i found a really good power driver.. a blacker & decker rota-driver, its small, low power, found it at Target. part no pp360 , 4.8 volt. 1/4 drive socket. about $25.00. the team integy quickpit screwdriver set fits. i know i know integy isnt the best, but its what my hobby shop had. now if i could just work up the power to put the jato back to gather.
