When Should I start #2.
Immediately, one thing you learn in this hobby. Always have another ready. Because no matter how good you get, things happen and "BAM" plane is gone. I had flown 2 different planes for over 2 years, and lost them both within a 2 week period.
My son went from a trainer to a SIG SE, and flew it and landed it better then he did his trainer. I highly recommend this plane for everyone.
