Also when the battery gets low it just stops it doesnt even spin the blades which causes you to think there is something wrong and not the batteries.

X5 batteries are pretty cheap and plentiful, just not for this model.

If you already have Syma X5 models, the batteries you have for those will not work for this helicopter

The battery stays connected, no issues there, but it is different from other Syma X5 model variants
