Winner of the "Best HPA Engine" in the 9th Airsoft Players Choice Awards, the dual solenoid design of the F2™ provides the same functionality as the legendary Fusion Engine™ but in a more compact, efficient and flexible design. Dual solenoids allow for the nozzle and the poppet valve to be adjusted independently of each other for unparalleled control over both the loading time and air volume used. Additionally, this makes it possible to change the firing sequence giving it the ability to operate in both true closed bolt as well as "AEG" mode. (PolarStar Filter Fitting now included)

 

The F2™ incorporates a new one-piece, lightweight poppet valve design yet still operates on the same principle as the Fusion Engine™ poppet. This valve is able to operate at lower pressures and uses less air volume to function which optimizes air efficiency.

A robust design allows for an operating pressure range of 45psi to 145psi which enables the F2™ to achieve velocities from CQB to DMR while employing only one nozzle for the entire velocity adjustment range.

Additionally, its nozzle is spring biased forward which provides a consistent loading force regardless of operating pressure. It shares the same spring as the Fusion Engine™ with both light and heavy spring options available to adjust the loading force.

Gel Ball Compatible

F2 HPA conversion kits can also be configured for use in gel ball systems.

Please contact us for information on ordering F2 systems for gel ball use.

 

Velocity: 480fps w/ .20g @ 145psi
The F2™ allows for easy velocity adjustment just by changing input pressure and does not require different nozzles to reach its full velocity range. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 480fps with a .20g BB. Velocity can vary per model as longer barrels will increase the maximum velocity while shorter barrels will decrease it. 
ROF: 30rps
The maximum cyclic rate of the F2™ is affected by several factors such as the operating pressure as well as quality of the magazine and BB's used. However, 30 rounds per second is achievable in most standard configurations.
Air Efficiency: 1000+ shots from 13/3000 @ 1.5J  w/ .28g
The standard F2™ poppet valve is equivalent to the Red Low-Flow poppet of the Fusion Engine™. However, this valve responds faster and requires less air volume to operate so the F2™ is able to achieve greater air efficiency than even a finely tuned Fusion Engine™.
(Test Configuration: Red Poppet / 6.05x375mm Barrel)

Loved this book
Format: Paperback
Assassin's Creed is my all-time favourite game series; I am enthralled by it! Sadly, right now I moved to te U.S. (I am not originally from here) and thus I had to leave my Xbox behind; well it actually belongs to my brother. My point is, while I am saving up for a new Xbox and to buy the Assassin's Creed games again, reading this novel and the one from Brotherhood has been what has saved me from going insane. I don't know why several people haven't liked it. I had no problems whatsoever with the author's style, and actually this novel helped me to better comprehend what went on in ACII because honestly some assassinations had me a bit confused and happened so fast that I didn't understand who I was killing or why. Great purchase, and I am currently reading Brotherhood! :) Insieme per la vittoria! :D

True to the game and high on philosophy, but no it's not the Fanfic lover's playground....
Format: Paperback
I read several reviews of this book and was wary initially of buying (to the point where I read parts of it in a bookstore before buying it here). Finally finished it and 500 odd pages later, this is not just a pithy sewing together of cutaway scenes and story clips. Is it classic literature? No, but it wasn't meant to be. It's sometimes hard to translate action in to book form, especially when done in the luscious hi-def glory that Ubisoft was able to achieve. But what it lacks in geographical description, it makes up in explaining and demonstrating the philosophy of the story of the game itself. You understand what makes an Assassin different from a Templar, you understand what made Ezio tick, what made Altair tick and while it is subtle, it is genuine characterization and if you don't get the memo, then you just aren't trying. While some complained because Sophia wasn't painted with more detail or that the relationship between some of the characters could have been explored better (like the political tension in the royal family for example), I'd still argue it wasn't necessary. This is not Suleiman's story or Yusuf's story, nor was it a love story though there is one; it's Ezio's and Atair's stories and the simplicity of their thoughts and actions were well drawn. It wasn't meant to fill in the gaps, fanfic is much more satisfactory in those cases. The only drawback of this book is that sometimes it borders on being preachy, but I don't think the makers of this game were exactly subtle about whose corner they wanted you to be in. True to the game, absolutely direct about it's philosophy, and it doesn't try to masquerade as anything more than it should be for 10 dollars.

Love love love Ezio Auditore!!!
Format: Kindle
I am a huge gamer and having played Assassins Creed many times, it was nice to see “inside” what we are RPGing. This book was a lot of fun to read and very insightful. “With you until the end, Ezio!”

Good not excellent
This book started off with lots of promise. It got my interest straight away and kept it there for a few chapters. It includes some intesting history facts of the age and enlists some of the characters of the age as well all of which I found very intersting and unique. However the general theme did not change. The Protaganist got better and better at killing and never really got into trouble. He goes from one adventure to another of similar sort with the same outcome. He kills everyone and gets away without problems. I had trouble finding the climax and wondered at many points if it was just a story that went on and on without an end. Overall a good light read if you don't expect much surprise or complex intrigue.
