i can tell you you wont like a motor tail rotor.
they are very unreliable, the tail motors burn out VERY fast, and are some of the most unstable heli`s made.
now with that being said some folk`s say if you can master a tail motored heli than you can fly any heli on the market, but these same people will tell you if they had it to do over again, they would have NEVER have bought a tail motored heli.

but thats on you man, if you want to spend lots of money repairing a heli than get the tail motored heli.
honestly i would get a belt driven tail. much more stable and reliable.
