Beginner Nano qx flyer. Haven’t flown this in a maybe 6 months due to the area I live in. I know I can fly in the house but haven’t. Urge hit me today and I charged my 4, 1s 3.7v 150mAh battery’s and fired up my Spektrum DX6. I noticed all the props were not turning, if I tilt it they would start but go back out. I checked for binds and wire checks. All good. Trims were all set to zero but it wanted to go backwards badly maybe cause the blades weren’t always wanting to turn. I have my radio set to half speed as I’m not good at flying. Flip the switch to go full throttle, all props did better but still needed trimming I felt was way off. Any ideas of what’s going on? Bad batteries, sitting too long? I get 5min of power from battery. Help please. Thanks
