If you check your radio manual I am sure you will find that it has the helicopter mixing software in it.
The Hawk is a very good choice in entry level heli's and in Canada the Century heli's are very well priced and very well supported.
Also check the posts here on Raptor clutch problems (e.g. the "Raptor Clutch failed" on this forum on the weekend) and head flutter problems. These are non-issues in the Hawk.
