Repairing the PCB power input

This seems to be a weak point with my heli. The power feed from the battery to the control board isn't very well attached... a hard landing can cause the solder joint to break - resulting in a 'dead' chopper.



After removing the cabin remove the cover of the main control board by undoing the three small screws on the switch side. You can remove the screws the other side to completely take out the board but it's not really necessary. You can see the wires from the battery top left - they should both be attached to the board.



After re soldering them I coated them in silicon sealant to make a firmer attachment.
