Not the highest hours (31 hours to pilot certificate including GA aircraft) but it took 10 years in 4 different aeroplanes. In order , Piper Tomahawk, Huges Lightwing TW, Drifter and solo at 12 hours and flying it to the 16 hour mark. Then a 8 year break, welcome the Jabiru LSA 55, loved it. Got back up to speed and passed my pilot certificate in it 15 hours after a 8 year break. Oh yeah, I like Jabs.
