The helicopter is an Ergo 60 Sport with a P-5 Webra engine. Modifications were made to increase lift and reduce slop, the uncontrolled movement on a servo. To increase lift, semi-symmetrical carbon fiber blades, an aftermarket drive gearing, and a tuned heli muffler replaced the stock parts. To reduce slop, the nylon servo arms were replaced with aluminum servo arms and servo output horns were added.

The helicopter is controlled with a JR XP642 6 channel radio transmitter. On the helicopter is an R600 receiver, five 517 ball-bearing servos, and a Piezo gyro. The receiver, servos, and gyro are powered by a Sanyo 1000 milliamp battery.
