I'am 6'7 and do not have any problems. I have an FAA first class medical and I am going for JAR-FCL medical in a few months but I do not think there is any height requirements. I think it is worse if you are to short. I have never flown the warior but I did not have any problems in cessna 152 with instructor. In cessna 172, I even need to put the seat forward.
