You can be an instructor on any subject that you have a firm understanding of, we instruct by sharing knowledge.
The issuance of and the posession of a certified flight instructor license only demonstrates that you have satisfied the authorities that you have passed " Bureaucracy "
My advise to you is become friends with the aircraft engineers and learn from them.
If you have difficulty identifying who they are, look for someone not dressed like they just returned from fighting every war known to man.
