New to Tanks- r/c airplanes for 35 years. I bought a tank online and it does not work. Charged everything up and traced the power as far as the circuit board. I can not return the tank, dealer does not answer my emails. Is there a common problem, or is it possible to install "normal" r/c electronics. By the way, the only name on the box or instructions is BATTLEFRONT TANK EXPERT EDITION OVERWEIGHT SCALE 1/12. Any help would be appreciated.
