No, mine is the 263. The 283 has not yet been approved in the UK for use on the 912 even though it is deemed by Kiev to be the most suitable match for the engine.
As for pitch, the Kiev pitch setting tools aren't that standard (look like they have been made by a 6 year old at nursery school !!!) so are more of a "relative comparison" than a definitive angle. I just have my static set at 5200. I seem to recall that shows 16 on the Kiev scale.
