iv got the same problem , when i conect my batery the motor starts to spin and i cant stop it unless i disconect my battery pack , i havent got a clue i think it just could be a dud bored what bored have you got cuz iv got the v35 in my halo .
the motor will spin continuously without anything blocking the eyes in the feedneck,thats how halos work.WHEN YOU SAYS YOU HAVE TO DISCONNECT THE BATTERY PACK DOES THAT MEAN YOUR ON/OFF BUTTON DOESN'T WORK.
