As I have been attending a training session today - in connection with a forthcoming professional exam - I thought it appropriate to post this photo. Sadly however, no military aircraft were involved in my training.
Japanese aircraft used by training units were usually painted overall orange - this makes for colourful and unusual models. The bi-plane in the foreground is a Yokosuka K5Y 'Willow'. This is another pre-painted Japanese model by (I think) F-Toys.
Lurking in the background is a two-seat 'Zero' by Doyusha. The difference in coulour is less pronounced in reality than the photo indicates - the orange on the Willow is a bit washed out by the camera flash.
