Re: Calibrating a Torque meter question

My impression is that you want your torque meters calibrated if:

(1) You want to compare what you are doing with what other modelers are
doing for the same event and maybe even the same design of plane and/or
prop.

(2) You are trying to find initial settings for a variable pitch prop
(but I am not).
