Capacità ( mAh )
I got 2x 4.5 fans they are great the fans are balanced well. However, the cone screw is about .5 mill out of centre and they don't make a 6mm replacement shaft.6S 5000mAh Turnigy 25C, Neu 1512/2.5Y 1100kv motor, 60A, 1350W, 3kg thrust, maiden flight on Bobcat here: watch?v=mNInoz4DmUUWHEN THE HELL WILL HK GET THEM BACK IN STOCK!!!!!

I completed bench test produces lots of thrust. Using my unit in a F-4 building from scratch.holly s%^& ok so usually you come across cheap stuff and youd be like wow waste of money lol... dude im running this on 8s 29.6v 2250 mahs.. omg im in my room and im afraid to push the throtle to even a half lol... its too much... only downside is motor gets hot and maybe ill get a bigger esc current one is 70amps thanks hobby king!Estou utilizando com KB45-10XL 1200kv Brushless Inrunner, otima combinao. Nao vibra, tem um bom balanciamento.Tried a Hyperion 4025-890 in the bored out housing. See my previous review. Used 10 new Turnigy 5000, 30C cells. Turnigy 100amp esc. 112 amps 4.1Kw. Reduced throttle to 85% to give 95 amps and 3.3KW constant. Batteries only got warm. Had to strengthen fan motor mount with support cut from circuit board and glued to web. Combo powers a 13lb, 42oz per ft sq Sabre well, staggers off grass then really gets up and motors once "on the step".Nice unit for the price. Did need to be balanced. just added CA to light blades. KB45 1600Kv motor. going into old Byron Mig15
