I was climbing out at about 70-75 knots. Climb was still positive and from memory at least 300 - 400' per minute. As it was quite windy and not head on I wanted to keep some airspeed up my sleeve. I was positively climbing, albeit slower than normal due to terrain also increasing my density altitude.
I have a digital EGT / CHT in my aircraft. I'll give Desert Goats approach a try and see how I go.
In reading these comments which are very helpful thanks, I have noted that I am perhaps not paying enough attention to my CHT on climb out. The old dial is always in the green but my digital one does indicate over 400f regularly on climb out. Perhaps I'mm climbing too hard too regularly?
