I am a few hours away from my first solo...one of the biggest challenges I am dealing with is seeing out of the cockpit (over the coweling) and being able to fully use the rudder pedals...I am 5'6". Combinations of seat adjustments and cushions make it manageable, sort of, but not ideal. Also, I find myself so close to the firewall that it is difficult to pull very far back on the yoke...I am in a 1973 172.
