HOBBY KING HELP

HOBBY KING MAKES IT VERY DIFFICULT TO GET ANY WARRANTY, I HAVE A NEW GRAND TUNDRA, THE WING PCB SWITCH AND CONNECTION SET IS FAULTY, LIGHTS WILL NOT WORK AND ONE FLAP WORKS WHEN IT FEELS LIKE IT, VERY UNSTABLE SITUATION. ALL I NEED IS A REPLACEMENT SWITCH PCB and CONNECTION SET AND I CAN FIX IT MYSELF. SENDING IT BACK WOUOD COST MORE THAN THE ITEM IS WORTH,  ( ITEM  SKU 9499000296-0)
