Well this is stupid, I just called the place I was planning on ordering the gears from and its like $2000 just for one gear... a 3 inch diameter internal gear made out of plastic is $2000....................... from www.rushgears.com I was going to order from them because they had 3d models of every gear they sell so i used those in this 3d model of the car, anyone know where to find cheap gears? I a 24 pitch 72 teeth internal gear, and a 32 pitch 34 teeth gear. the rest I can get at like towerhobbies. but I cant seem to find those anywhere else!
