TT stock head question

[ferincr]

I have a R60 and a 90 SE (plastic head on the 60 and the TT metal on the SE).
I read a lot about people running these helis with +12 -12 of pitch.
I can't seem to get more than +10 -10 on mine is there any way to get it (with the stock components) and I'm missing something or do I need to get after market parts to do it? (washout arms, mixing levers?) the collective tray seems to go the full travel but I only seem to get around +10 -10:dontknow.
Does it has anything to do with link lengths? If my very limited brain is not lying to me it seems like the only way would be to change the length of the mixing levers or something like that.
Any help??? Thanks.

If I remember correctly you have to lengthen the pitchrod and the two longest rods in your head. Its somewhere in the back of your manual.

I looked at that but it states that for "extreme" 3D setup the pitch angles in idle up1
are +10 -10 :confused:.
I'll try to fidget with the rod lengths to see if I manage to get a bit more bite.

Laurens got it.
I did this with my 60. Shorten the collective linkage til tray almost bottoms out... and the 2 long linkage rods, i think ya shorten them too.

A tip from the field: your collective servo arm shouldn't be 90 degrees, it should point slightly more to the ground.
