they can be expensive..this is actually a cheap one.. about $200 with extra parts and a wireless cam for some movies..lol..

there is a free sim called FMS you can use with your keyboard and/or your controller can hook to the usb ports on some models.. making it easier to adjust .. I will find out soon enough how rough it is... this is also a 2 prop heli which suppose to hover easily???? I just want to scare the heck out of the cats with it actually...
