I ordered 6S, 2300KV fi70mm version of the Ducted fan.It wight 183g, it was with D2842 2300-6s engine, 12-blades. Max total power was only 1440W (V=24V and I=60A, Thrust under 2kg) using full-charged battery 6S - 5000mAh, 20C-30C, ESC 80A, in this condition engine heated itself very quickly over 140 Celsius degree - you can achieve such Power (1440W) only for few seconds if you do not want to destroy fan (the engine was too little for such power). There was never achieve, wrote Power=1638W and Thrust=2240g. The Seller parcel was very bad packed (The fan was several time hits during transport), fan without any carton box. Only one A4 sheet of manual inside. There was not the inscription "POWERFAN" on the item. Not recommend.
The engine was very bad balanced, safe power for it that only 1.1KW and thrust only 1500-1600g. I do not recommend, it is not for fly, too big risk of fire!!!
