This is the Synergy E5 Flybarless Torque Tube Electric Helicopter Kit. The E5 is one of only a few “true” 550 class helicopters which can swing 550mm blades right out of the box. The large disk size provides the stability and “pop” most pilots are looking for in a high performance helicopter. The E5 was also designed with a path for growth in mind. The E5 can be configured as a 6S 550 class helicopter which is perfect for the budget minded pilot that still wants a high performance helicopter but does not want to spend a lot of money on batteries. Since the E5 battery compartment can handle virtually any battery configuration and the motor mount can accept a variety of motor choices, the E5 can easily be converted into a 12S 550 class helicopter or stretched with existing parts into a 12S 600 class helicopter. The E5 is a true modelers helicopter which gives you the options needed to build and fly how you choose.
