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.

Synergy E5 Flybarless Torque Tube Electric Helicopter Kit
I must say "This is the real deal". Very nice parts quality, everything went together perfectly, the machine work is awesome, very solid platform. I put the Rail mains and tail blades on it, MKS HBL980 tail, JR DS8717 cyclic. Got a chance to maiden 12/28/13 (break in the weather) WoW. I don't think you can go wrong with Synergy. Plus on line support team are a great bunch of people. They will answer your questions. Best I have seen on the web. A must have heli for your fleet.

Synergy E5 Flybarless Torque Tube Electric Helicopter Kit
Been flying my E5 for about 9 months now and is my "go to" helicopter. The versatility of this kit is great too. Flying mine on 12s and just so smooth. Would not recommend as a first heli but if your looking to move into a solid preforming helicopter, take a good look at this one. Good size and great performer.
