I have one. It is an F-27 Stryker and not F-16. Flies superb! I fly mine with the stock battery and also with 8 cell Kan 1050's. I moved the battery bay slightly forward as the CG from the factory I felt was slightly aft. Also, the silver plastic piece that covers the receiver and esc will come off. They use a sticky gluish type of stuff to hold it on. It would have been better if they had you epoxy it on. Also, this plane aint for beginners. You have to go easy on the sticks at first or else it will nose dork into the ground.
