If you are going to disagree with the advice given that's your right. But you really shouldn't give attitude back and that's how your last post came across. A 17oz tank full of gas is almost a pound. A high performance plane like the Funtana needs to be light. Why carry the extra weight just cause it came with the plane? A 1.20 glow burns almost twice the amount of fuel a 20cc gas does. Unless you want to fly 25 minutes at a time you are hurting the performance of your plane.
Not trying to start a war or offend.
