Polarstar F1 drop in hpa engine – Releasing April 2015
For most v2 and v3 aegs! Although visually similar to the Wolverine Airsoft SMP, the Polarstar F1 uses a separate nozzle and poppet. Another, even smaller version of Polarstar Project Karl (AKA the F1 drop in engine) is potentially in the works, which could allow easy drop in to guns like the Tokyo Marui MP7 AEP!
The F1 is a high performance, universal HPA drop-in cylinder for virtually any AEG gearbox (including those with offset nozzles such as V6 and V7). It replaces the original gearbox components with a programmable pneumatic system allowing for higher performance and greater reliability. The performance range of the F1 allows it to fill any role from CQB to sniper.
The F1 has only one moving part (the nozzle) and just two dynamic seals (o-rings which move and experience fictions). This translates into extreme reliability and makes maintaining the F1 easy. To further simplify maintenance, the F1 requires no tools for disassemble.
In Short, the F1 is the most compact, simplistic, versatile and air efficient HPA conversion kit to date.
Specs: Recorded with stock VFC M4 (6.05x375mm barrel)
Velocity: 500FPS w/ .20g @ 120psi.
The F1 allows for easy velocity adjustment. Using a standard M4 as an example, velocity can be adjusted from below 100fps and up to approximately 500fps with a .20g BB. Longer barrels will increase the maximum FPS while shorter barrels will decrease it.
The maximum cyclic rate of the F1 is affected by several factors, however, 30 rounds per second is a conservative number. Most configurations will exceed this easily.
Air Efficiency: 1200 shots from 13/3000 @ 1.5J (80PSI w/ .28g)
The F1 is extrememly efficient. The patent pending design of the F1 allows for the most direct air path to the nozzle with minimum dead volume resulting in better flow, faster response and less air used per shot. Using a stock VFC M4 as a test platform, the F1 was able to fire approximately 1200 rounds for a 13ci/3000psi cylinder before pressure dropped below regulated output.
Expected release date April 2015.
