More aerobatic and durable? I have owned both a GP Shoestring and a VF Edge. The VF plane beats the GP plane for both any way you slice it. The Shoestring is an amazing plane to fly, and the assembly is easy. However, it is fragile in the undercarraige area. Once broken, it can be a pain to get back to par. On the other hand, the VF planes are build like tanks, but without the associated weight. The foam core wings are light and strong, and the fuses are built to amazing quality standards. I would also say the hardware for the VF planes far outclasses that of the GP package. That covers durability pretty well, let's move on to the fun part, aerobatics.

The VF planes are obviously based on scale representations of aerobatic planes. The GP Shoestring is a pylon racer. The Extras and Sukhois are designed for the advanced aerobatic maneuvers. The GP will turn on a dime at break-neck speed, but is not built for such maneuvers. I wouldn't hesitate to own either one again in the future, but for the reasons mentioned, the VF planes emerge victrious.
