Or not. I've got less than 300 hours on my PP-ASEL ticket. No commercial, no instrument, no complex, no high performance. Not even tailwheel, though I'll have that eventually. I still think I'll be OK to teach day VFR flight.
Teaching is more about teaching than flying. Like all of us, you’ll learn a little bit more about the flying part as you continue, but I think where the majority of “traditional” instructors fall down is the ability to adapt to teaching something they haven’t been specifically taught.
I have had no formal training as a teacher or instructor, barring a couple days while in the Army back in the late 70s. The first time I taught a class I was learning the material the night before as I worked up the lesson plan for the next day. I was teaching the hardware architecture, maintenance, troubleshooting, and repair of a very large mainframe computer system that I'd never worked on personally, and the students were Chinese with barely any ability to speak English. I think I'll manage. I certainly couldn't be any worse than a few of the so-called "real" CFIs with whom I've flown. Some have been great. Some have been just been instructing to build enough hours to get their next gig, and I hoped that happened very quickly.
Which ANY “full CFI” would be able to adequately teach without any specific aircraft/system/avionics knowledge or experience, obviously.
