Spend the extra $20 Buy the black series instead.
In testing the Warhead Base 20k RPM motor within a 14.09:1 DSG setup on an SP150 spring, I observed performance metrics that were somewhat below expectations for such a specialized application. I'm obviously running fast gears, so I thought the 20k brushless would have been better than the black series for torque.
I was wrong.
The motor exhibited a 19A draw on semi-auto, yielding a 36ms trigger response and 35 RPS— which is... Okay. Far below expectations however.
Contrastingly, the Warhead Black Series CNC 36k RPM motor presented a significant leap in efficiency and performance, reducing amp draw to 14A, despite its higher operational speed. This led to a dramatic increase in RPS to 60, with a semi-auto cycle time improvement to 24ms and an ultra-responsive 8ms trigger response with precocking enabled. Moreover, the efficiency gains were ridiculous, with the 36k motor consuming approximately 0.093mAh per shot, a notable improvement over the 0.19mAh of the 20k motor. This translates to an almost comical improvement of 49% decreased energy consumption per shot over the 20k motor. underscoring the superior efficiency, and SOMEHOW SPEED? of the 36k option.
I was able to verify that this was indeed not a fluke in the design of this motor, but in fact a structual one. The cogging torque is SIGNIFICANTLY lower on the 20k brushless for some reason, which suggests a lower magnetic interaction between the rotor and stator. (WHICH WOULD MAKE NO SENSE)
My theory is the 20k brushless is actually a high speed (60k?) with a pentitometer installed to limit the RPM to a maximum of 20k. No idea why they would do this, but its the only thing that makes any sense.
Given these findings, I recommend enthusiasts and competitive players consider the Black CNC 36k RPM brushless motor as a superior alternative to the Warhead Base 20k RPM model. The 36k motor not only enhances performance dramatically but does so with greater efficiency, making it a prudent choice for those seeking to maximize their airsoft gun's potential.
Just get the warhead black series. It's better in every way.
