Remove all the training aids for the PTS and it flys semi-scale. Takes offs require higher airspeed and a gentler touch on the elevator. In the air it still fly's like a "advanced trainer" (snaps like no war bird should). Landing take more attention as the ailerons are less effective and you most be a lot more careful with the elevator! After flying it as a trainer and then flying a semi-sport/race plane I went to fly it as a sport plane and it still had tendencies of a trainer (slow roles, mushy stalls, ext.) but could snap role so fast that it caused the screws holding one aileron servo tray into the wing to strip and then it flung the servo tray out! but all was well as i had became good at landing it.
