Don't let anything come inbetween you and your goals
I am 4'9" and flew a C150 and C172. I used 2 cushions to adjust myself in the C150. When I started flying C172, i couldn't get the full control deflection due to the higher seat level. So my instructor suggested to modify the cushion in an incliner way so that I get get to do full deflection. And it did work well! What I'm trying to say is, if you want to do something real bad, you have to find a way to overcome the obstacles you face. Happy flying everyone!
