I searched around the net and could not find anything on prop indexing for my GPAS 2180.
Reading mark's website it said vertical prop with #1 TDC, but that's a corvair. Looking at doing that on my vw, it would make hand propping hard if the spark comes at that position (my slick mag has an impulse coupling). I ended up putting the prop hoirizontal at #1 TDC thinking that while hand propping I'd rather have it fire half way down the swing. Maybe 4 or 5 oclock blade at #1 TDC would be better. The plane has an electric starter, but should be able to be hand propped. The other issue is dead stick landings, the prop needs to be horizontal then. Does the vw tend to stop in any particular position while gliding? Any ideas? jg
