Hey there,

Do you have an understanding of basic aerodynamics? Have you flown planes before? I guess if you are breaking into this hobby then do it with the DF5#4 (Walkera Dragonfly 5-4). Its a coaxial heli which means that it has two rotor blades and is extremely stable which is excellent for getting used to the cotrols and orientation of a helicopter.

If you want to go with a tail motor drive like the one shown in the link then I suggest you try and get a R/C flight simulator and practice on that for a while. These things do take time to learn and crashes are inevitable in the beginning stages.

Best of luck to you dude!
