This paper presents an approach to validate a wind tunnel propeller dynamometer applicable to Group 2 unmanned aircraft. The intended use of such a dynamometer is to characterize propellers over a relevant range of sizes and operating conditions. under which such propellers are susceptible to low-Reynolds-number effects that can be challenging to experimentally detect in a wind tunnel... https://www.lightemupsequences.com/flash-sale-Bachelorette-Party-Decorative-Picks-Pack-of-24-mega-choice
