RE: Twice the scale, now how about the motor?
Looks at how the size, weight and power needed goes up on the different sizes of the same plane, in this case a Super Sportster.
Super Sportster .20 engine 48" span weight 3.5 pounds
Super Sportster .40 55" span weight 5.5
Super Sportster .60 61" span weight 6.5
Super Sportster .90 72" span weight 11.5
Super Sportster 2.0 82" span weight 13.5
