HobbyZone Super Cub RC Airplane Model Kit For Parts Untested Battery May Be Bad

Contains everything. I tried charging the battery and it did not appear to get fully charged. I believe this to be the issue. It kept flashing red for hours. When green it says charge complete The controller works and turns on. Looked like a battery did cause corrosion on 1 spot seen in pics Has all other pieces Is good for replacements or if you can get it up and running you can get this for cheaper. There is a cord on the plane that I do not know where it went to. It just goes beyond the top and appears to have no purpose but must go to something See pics Again is for parts I cannot get it to work. Is extremely large box and will cost a lot to ship
