I can't answer your queries with exact figures as it's years since I last flew a 105 but I spent 750 very happy hours in them.
Most of my time was in the D model on the North Sea where it flew well because it was generally cold & windy. However I flew the CBS in Oz & I don't recall any power problems but you won't hover on 1 engine. Slow run ons were easy, especially with winds over 10-15 knots.
One of my favourite helis, so strong.
