Engine test Stand for Brushless Motors

I built this engine test stand to test different motor and prop combinations for my multirotors.

This design is a little different than others i came across while researching engine test stands. I use a hanging scale attached to drawer slide to measure thrust. I employ a wattmeter and a kv meter while testing. then I took the data and put it in a spreadsheet to help visualize the data and help making prop/engine decisions..

Please check it out and tell me if you have any suggestions to improve the design

Brilliant! I had been thinking of creating a setup to test motor prop combos... but my ideas were nothing compared to this. WOW... that is all I can think to say.

Well WOW, and that I promise to copy it and give you credit if anyone asks.

I like your video. I had a similar idea of using low friction drawer slides and a digital scale like yours. Very cool to see that it works so well. I actually ordered a 2,000g and a 4,000g dynamometer ($6 ea. on eBay) for my prototype that I'll be assembling soon. I like your recording charts and spreadsheets too. Great work - thanks for sharing.
