Glad i found your Threat Bruno, i also realised a few days ago, actualy a friend at the Club, realised my TT front drive gear was lower than the AR Gear as you said... and when i found your post last night i found this interesting.. i also though about what i could have made wrong.. but after 23 flights, i never encoutered any problem.. so i decided to go through my manual to see what i did wrong, since today was time for my 20th flight maintenance.... and i was amazed, at page 17 of the manual, if you take a look at the upper picture front he heli side, you can clearly see that on the technical drawing, the front drive gear as also the same amount of upper versus the Anti-Rotation gear... and made me realise, if Align also comes to this point.. guess i haven't done anything wrong?... as a Graphic designer, i can tell you that when we do technical drawing, we place in our software the picture as template, and we redraw the picture over with vector lines, so the drawing was made from a picture that was like this.. so i'm curious to know, is it really a problem that needs to be fixed, or was it really made like this... let me know how it works with your solution, and i'll keep mine as is, and let you know how it goes....
Se pictures.
