Yes the Kadet .40 is a great plane!!!
But just to be different i really liked the HOBBICO superstar .60
as my trainer of choice.......Maybe it is just a power thing .......but then again it flies damn good and you can see it well too.......and quite durable........Supertiger .61 in it and you got a wonderful trainer that will do more if you pour the coals to it........
But The Kadet .40 is a good plane
