We modified the 450 frame with a TBS clone frame, commonly known as the "dead cat" configuration.
The "dead cat" config allows a prop free video recording view, plus it seems to be more stable.
We flew the APM 2.5 quad in ACRO mode, without stabilization. It is actually much smoother than the normal STAB mode. Go try it!
