamber, with a qev

My bad, 1/2 in barrel and qev. Do you think the chambers big enough?

The chamber for me is enough for high pressure. How long is the barrel?

Hopefully about 2-2.5 ft long

Why not longer? Is there room for ~4 feet?

I'll maximize based on size, might have a 2.5 and a 3.5. Depending on what I need, I can thread the barrel and receiver.

I did the GGDT with a 2.5 ft barrel, the muzzel velocity is around 100 fps (I don´t know much about your valve so...) muzzel energy around 75 ft*lb.
No erros so I would say the design is ok, even through I would use a light projectile for more fps and find the sweet spot of max power (I did a the same calculation with a 100g projectile, muzzel velocity 145 fps, muzzel energy 78 ft*lb).
