if i look at the technical design than it still works the same (normaly closed pipe than when ...

You could vent (trigger) the QEV with just about any electric valve. Yea but than you need to disconnect the compressor every time you want to shoot right ? (i am exacly considering it cause than the hose of the compressor wouldnt be in the way) but than again i cant use it in later projects( i am ...

Lol i was exacly looking at that the same ebay link this afternoon :D but i thougt that it would not act the same as a slide valve (close the compressor part en open the qev part) or does it ?
cause otherwhise i am going to order the electonic one, cause it would probably take 3-4 weeks before it ...

Yea it is, they fit togheter. Thanks for the help

its defintly 1/2 (http://www.spudfiles.com/forums/files/qevebay_110.jpg) threads for the qev, maybe you got some kind of other qev ?

i also dont live in the uk, sorry but what do i need to do to make my gun D:

cause your instuctions arent correct i think... does it even mather wich diameter pipe you buy or can i just take any kind of pipe that fits with a reducer and n cap. than if so whats the formule for the volume of the ...

Simple: 1/4 male to 1/2 female reducer + 1/2 male male pipe (lenth as you like, but if you tell me the pressure you are going to use, I can give you a number.) + 1/2 female end cap.

i just got the parts and that isn't right a 1/2 inch(we have mm so 12.5mm) is already de QEV itself, so.. what do i ...

Thank you! thats all i need to know, right now. i think i gone do the large pvc chamber, there are enough plans for that around the web and its much cheaper than a co2 tank, and since i dont have a place to charge, i will pretty much trow a way money ;) maybe on a later stage i buy a tank with reg ...

Hey, you are fast! faster than i can reply :D
