Extra 300L conversion
 

Hi all,
I´ve recenly adquired an Extra 300L from CM (China Models) JAMARA on the box, but I have seen the movible parts of stabilizer there are very small for 3D Fly. I´m thinking in to make it again more big.
Some one has these plane and can help my?
Can I do 3D flying with this small stabilizer?
The ailerons are big, very good to do 3D fly, but I need your help before mount it.

Thanks.
