I got my Invertix back from Encore Rc after having a couple of issues and I can not say enough about their customer service just excelent. So this is new Beta 2.1 Firmware and here is my first flight with it installed and my first flight in over a month with the actual Invertix. I had 5 more flights that day each lower, faster flips and more of them in the row. Now its time to turn up the rates.
