Perhaps the programmable brick is the key,
you said in "warbird modus" it wasn't so nice to fly, but surprisingly well in "speed modus".
With my Gee Bee I wasn't able to adjust the gyros and had to fight against
AS3X - I didn't like it that way.
So there seems to be a nice solution, I'm interested ...
But first of all I'll test it in "normal modus" ...
