Fast...for a 98C
Useful firing modes
Rate-of-fire adjustment works in all modes
Installation can be tricky
Requires a good battery
Kick loosens hopper
Expensive upgrade for 98C
I have a newer 98C with ACT which accepts the e-trigger, so I decided to try that instead of the response trigger. Despite having to replace batteries occasionally, I liked the idea that I wouldn't be using additional CO2 to run a trigger.
Installation: the instructions provided by Tippmann were relatively straightforward and thorough. My e-trigger instructions had an additional piece of paper telling me to add a magnet which helps pull the solenoid back to neutral position & was apparently not part of the original design. I was concerned about using a hammer & punch to pop the battery hole out of the left frame half, but that was actually no problem at all. What was a problem was that my frame halves didn't fit together properly after installing the e-trigger components. Turns out the rough finish on the new 98C ACT models oversprays into the inside of the frame (which is obvious when you open the marker) and the thickness of the rough finish overspray was not allowing my solenoid to seat correctly in the frame. I spent quite a while scraping away the offending interior overspray (and verifying that all shavings were completely removed!) so that the frame halves fit together.
The remaining components installed without any problems, although I did apply a tiny dab of Vaseline petroleum jelly to each of the guides which hold the long pin in place -- hopefully to avoid any friction issues. Like one of the other reviewers, I had some difficulty getting the battery to sit flush inside the frame so that the grip would go on flush. Was also concerned about the battery wires breaking off the circuit board someday after many battery removals, so I applied a little bit of low-temp hot glue to hold them in place. I will try to add a couple photos of my installation to help others. Note: the sear that came with the e-trigger should work fine in any 98C ACT models, but older non-ACT models will probably require you to use the stock sear as stated in pbmike1888's review of this product. Oh - you also have to finish cutting out the little holes in the grip halves so you can access the mode switch and rate-of-fire adjustment after the grips are installed. It's pretty easy with a sharp exacto knife and a little patience.
Operation: after getting the battery installed & turning on the marker, I could hear the solenoid click when the trigger was pulled. However, when I applied my CO2 for some dry firing I discovered that after 2-3 quick shots in a row, the solenoid wasn't pushing hard enough to move the sear and fire the marker. Turns out the Energizer battery I was using wasn't putting out enough juice, even though it tested very good on a battery tester. Replaced it with a Duracell and it worked great. Not that one brand is better than the other, but you do need to be sure you have a good battery and apparently not all batteries that seem good really are good. So far, battery life has been excellent because I'm still running on that same Duracell. I will post an update if I have any further info on battery life as I continue to use it.
Also, I had previously replaced my stock trigger spring with a ballpoint pen spring. I decided to keep my original (single) trigger in stock form, and purchased a Tippmann double trigger. Combined with the e-trigger kit (since you are no longer mechanically pushing the sear) this dramatically reduces the trigger force. This setup with the ballpoint pen spring, Tippmann double trigger, and e-trigger works surprisingly well and feels a lot like a stock Ion trigger: light pull but a bit of side-to-side wobble. The 98C has enough kick that it's pretty easy to bounce, so you have to watch out for that if you perform this mod.
The rotary mode selection switch is reasonably accessible using the small screwdriver provided with the e-trigger kit. I generally prefer Mode 1 (semi-auto) and Mode 9 (Turbo), but Mode 5 (full auto) is very useful for making rate-of-fire (ROF) adjustments. For some reason, I have a little more difficulty accessing the ROF adjustment than the mode switch, but it's not something you're going to be adjusting all the time so not really a concern. What I really do like is that the ROF adjustment applies to all modes, so if you set your ROF to 8 bps it doesn't matter how fast you pull the trigger in semi-auto mode; the marker still won't shoot any faster than 8 bps. This is a good way to guard against wasting paint if you don't really need to be shooting that fast.
I still have the basic gravity-fed hopper so I cannot confirm the maximum of 17 bps advertised by Tippmann, but it sure dry-fired fast when I turned the ROF all the way up! In fact, you'll need an expansion chamber or remote line (or both) if you want to shoot more than a few balls at a time at high ROF using CO2. I don't like the looks of Tippmann's expansion chamber, so will probably use a remote line at CO2-only fields and am planning to purchase a basic HPA tank to use when I can.
The e-trigger will definitely work best on 98C's and Custom Pro's that have the ACT (Anti-Chop Technology). So far I have not chopped any balls although I also haven't tried live-firing with the ROF set above about 6-8 bps (no point with a gravity hopper). I have noticed that the amount of kick from the Tippmann's relatively heavy moving components tends to rattle my hopper loose in the feed neck -- a problem that increases at the higher ROF permitted by the e-trigger.
In the end, the e-trigger is a great way to increase the firepower of a 98C or Custom Pro, and I personally prefer the e-trigger over the response trigger. Perhaps the only major downside is that it will make you want to upgrade to the double trigger, HPA tank (or expansion chamber), motorized hopper, and all that other stuff that comes with shooting many bps. Does it really make sense to invest that much $$$ into a Tippmann, or would it be better to just buy a different marker altogether?
12/15/06 UPDATE: Battery life has been great so far. I've played several times since installing the e-trigger in October, and I'm still using the same battery. We'll see how it does in cooler weather. In any case, it looks like a fresh battery should be more than adequate to keep even a fairly trigger-happy player busy for a weekend of paintball. Haven't tried a rechargeable yet.
I also removed the reduced-force trigger spring (aka ballpoint pen spring) and went back to the stock trigger spring. I liked the feel of the ballpoint pen spring much better, but the 98 has so much moving mass that caused too much bounce.
I scuffed the inside of the clamping portion of the feedneck with some coarse grit sandpaper (making sure to clean out all the grit afterwards!) and the hopper now stays put much better.
- Works as advertised - great way to increase your 98C or Custom Pro's firepower.
- Better than the Response Trigger in my opinion.
- Best when used on a 98C or Custom Pro with ACT.
- If you know you want the e-trigger, buy your Tippmann with it already installed (less expensive overall, and you won't have to deal with the installation hassle).
- Make sure you want to invest your $$$ in a Tippmann instead of a different marker.

A $200 HPA tank is an investment that can be used on any paintball marker, but this $100 trigger can only be used on a Tippmann 98. BTW, I only paid $150 for a 68/4500 carbon fiber HPA tank at the NPPL Commander's Cup this year.

No, actually I bought my e-trigger just before the new one with the W.A.S. board was available (at least at my local shop). Had I known about the new e-trigger with the W.A.S. board, I would have waited for it instead of buying the older board. My bps (ROF) is changed by using the screwdriver provided with the kit to adjust a potentiometer on the board.
quote:Originally posted by sp62 is it true u can only use an e-grip on custom pros and u cant use them on 98 customs?
Any of the new 98 Customs that have ACT will accept the e-trigger. I think one of the other reviewers was able to install the e-trigger with minor modifications to an older (non-ACT) 98C. If you have an older 98C, you might try contacting him for more info.
