If he wasn't so well known, I think that a lot less would have been made of the 'servo transparency' issue. The AAIB report has been a long time in coming out, I suspect due to the McRae legal team and family trying some damage limitation.
He was a professional risk-taker, you can't drive at 120mph down country lanes and tracks safely and, whilst he was very good at it, those skills do not automatically transfer to helicopter flying. Very sad that he took 3 other people with him when he discovered the limits of his ability.
