I am looking at the size of the pilot bust for my new Pitts and it recommends 1/5 scale. I have been checking most of the sites recommended in many of the RCU threads. I have found some 1/5 scale, but one that I really like is listed as 25% size. With 1/5 being 20%, would a 25% pilot be too far out of scale to be realistic? Just wondering before I go and order one.
