Bag the Hun Khalkhin Gol Ki-27's

I'm moving on to the next phase of the painting plan now, with eighteen 1/600th scale Tumbling Dice Ki-27 Nate fighters ready to be assembled on the workbench. These are simple two piece castings, consisting of the fuselage and two legged undercarriage, so putting them all together shouldn't take too long. They also have a simple light grey-green paint scheme, which is the easy bit, but they will need the Sentai and Chutai insignia painted on as well, which will be far more fiddly. 

24th Sentai, 1st Chutai

11th Sentai, 1st Chutai

11th Sentai, 2nd Chutai

I'm painting half of them as 24th Sentai, 1st Chutai aircraft, with a red and white striped rudder and two horizontal bars on the tail plane, while the other half will be 11th Sentai, 1st or 2nd Chutai aircraft, with red undercarriage legs and either a white or red lightning flash on the tail. This will be pretty fiddly to do but I'm going to try anyway. Unfortunately, I'm really busy with work over the next three weeks so progress will be very slow, although I can probably chip away at the painting in the evenings to get it done?
