this servo install is for low profile servo...not for those 3003..you need cut ear and stand up the servo to install ar.... you must read the manual carefully ar...otherwise you can't turn...no car is just for run straight....circuit must need to turn around ga....sigh....
then install it again!!...if you just want to take photo but not run it..then...everything OK...but if you want to put it on ground...then install it again with what manual say....there are two servo mount in the kit.....do it or not..just what you choice...but as i also play f109 and 2wd player....hope you really play it no matter on what track or even on the playground.....
