Dear All,
Have been flogging around in a 1989 BO105 - 11000 hours + on the frame,
for a few years now. All of the flights were Police related, and have to say that the one minute warm up - although a great idea, does tend to knock the rapid response that plod require. It's a sad fact that some types of operation do tend to knack the hardware somewhat, but we seem to limit our 'chips' with the Facet filter setup, apart from rebuild debris that is. The old 105 did tend to leak some, but providing the labyrinth seals were well run in, and the weather above zero (c) the "rapid start" and take off could be performed ok. The problems you have heard of with the C20B are correct, but they must be understood in the context of the job the craft is being put to.
