In video is strange behavior, because front sensor was not connected.
Also, when connect ir sensor, you must do a little mod. Will see on picture. Just need to left only little cap, orherwise, sensor will not detect bb. I used alu tape.

Front supressor needs to drill bigger holes. I was too lazy to made them bigger in sketchup, because scetchup is pain in the @££@.
