You're 6'4" and you fly a Mooney? Wow
It would be hard to fly a Mooney if you aren't 6 foot. At 6'4" I still
have to move the seat up several notches. The Mooney is like a sports
car, you sit with your feet almost straight out in front of you. The
firewall actually has feet areas cut out for all that leg room. My wife
could never fly the Mooney. She's 5"5" and not only can she not reach
the rudders but she also can't see over the glareshield. In the Bonanza
you sit up like in a truck. My knees always seemed to be hitting the
bottom of the panel, Getting in and out is easier in the Bonanza but
sitting up front, the Mooney is clearly more roomy.
I have the F Mooney (about 10" longer than the older models). My boys
are pre-teen and fit just fine. I've ridden in the back seat by myself
and was ok. However, two full size guys in the back seat is very tight.
In the Bonanza you have a bit larger cabin but it costs 2-3 gal/hr more
to push that larger cabin through the air at the same 150 knots.
