With no experience at all in this area, I had imagined that the engine would be turned about a vertical line through the prop flange. This, to induce the required side thrust while keeping the spinner back plate centered over the hole in the cowling.
Lynn E. Hanover This will have very little to do with RVs, but John Dyke specifies 2/3rd of one degree right thrust on the Dyke Delta. That is hinged at the prop flange. He also specifies 1.5 degree upthrust, but that is hinged at the firewall.
Bobby, a better way to measure the offset is to break out the old geometry book and calculate the offset. The sin(1.25)x47" is 1.02". The end of the engine will move off center by a long inch. You won't be able to read 1/4 degree on most protractors, but an inch is easy to make out.
