Hey Steve thats 100 mph indicated would that be around 90 mph ground speed with no head or tail wind? My airspeed indicator is always about 10 mph faster than the GPS says I am. I know when I flew with you we did 110 I,A,S, along I 10 over the railroad tracks. eatherway thats hauling butt. And 4800 rpms is not bad for that speed what degree do you have your props pitched at?

Indicated airspeed is rarely accurate, the only figure I take notice of is a GPS figure doing a run each way then taking the average and you got the exact true airspeed .
It is lovely seeing that 'magical '100 ' MPH indicated all the same.
