Is it normal for this to happen?

when i put my puchi on the floor i hear noise comming from it like gears running. also when i put it down on the floor sometimes it moves a little in reverse or forward by itself. Is this normal? I have a few zip zaps and i never had this happen to them. This is my first Puchi so i don't really know much about them. Any help would be appreciated. Thanks

When I turn mine on while the Tx is on, my car would buzz/hum a little. I think it's just a little characteristic of the POOCH. I kinda like it really. Makes me think the car is started and the motor runnin'.

As far as the car moving...if you check your trim you may be able to fix that. If that is not the prob, you are probably experiencing some frequency cross-over / interferance from another source like a fridge, computer, or some other appliance. Sometimes your neighbor could be sending a rogue 27mhz freq. from his/ her toy collection.

Either that, or you have an alien.
