I’m in the finishing stage of completing mine as well.
Just waiting for the ZDZ 50 I ordered 2 moths ago to come in.
Gadgetman, are you sure that there is nothing wrong with your scale?
Mine plane weights 9lb 3oz without the engine. I figured if the motor, ignition, battery and muffler weight 4.5lb that will still get me under 15lb which is my goal.
