I ordered this battery for my Revell Nano Quad. I did however get some larger battery with 110mAh.
Actually, you should not assign stars for a wrong delivery, but since the battery can be installed with little effort in the Nano Quad I press times to keep an eye.
The additional 10mAh make only slightly noticeable. The original battery weighs 2.74 g and 110 mAh battery 3.74 g. The extra weight interferes in my opinion, not because the pitch lever the same rash of 50% shows (measured with the Hubsan x4 Remote Control).
An estimated flight time with this battery 5.5 min
