if your crash broke the blades, especially right at the grip, then your spindle (the small metal piece that goes through the top of the headblock and connects the two blade grips together) and the main shaft ( the metal shaft that runs through the head assembly down to the gears) are more than likely bent. most crashes, even minor ones can bend both easily. i would buy a few spindles and main shafts to keep on hand just in case, as these are basic crash parts. take the blades off and use a 1.5mm hex driver and turn the hex screw inside the grip. if you see the grips wobble any, then your spindle is bent. also grab the main gear and spin it slowly with your hand. watch the head assembly, look for a wobble. if so, then the main shaft is bent also. i would definetly check these first, and then proceed with the setup.............td
