Yes it's a t2050 and a p6 plug(fresh).
The fuel is Red Max(clear color)30% nitro and 12% oil(fire and ice).
I already did that.the thing is that when i come from WOT to idle it revs up a little after 2-3sec,then drops at normal idle and doesn't seem to load up that easy even if i richen up.[:@].

I did turned the middle needle in about 2/8ths and it seemed to help a lot but i think it needs more "care".
