PB, please don't credit your fast solo only on your instructor and an electrical device. Please let us know that most of it was due to your willingness and persistance to learn this great hobby. Also did you use a sim?.

I was fortunate enough to have a sim to practice with and 20+ years in cars and boats. I was able to solo in 2 sessions with my instructor and I give him alot of credit because he let me fly the plane and didn't keep taking control. If I was too low he would tell me to get some altitude. when practicing landing he let me fly it to the ground from the first time I tried. he coached me he didn't take the plane everytime I got out of shape.

So PB congrats on a fast solo and hope your are enjoying flying. I still have to stand by the join a club and get an instructor, not only did I get free flight training but I made alot of new friends that have helped me alot since my solo.
