The early Firecrackers had slightly thicker wings than the Starduster and the later Firecracker wings have a totally different airfoil section.
Even though it flies with a larger yaw out than a conventional wing, it does not seem to hinge or yaw in maneuvers as the leadouts are separately adjustable and the down line is about 1.5" back from the up line.
Brian designed the Starduster in about 1982 to be flown in windy and turbulent air at his local club. This plane was taken to the Worlds where I believe it was VERY windy and he performed well with it.
It certainly doesn't "rock n roll" in wind like the lower tapered models do.
I agree with PJ in that it does look "professional" when your gear all color matches along with your clothes as well.
I also agree that it puts your brain in "competition mode" when you wear "flash" clothes and have a flash plane.
Even though it is 70oz, you must remember that was WITH fuel (battery of 12 oz).
When people say their PA75 model weighs 65oz, that does not include 5 or more ounces of fuel.
Also, the weight is closer to the balance point so there is not the barbell effect that the glow models have so it still turns "snappy".
Another advantage of electrics is that the balance point doesn't alter through the flight.
