Thank you John and Fred,

 

I really thought so.

 

I asked a couple of engineering friends of mine and they could not come up
with anything concrete other than, ".to figure out the range of twist of the
wire when making a torque meter."

That made perfect sense to me, but I thought "Naw, there has to be something
else to this. It just seems so important. What a putz.

 

Thank you guys,

Ren

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).

Hello guys,

 

Why is torque meter calibration important? How does it impact the end result
when the torque meter is used?

 

This is what I think happens. We wind to a certain torque with a given size
rubber for a given size plane. We fly and observe what the plane does in
flight and how many turns are left on the rubber. We make whatever
adjustments are needed to fulfill our next flight. We fly, observe and
adjust some more for optimum flight duration.

 

Why does the torque meter have to be calibrated if it was built to handle a
certain range of rubber sizes?

There is still going to be a range of meter deflection and ultimately that
is what we use to judge our next flights adjustments.

 

What am I missing??
