Yep, the Dinah KAI is theoretically going to be good against the B-29 due to it's speed, but the lack of armor and no radar inhibits it I think.
Since it lacks armor, I think all the speed does is make the Dinah's lose more planes to defensive fires without further disrupting the attack any.
Purely speculation on my part, but as a disruptive fighter the Nick can do it better with less losses and comes months and months sooner.
There are three squadrons that only upgrade to Dinahs that I can see, so I will make them and I am researching it, but Dinah is not a big choice for me if they can switch out to other NF they will.
The NF Dinah actually has a slower climb rate than the KAI Dinah F that I am using strictly at night now. Therefore, I plan on using the III KAI Dinah NF in the same manner, low altitude, low percentage CAP and see what happens.
