Maybe there is a translation barrier there so I’ll restate the above.
I am not arguing the R-77-1 doesn’t loft. I’m sure there are people here who know a lot more about that and I’ll defer to them. For the sake of the argument, lets assume the R-77-1 DOES loft.
From what I am seeing above there is zero evidence the R-77 BASE lofts. So my question is, Why, in the absence of evidence of the BASE R-77 lofting, would you assume it does loft?
Yes, but as you said it is logical.
You cannot just say this for the base R77. As you’ve proven, the R33 indeed does loft but the base R77 remains unproven to loft. R27 manual doesn’t state whether it lofts or not.
