RE: second plane
The Aeromaster might be a bit of a handful for a recently solo'ed beginner. My second plane was a Tiger 60 but I think they are discotinued. I would opt for a larger plane in the 60 size range because it is more visible and gives you a better view of what you are doing when you apply movement to the controls. Also, the visibility gives you a slightly better view of the aircraft during approaches and landings. I was totally amazed with mine when I would come in for a landing and put slight inputs to the elevator and watch the response of the plane. Mine had an older refurbished OS .61 SF on it and it flew just fine.
The Revolver is also an outstandint sport plane. I have a Skylark 70 sport plane that I really love and believe that it too would be an excellent second plane.
