I saw a few posts about the stress cracks. Well I have a few minor ones on the motor screws. DJI only has a few flights with no crashes. Anyways, I pulled the housing and ordered carbon fiber/kevlar material and will cut into small 1/4" hairs. Do I need to reinforce the long screw shaft on the other side of the light, or is it just the motor housing area? Do I need to do top and bottom of the shell as well, or just the bottom shell piece? Thanks.
