The air cylinder can't keep up with rof. Increasing pressure on the other side of it will help but still 50ms is a bit too fast

Jepp i notice that!
Just tried 50 and 25ms! Maybe 100 or more will do!
But if i ad a 5 way valve to control the cylinder so it cycle at the maximum extension and minimum then i can find out how fast it can shoot!
But for now i think i will do the magazine in front of the left T, a bit easier to make something when i dont have the Solenoids.

Okej

Some progres today! have redesign the cylider niples and got ride of the rear mounted T!
I put it in front and have made hole for the BB´s!
So now i put the T in front of the air inlet T, much easier!
The hop up rubber in place just need to make a new nipple from the air tank (buffer tank),
And make a piston for the breech!

Will post some pic´s later and video!

Think the magazine will be the hard part!

Any tips to make a quick coupling for the mag?

Peace
