Two 60% scale clipped wing Cubs in close formation

[dominicm]

These guys have been practicing their formation flying for a long time. That's how they got so good at this.

They are flying Bill Hempel Clipped Wing Cubs. These radio controlled aircraft have a wing span of 18 feet (216 inches) and are designed for the 3W-275cc engine but Azza and Sonny used the ZDZ 420B4-J. The weight is approximately 94-96 pounds.
