First Flight Test Results of UAVmainframe V6

An encouraging result in the ongoing development process: A short period mode identification using data from UAVmainframe V6 on Skyhunter. This one was manually flown and does not yet have control feedback sensors. The vehicle mass properties are also unknown at this stage, so the absolute numbers are not that meaningful. Yet the proportions make sense for this aircraft, and the uncertainties of the estimates are quite low. To be continued...
