Here are some pics of my TT mini Titan with recent metal Head upgrades from thunder tiger.Enjoy.

Metal swashplate and baseplate added.

Nice 

So what stage are you in your flying ? Circuits, loops/rolls, or (beginning) 3D ?

Post some videos.  Heli videos from Indian fliers are so rare !

Question : At what point should a newbie into heli consider upgrading to metal head . What advantages does a metal head offer ?
Will it make it more resilient to crashes ?

Of course the metal head would improve crash resiliency (but in the in-frequent case of a part of the metal head breaking up, the replacement cost also goes up).

The bigger reason is safety, when you start doing aggressive flights (especially pitch-pumping moves).  If you are doing just hovering and circuits, upgrade is not an urgent task (it is more of a "nice to have").

Another advantage is that wear and tear is also less for metal heads, and enhances overall performance (reduces vibration as there is less "slop" and "flexing").
