There is another good one which is a bit older about the 64th Sentai and their commander Kato which is also very good. But little known outside of Japan.
A newer film is "OreKimi" or "For those we love" which is about the Kamikazie pilots. This one has nice Ki43II´s and Ki61s
Some scenes are a little hefty though.

I don't need no flames.

I just want engine starts like this (go to youtube to view):
