RE: DLA 112 ???
I was referring to the DLA. I'm steering clear of YD-A comments until a bit later if I make any at all.
The DLA that was checked out had a prop hub run out in the double digits with a prop shaft adaptor that had almost double the hub amount of run out. There was more but that is enough to eliminate an engine from use. The prop induced vibration would be just terrible and there would be nothing the average modeler could do to correct it.
