A quick progress report on the little k100 daycab:
back of the cab, showing some custom work on the air cleaner and battery box:
and last but not least, the sound system i went with:
this is a Dasmikro micro sound unit. based on youtube videos, it sounds alot like the gtpower. if you look closely it is servo taped to the side of the ESC, and the red a nd black wires lead around to the front of the ESC where the mini speaker is located. it connects to the throttle output of the receiver, and an aux channel. using the aux channel allows you to select alternate sounds, like a horn.
