She was a really fun build and a worthwhile project.
I managed to get both front and rear guns to rotate which was fun and delicate to say the least.
There is an engine sound generator fitted as well liked to the throttle.Working Navigation and running lights.
Even using the kit provided rudders which I linked all together the turning circle is very good.

I had the same on some flags I bought for my UBoat…no Swastika.
Political correctness I guess,sign of the times.
