Due to the long delivery time of another motor, I had temporarily installed this one in my replica.
This one has been lying idle for a while now and can go through.
With this motor, you can use a battery for longer. Brushless motors are (much) more efficient.
With a standard 1:18 gear set and M100 spring, I ended up with a ROF of 32.
Fast enough, but if you want to keep it intact longer, you can easily slow it down with an adjustment screw.
