[NSRCA-discussion] Too quiet - more throw calculation spread sheets

[Keith Black]

Here's a throw calculator I put together a while back that does the following:

#1: Calculate the required control horn length given the servo arm length, desired max servo deflection and desired max control surface deflection. 

#2: Calculate the required servo arm length given the control horn length, desired max servo deflection and desired max control surface deflection. 

#3: Calculate the control surface deflection given the servo arm length, control horn length and max servo deflection in degrees.

  The list is just too quiet so I thought I would pass along this handy utility.  It is an Excel spread sheet to convert surface deflection measured with a ruler into degrees of deflection or visa versa.  It is modified from one available on aeroperfect.com.  I added the ability to enter the deflection angle to get a ruler measurement.  If you haven't seen the product offered by this company it appears to be a quality digital inclinometer (angle gauge) that can be used for setup.  A bit expensive but I have been using the module from a Smart Level which works well but too bulky to attach to a control surface.  Hanger 9 offers a similar device that if it was made well would be just what the Dr. ordered, but its poor construction in fit tolerances and repeatability make it all but useless.

   

  Has anyone tried this product in actual practice?
