RE: beginner looking for RC helo
the hk450 is one of the best price, I have 3 and 1 trex 450 sa, the hk 450 is a 100 % t rex compatible. also check Deal Extreame for servo; speed control; brushless motor; gyro; and lipo batteries if you want to save shipping, their shipping are free and they're cheep.
Don't forget to get a pitch gauge, you need it 100%.
