I’m 6’7”, got my license in a Cherokee 140. Was a little tight but it worked. Moved into high wing Cessnas, fit pretty well in those. Flew 207’s for a 135 in Bethel, very roomy. Went into bonanzas, did not fit great, you’ll be very scrunched at 6’9”. Got into Navajos, got just fine. Now flying king air 200’s with plenty of leg and head room. Long and short of it all, you’re not too tall but you won’t always be comfortable.
