I didn't want to spend two thirds of my training time driving, I am a busy man! I searched around for a training school using the model of aircraft that I wanted to learn in, who would train me on my own airstrip, so I could sleep in my own be and spend nearly no time driving to my lessons. I trained to pilot certificate, passenger and cross country in twelve days. Only one thing that I didn't take account of was how long I would take to get my plane built so I could stay current. I agree that a compacted course has limitations in the area of retention but I don't think that would have been any issue if I was ready to step out of the school plane and go on flying. As things are now I will need a fairly extensive refresher to get back up to speed.
