Reviews

Our customers share how our tools helped them build drones and achieve performance goals

"The 1780 has been a great piece of equipment. We discovered your low cost sUAS propeller test stand at AUVSI and I think you guys have done an outstanding job bringing this tool to the community. Keep up the great work!"

Robert McSwain

Aerospace Engineer

NASA Langley Research Center

"Having a reliable ready-to-use-out-of-the-box thrust stand solution, like the Series 1585, was critical to meeting our need to test often and quickly iterate on designs in our development of the toroidal propeller."

Dr. Thomas Sebastian

Senior Staff, Structural & Thermal-Fluids Engineering

MIT Lincoln Laboratory

"We've used a lot of other test stands in the past, specifically from China, that haven't gotten very good data which has led to expectations that haven't been met. The Series 1780 was spot on. When we did our very first test flight we flew for 45 minutes, exactly on the money what we were expecting."

Marc Stollmeyer

Director of Product

Inspired Flight

"We have just finished our tests with the 1585 - Test bench. Everything went very fine and we are extremely satisfied and content with this test bench. Thank you for all your support!"
