Hmmm yes

>> Kollisionspunkte im Bereich des Rotorkopfes bei großen Ausschlägen:
>> Mischhebel am Rotorkopf bei großen Ausschlägen:So there seem to be a couple of spots where you have to grind away some to get more pitch (probably you figured that out...)
Follow the green arrows.
The mixing lever can deflect far enough that the ball links come off => grind off the edges
Especially the lower side is important.
>>Eine weitere verbesserte Variante stellt diese Maßnahme dar (Danke an Frank Bräutigam):Then, they changed some ball heads against longer ones (107-108 version).
Ball link on the see-saw: Shorten the thread by 1.5 mm, continue using the brass washer.
To get the same cyclic range as before the mod, dial down on the Tx by 8 %. Linkage needs to be extended by 2 to 3 turns (set for symmetrical pitch with pitch gauge).
>> Kürzen des Pitchkompensatorarme:Washout arms: Use inner hole and shorten, so that they can't hit the phase pins (?) in case of vibrations (looks like they need to bend a bit to hit anything, but they recommend to cut off the end).
>>Zyklischer Ausschlag erhöhen:Even more cyclic range. Yippee. (I'm not sure if you should do all those mods at the same time. Probably those are different variants to achieve the same goal).
On the swashplate, use the 107-108 ballheads, 2 mm longer than default => same swash deflection, more pushrod travel, more pitch. clever!
Warning, the balls on the washout / radius arms remain unchanged.
You need to grind off a bit from the swashplate => green arrows.
there are some collision points between swashplate and linkage rods at full negative => grind some more.
>>Pitchausschläge einstellen +/-14°:Setting pitch: All other links remain at default length. The lower end of the swashplate at -14 degrees should be 10.5 mm above the chassis.
Servo arm length: 14.5 mm (picture).
linkage rod upper swash-to-mixing arm: 62.5 mm (picture)
the three lower links swashplate: 8.5 mm (picture).
I hope this makes some sense
