I will have to second the Post above by RC David,
I recently bought a Thunder Tiger Mini Titan - 450 e-CCPM Heli.
(my previous experience being a Blade cx2 co-axial heli!).
The build quality of the Mini Titan is superb with Raptor pedigree - very nicely designed. More straight-forward to build/rebuild than the Trex too!
Mine came with an AcePower 2200 25C 3S Lipo. Appears nicely suited to this Heli.
Get around 7 - 8 minutes of nice hovering / FFF.
The MT provides a rock solid hover (as said, possibly more so than a 450 TRex), however capable of full 3D, thanks to the E-CCPM, as and when you want the extra excitement!
You might also like to checkout the Mini Titan SE - which has full carbon fibre tail boom/fin + full metal head and tail components.
The MT is available in a number of built stages - from basic kit, to kit + electrics, to ARTF (everything included - requiring just the main blades and tail be fitted)!
Definately include the MT as an option!
