So I have ran 10 batteries with the smooth yellow plastic prop adapters from Ralphy/Shapeways. I will post some pics later tonight. I am in the unique position of having ran original yuneec, the maytec carbon fiber ones and now the Ralphy adapters with Autel xstar premium props. So I have averaged 1 minute and 50 seconds longer flight times with the stock battery. The longer time is great but what I am really happy about is the motor temps dropped by 38° verses the carbon fiber! So the Ralphy adapters run cooler and longer than after market carbon fiber. I have yet to compare motor temp of original yuneec props after one battery verses the Ralphy adapters with Autel props. I have had no problem with screw on props loosening, they also seem less noisy. The only fitment issue I had was my set of adapters were snug at the top on the inside where they butt up against the crome top of the motor shaft. It is not off by much though. I just took a lexan body reemer and opened up the hole a tiny bit. I hope this helps everybody. Thanks Ralphy!!
