I am playing DDC, and not sure if a patch was done or Da Babes is the reason, but you now have to pay PPs to convert IJA Light Bomber units to Medium Bombers. Alot, in fact, 75 for a 12 plane Chutai, and 100 for a 27 plane Sentai.
I'm not complaining about the rule, I like it, probably more realistic. But it does change a bit how you manage aircraft production.
Before this change, I would ramp-up Sally/Helen production, and phase out Light Bombers. They would disappear pretty quickly from the front, except for Training/China, and even then by end of 1942, they would only be used for training. I didn't produce a single one, turning off Sonia production day 1, and just using the stock of Mary/Ann/Sonia you start with.
Now, might have to use them long-term. What do others do with the LB units?
I think I'll probably bite the bullet and convert the Sentais, leaving some units for Training. I'll probably leave the 12-plane Chutais alone, and deploy them to China.
What about production?
--The ANN appears to be the best bomber, actually; heaviest bombload, best range.
--But you can't build it, so do you keep Sonia in production?
I still don't see building the IDA, or using it for other than training.
What is everyone doing with the Light Bomber units?
To answer your question Q-Ball, the cost to convert between aircraft types was added with the latest official patch (it was added in one of the beta patches long ago). Not sure exactly how the cost is figured, but if you choose to deviate from the official upgrade line, there is a PP cost based on the number of engines and/or aircraft type.
As you have seen, to change your Sonias to Sallys (for example) you pay a PP cost based on aircraft type IIRC. While if you change from Oscars to Nicks, it is based on the number of engines (I think).
As to what you should build...hard to say. In the end you might be best off to leave the Sonia and Ida in production. While both are hopelessly outclassed, you are already producing them so you don't spend HI and supply converting factories. The Ida does have a camera, which makes it slightly better as a recon plane (and you can use it as a light bomber of course). I still try to convert over as many of the light bombers to mediums as practical, as they are just enough better to make it worth the cost.
