There was a build video on the Devil Pro 450 v2 where the torque tube mesh was to tight , looks like to solve the issue new align gears were ordered for the front and rear, could someone please post the part Numbers that were ordered to fix the issue. I'm confused on the numbers of teeth on the gears , just want to order the correct ones to fix the issue. Also please tell me how smooth this should be, should you feel the gears at all or should this be a smooth as butter as I have seen on these groups. first torque tube helicopter for me. Thanks in advance.
