#1 What is the normal operating pressure?

Normally the Ion will operate at about 140-180 psi.  With upgrades this number can be dropped.


#2 What kind of threads do Ion Barrels have?

The Ion uses Impulse threaded barrels, which will also work on the Smart Parts Nerve.


#3 Do I need an Anti-siphon tube in my CO2 Tank?

Yes. An Anti-siphon tube, if installed properly will keep the liquid CO2 out of your  regulator and marker. This will increase efficiency (more shots per tank) and reduce venting of excess pressure as well as reduce the amount of wear on o-rings.


#4 Are there any reviews of after market upgrade parts for the Ion?

The links to the reviews have been moved to the top of this page.  If you are all the way down here, you missed them.


#5 What o-rings are used with the Ion?

The Ion manual and Supplemental Ion Parts List (A & B) contains o-ring information for all of the o-rings in the Ion.  The problem is the "part number" they provide is confusing if you do not understand the type of information they are providing.

In the manual, the part number for each o-ring is listed as ORNsomething .  The something value is the Standard American "AS568A" number.  This is a number used to identify a specific o-ring size.  Now the size of an o-ring consists of three measurements, the Inner Diameter (ID), the Outer diameter (OD) and the Cross Section (CS).  In simple English, the Cross Section is the width.  The yy value is the hardness.  A Durometer is used to measure the hardness of various substances.  Shore A is the numerical scale for measuring the hardness of rubber.  Any of you skaters should be familiar with the durometer of skate wheels.  This same value applies to o-rings, the higher the value the harder the rubber.  The Shore A scale is from 35 (soft) to 90 (hard).

Now with all that said, the information in the manual should allow you to buy replacement o-rings wherever available.


#6 What is the Dwell on an Ion?

The dwell setting is the amount of time that the solenoid remains open, which due to the way the Ion functions is how long the bolt will stay in a forward position.  The dwell time determines the volume of air that is used to propel each paintball.  An increase in the dwell will usually increase velocity.  There is a "point of no return" where raising the dwell will no longer increase velocity.

The Dwell is adjusted in .25 millisecond intervals.  The lowest dwell setting is 3ms.  So when you lower the dwell all the way and then add one (one flash) the dwell is at 3.25ms.

The stock dwell setting is 52 "flashes" from the bottom, which is 16ms. 


#7 What is the Recharge Rate?

Contrary to what the manual will lead you to believe, the design of the Ion does not allow the user to set a rate of fire.  In actuality, you adjust the recharge rate to increase or decrease the delay during each firing cycle.  The Rate of Fire Down setting increases the recharge rate and the Rate of Fire Up decreases the recharge rate.

Its a combination of the Dwell and Recharge rate that determine the actual max ROF for the Ion.

The recharge rate is the amount of time between each shot, measured in milliseconds. When you increase the recharge time, you are actually increasing the amount of time between shots, which in turn decreases the rate of fire. 

The recharge is measured in one-millisecond intervals.  The lowest recharge setting is 30ms  So when you lower the recharge all the way and then add one (one flash) the recharge is at 31ms.


#8 Can I remove the magnet from the stock trigger?

Yes, the instructions are provided here


#9 Can I use an Ion without the plastic body?

It's your Ion, technically you can do whatever you want.  With that said, I personally would not do it for the following reasons:

  • The only thing holding the eye board for the Ion in place is the outer body.
  • The breach of the Ion is removable.  Without the outer body holding it in place the breach can unscrew and cause some not so good things to happen.
  •  The outer body also provide clearance (spacing) to cover the internals.  Without the outer body you could have a gap between the trigger frame and the body or if the body is screwed to tight to the trigger frame you could damage the body, solenoid, board or a banjo.

#10 How do I set the ROF on the Ion?

The Rate of Fire (ROF) is a combination of the Dwell and the ROF setting.  The ROF setting is actually the recharge rate.  The Recharge rate is the amount of time the electronics will wait before acknowledging another trigger action.  Think of this as Smart Parts version of the Debounce feature found on Wicked Air Sports Equalizer boards.

  • The minimum Dwell is 3ms and each flash adds .25ms
  • The minimum Recharge is 30ms and each flash adds 1ms.
  • To zero out the Dwell, select Dwell down (solid red) and hold the power button until the yellow led no longer flashes.
  • To zero out the Rate of Fire (technically the recharge rate) select Rate of Fire Up (single blink red) and hold the power button until the yellow led no longer flashes.

Dwell: # Flashes up from the bottom Dwell (in ms)

 

Calculation Action
What is my ROF if the Dwell is flashes from the bottom (using dwell up solid yellow) and the recharge is flashes from the bottom (using ROF Down single blinking Yellow)?

NOTE: The stock Ion electronics are capped at 17bps

What Recharge do I need if my Dwell is flashes from the bottom (using dwell up solid yellow) and I want to only shoot balls per second?

NOTE: This is how you would set your ROF to 15bps for PSP, CFOA, etc rules.

#11 Is there a computer animation of how the ION bolt works?

Yes there is, thanks to Brent "Twiek" Crowe from PBNation.  Ion Bolt Animation

The Ion uses an open bolt electro-pneumatic blow-forward design similar to that of the Automag and Freestyle.  It is not a spool valve like the Matrix. The back of the bolt is always pressurized.  When not firing the front of the bolt is also pressurized. The design of the bolt allows more force on the front of the bolt, vs the back of the bolt even when the pressure at both ends is the same.

During the firing cycle, the pressure holding the bolt back is removed and the the bolt is blown forward.  When the bolt moves sufficiently forward, the air passages in the bolt become open and air is released down the barrel to propel the paintball. At the end of the firing cycle (when the dwell time expires) the front of the bolt is pressurized and the bolt is pushed back and once again held in place by pressure from the solenoid.

The QEV mod allows the pressure holding the bolt back to exhaust faster, therefore decreasing the bolt cycling (movement) time.
