I would also go with the Cap10, nice capable aircraft. Not sure about SSs thing with CS props, yes it can make things easier but it is also a good thing for people to learn on a fixed pitch aircraft so that they learn how to control the power in manouvers - depends a bit if they are
just going to fly the same aircraft all the time or if they will fly others with Fixed pitch after - easy to go Fixed to CS, going the other way is when you can easily get an over reved engine.
