Yes, I know, that he has the smaller one.This is the reason, why I recomended him the ESM retract for Ki 84, and this is the reason, why I bought the retract for the La-7 (it is bigger). Iwrote, that every CMP Zero needs a lot of weight in the nose, I thought every Zero of every size, not only Zero 50 CC. I wrote, that I have experience with Zero 50 CC, so I want to tell him, that I haven´t the same Zero as erec. Maybe I should wrote it better.
