@RYT,
Would you mind describing what happened on the crash? I ask for a reason. There have been many discussions of "crashed on first flight" on the Forum. None would have been prevented by RealSense. I suspect you would benefit more from things the forum members can offer than you can from RealSense.
I did read that a pilot had contacted his local Yuneec Germany and they said there was no difference, there was a photo posted on here from somebody who makes skins and the plus module had an extra hole or sensor on the underside. But don't waste your money, keep practising, it gets better.
