Noob R/T Question

Welcome to the forum. You don't have to open your gun to "tune" your r/t.
There should be a silver fitting toward the rear of the gun. Use the small
screwriver that came with it to turn the screw. The instructions tell you how
to do it better than I can. The sweetspot is the amount of pressure you need
to trip the sear but light enough so that the r/t can "bounce" the trigger
back to the starting position.

  You tune the R/T by tuning the screw on the fitting on the right hand side of the gun. 

  You can't just let the valve wide open.  The further the valve is towards the "closed" position, the easier it is to maintain the full auto effect, but the slower it will fire.  As you move towards the "wide open" position, the rate of fire will be faster, but it will be increasingly more difficult to maintain the full auto effect.  You have to start at the "closed" position and slowly turn the screw until you can achieve the highest fire rate possible/desired, yet still be able to make the gun fire like it is automatic.  This takes patience, practice, and lots of c02.

  Imagine that the "sweet spot" (the place where the R/T makes the full auto effect) is a window or something.  The less the screw is turned outward, the bigger the window is, but the slower the ROF.  The more outward the screw is turned makes the ROF higher, but closes the window.  You have to find a happy medium so that you can get high ROF while still holding the trigger in the "window".

  I hope that helps, because I think I just confused myself!
