I am not up on electrics either but I did notice that when I first started out with my I Con it didnt have enough power to plow through the snow and take off so I taxied around down the field and back..by the time I got back the battery must have warmed up because it had more power and it lifted off easily...Sombody suggested keeping the batteries in your pocket untill you are ready to fly...I however am with Brian...I like Glow or gas better..Electrics have their place...I like my ICon for early mornings when everybody is asleep and the water is calm...
