products is ok ( description is ok) you are able to cut off sound ! good because sound is string.. the connector for battery is not sm2p like description or picture but it's a jst connector. it could be interesting to specify dimension of battery case (15mmx98mmx60mm). 2x18650 are possible (check picture) voltage is 8v so it's ok.
Very bad delivery. Box was cut and a lot of tape was used. Removing the tape but the glue wil stay. It was a gift for my grandson. I think I get a second hand product. Also the radio controlled connection is bad. Never order a toy like this by AliExpress again.
