OK Dar, although I didn't name names in that first post it's obvious I was aiming at one of your statements in that OS 55AX thread where you stated "Don't do any break-in with less than 6" pitch. Cooling is impaired and reducing the diameter lessens the load without hampering the cooling. In this case, a 10x6 would load the engine like an 11x4." I disagreed with you but had nothing to back up my disagreement so I did this experiment precisely according to the prop figures you mentioned. Now, because the results I got showed it had no affect, you're shifting the goal posts and making silly arguments about what I should have done (in your opinion).

As for inferring that I might be using a totally worthless type of thermocouple to fault my readings, I use a contact type thermocouple which plugs into my digital tacho/multimeter and has been calibrated using the phase transition points of dihydrogen monoxide.
