That's a bold claim! I can get a big rip in 5 seconds starting from cold with my Zion. With my FW2.1 I need to hold the trigger for 40 seconds to 1 minute to be able to get my first hit.
The power output figure for the FW3 hasn't been released but seeing the power source used and the discharge rate of your average NiMh, I'm willing to bet it can't output as many Watts as the Zion. Also the Zion is voltage regulated so you don't get much of a power drop when the cells are depleted. With my FW I need to hold the trigger longer and longer until it's flat.
Also the Zion has a patented heater tech with much more surface area, and as
@nosmoking said a larger airpath diameter...
But I hope someone will be able to do a side by side comparison.
@Shit Snacks looks like he could be the one...
The question is: can the FW3 hit as hard as a desktop? Because this is what we compare the Zion with...
