well i have a pizazz and i have a os 70 four stroke. jsut got a new hitech cp radio for it so i am wondering set up also with that radio. have had just a normal radio in there for two years now and have had the throws set up for full movment as far as they can go. have loved all the controll that i have had with this but need more functions, looking forward to see what that new radio will do for me and the plane. have seen a pizazz go with a jr radio in it and it was amazing what the plane will do for you . you can get the plane to slow down and float so much you can land on the tail wheel , i have been doing this with just a standard futaba but at a higher speed. have fun though its a great plane..
