I maddened my E7 last weekend and i gotta say what a heli !. The heli just flys so smoothly. I did encounter some tail problems though. I was doing some climbs and then tail would kick out 90 degrees. this also happened when doing some hard 3d. I have now put the tail compensation on low on the BEASTX which has made it a lot better but when doing hard piro manoeuvres and then combining pitch pumps the tail would hesitate and wouldn't give a constant piro rate?
