Screw Notes:
When ordering after-market screws, the diameter is the threaded part (not the head or hex-wrench-size used). Also, threads can be different pitches. Length is only the threaded part of the screw. A nice cap-head screw is better. They have a slightly taller head that original factory screws (more metal to grip tool and less change of stripping out).

Most replacement screws need to be very close or exactly the same as originals. For instance, the motor screws can not really be any longer or they might scratch the internal wire-windings. If this happens, the motor will likely be damaged. If you go another mm or more in length, examine and measure first.

The screws to attach the official white Quanum Nova prop-guards are 12mm long. Be very careful to NOT use these screws without prop-guards attached (since they screw-into motors).

The four metal alloy motor spacers (under motors) are about 2mm thick.

All screws are metric. Stock screws are a soft metal and will strip-out if not careful. The included tools are also soft-metal and not very good. Better to use only quality tools on screws and they might last a while and not strip-out.  Once stripped-out, you might have to force a SAE-hex tool or small flat-head screw-driver into hole or use a Dremel to cut a small groove.
