Engines very well. Control center to weight ratio as the transformer coil too unstable. Arrangement of plate in the switch box is not optimal for the treatment of connections. Clamping screws be operated very gently for cable cheap = oneway = must otherwise is not possible, a second use. Schellenberg Hotline can forget. Do not be reported despite promise to this day. The bracket for the motors on goalposts I myself have made since the supplied round for goalposts bring no stable hold. Now it works.
