Maverick - regarding "I don't know yet if the first taxiway turn is more than 300ft so, I don't know if I got down in the length of a football field which is my goal. I'll have to find out the distance. Next, I'll try coming over the threshold at 50mph. And, I will spend more time slow flying with 20 degrees. I've heard one should fly with 20 degrees getting up and getting down but, I'm not there yet."

I use the length measuring tool in Google Earth. Amazingly accurate.
