Product description this drone looks like it's just come out of a sci-fi movie the blade guards look just like big fan motors surrounding the blue body shell everything is small about this ready to fly drone (95x95x50mm), even the price it even comes with a 24ghz radio system to provide quick control given its size, it still. Ron ballard of wren turbines usa and his fantastic cessna 425 starting up wren 44 k turboprop powered twin the wren 44 k turboprop engines feature kero-start, 10 mm prop-shafts, the latest zicoy ecu's and a magnetic pump that has no seals that can wear out or leak with use. Also the micro turbines spin a lot faster than the full size turbines, up to 500,000 rpm compared to 15–20,000 rpm, most drone motors spin between 10–30,000 time compared to an electric or even nitro motor is longer meaning if the turbine does slow as it is loaded, it will take longer to return to its set speed, a big drop in.
