We are now shipping the RCbenchmark Series 1520. It measures overall efficiency, current, thrust, voltage, and motor speed. The device communicates with our open-source software, which displays and records data, and controls the motor manually or through a scripting system.

Whether you want to increase flight time for aerial photography, or performance for racing, the tool will help you obtain the data you need on your motors, propellers, ESCs, servos and batteries quickly and accurately.

A year ago, I posted here asking if people would be interested in a low cost, automated thrust stand. My colleague and I, both recent graduate from M.Sc. Mech. Eng., developed the Series 1580 dynamometer, and we obtained excellent feedback from a large number of businesses and universities. Many hobbyists asked us for a simpler, more affordable tool. We heard you, and we are now offering the Series 1520 for $165.

Get it at $149 if you order before March 1st! Additionally, for a limited time, we will refund an additional $40 if you post a video review about our tool, which will lower the product’s price to only $109. Check the product page to see if the offer is still valid.

Here are the specs:

Voltage (0-35 V)

Current (40A continuous, 50A burst)

Power (0-1400W)

Thrust (±5 kg)

Motor speed (100k RPM)

Overall efficiency (%)

USB interface

ESC manual control

Three servo control ports

Output data to CSV files

Powerful scripting abilities

Safety cutoffs

We want to offer more than a test tool. You might also be interested in our ongoing video tutorial series on motor and propeller theory. For more more information, check out our website or the Series 1520 product page. I will be available here to answer questions on our tools and on motor and propeller testing.
