The white pusher doesn't work how it's supposed to. It slowly extends and stops as soon as it touches the dart (when loaded),or extends fully and stops not fully retracted. I dont see any mechanical parts blocking it.
I tried opening the orange servo box of the pusher. Everything seems ok in there. I can retract the pusher by moving the gears inside the orange box but when I fire the problem comes back.
It sounds like the motor needs more power. However my batteries have the right voltage and the spinning parts in the barrel spin at max rpm.
Ps: I Hope you can understand what i mean. My english skills aren't very good.
