you must have been a natural if you were landing on your own in 8 hours. I have 60 hours in and still have no solo because my landings are not consistent. One problem I believe was changing the plane I flew, but another issue I believe was my instructor saw me as a cash cow and wasn't helping me to develop the skills I needed to develop my landings. I suppose getting nervous about blowing one landing after another didn't help. How did you do it so quickly?
