Help
 

Hi everyone my name is Thomas and I have been a long time rc fanatic. I have over 10 cars but i only use about 5, the others are for spare parts. recently i have acquired a robitronic br-50...that does not run. Today I am going to disassemble the entire car, troubleshoot, test, and then hopefully run. I have a few questions before begin. I bought the car from someone who hasn't used it in a few years. I was wondering what i should check first just to save some time.

thanks,

Thomas
