im afraid those motors at the site is too small. the car be quite heavy so i need bigger motors. im still looking for used brushless motors on ebay .
i look most for hacker motors like c50 , plettenberg motors and lehner motors , the more big ones.
do i get a great price on a brushless ducted fan system , i`ll buy it

by the way , do you guys know what material the chassis on the Batmobile is ? has he soldered it together ?
