2-28-2015 Version 2 is coming. Modeled after the Turnigy thrust stand, I will be hacking a ordinary kitchen scale for $10 and building a stationary all in one thrust scale that can measure up to 11 lbs of thrust. Check back or simply follow-me and you will see my next posting.

I developed this double arm equal arm balance so that I could measure the amount of thrust any particular motor and prop combo can produce. This way I can tell how heavy my model can be and still stay 3D or maintain flight. All parts are equivalent for the left and right sides so the scale components will not skew (add or subtract from) the measured force. The double arms keep the motor and prop parallel to the measurement plain and the force transfer paddle always flat on the scale. I use a regular kitchen scale to measu
