So then I went into a descending spiral at around 75º with about 1800 rpm set until I eventually got down to a suitable height to re-enter the free lane at Woodley.
Beagle the spiral is high speed closed throttle not great for cooling )) a spin is better and I believe was a technique used to stay over a relatively fixed point for a cloud break used in the days of poor nav! The spin being slow speed and stable way to descend through cloud!
