My second Synergy and it is just amazing! High quality and sharp looking too. It would be nice if they could at least in include a $5 blade holder in the kit but not a deal

Synergy E7 Special Edition Flybarless Torque Tube Electric Helicopter Kit
I have to agree with the other review of this machine, absolutely top notch. Ever single aspect of the E7 Special Edition has been scrutinized and made as close to perfect as I have ever seen. I recently converted my E7 to the Special Edition model and I am as impressed as I was the first time I flew the E7. With over 250 successful flights logged in a row the numbers speak volumes about the reliability, and with the hands down absolute best customer support, if something does go wrong rest assured you will be taken care of!! I don't own a Buggati like Mr Feil :) but if I did I would buy the roof rack so I could take this machine everywhere I went!!
