Bart, Those two factory holes should be the 13˚ up-limit hole and the 9˚ up- limit hole. As I remember, the description of the 1320 STC said the same 9˚ up travel limit was called for by that STC as is used for the 415-D. It was initially presented to me as making all the significant changes to make the plane a 415-D except that the gross weight would only increase to 1320 pounds. What in the actual text of the STC specifies some other up travel limit that requires a control wheel shaft hole other than the 13˚ or 9˚ holes? What up travel is specified in the STC? Ed
