I really enjoy that stuff when the weather cooperates,good friends,planes,food,beer,campfires,wives at home so we can talk about them(imagine what they are saying bout us?). I dont know if its just me or my servos, but with the Do and the X100 my rolling harriers are quite slower than what you see in videos. I dont really mind at this point,they still look like RH's,pretty high alpha so I cant complain,I just imagine its a 40%. My 3-d really came around this summer,just increased my flying time and voila!!
