I have a Sainsmart Jr mini DIY drone kit. It has 4 rotors and they all spin but the drone simply does not take off. Any suggestions appreciated.

Can you show us photos of the drone and a link to the kit assembly manual?

Here are some possibilities:
1) The rotors are not properly installed with regards to CW and CCW rotation.
2) The polarity of the motors are incorrect.

Thanks. The possibilities 1 and 2 - are they the same - i.e. if polarity is not correct, CW and CCW rotation would also be incorrect?
Sorry for the typo- should be Sainsmart not Sinsmart

The most likely cause is a bad battery.
How old is it?
Do you have a good charger for it?
What is the voltage across he battery terminals at full power?
