A battle of HPA engines. Woodland Raiders for a comparison of the PolarStar Airsoft Jack and the Mancraft PDiK... "Comparison of the operation of the newly purchased HP replica with the Polar Star Jack engine and the Mancraft Pdik gen3 air motor.

In the video you can see that the engine operating on the principle of a solenoid valve gives better repeatability when shooting than the Mancraft pneumatic device.

However, after analyzing the video, I find that my replica (Mk18 from pdik) is actually not working as expected.

Also, at the moment, when I am publishing this video, the engine and the reducer are under review by the manufacturer :) The next episode will be after the corrections have been made and re-test if the results have improved."
