2019 News and Events
Ole Ringstad, pictured above, recently displayed his BMW based 12 cylinder engine and related systems at Aero 2019 Exhibition in Friedrichshafen, Germany.  There is a YouTube interview of Ole available in which you can hear his update and see the engine as he displayed it.  Search AvWeb Video on YouTube and look for "Ole Ringstad's 12 CYL Sport Engine."  Ole plans to begin testing soon.  We are all pulling for Ole to successfully develope this powerplant.  He has put a lot of thought and effort into it and is close to running and proving.
Doll Ground Runs
John Baughman and Curtis Godfrey assisted with installing the prop (Well, actually, they did all the work on installing the prop!).  These fellows manned fire extinguishers and stood ready as we performed the first run with the prop on.  As noted in our earlier post, the run went well, discovering one oil line that I had failed to tighten properly.  Other than that, she did fine.  Another run a few days later went well, also. 
Above, we have laid out the left and right wing ribs on their respective rib blocks from Wing Station 150.00 (tip) inboard to 43.25 to measure for extending the blanks, and thus, the rib nose further forward.  This is a small detail that is not absolutely necessary for structural purposes, but it will allow for one more rivet forward, which will more closely match the original ribs.
We began a Condition Inspection on Doll in March, using the Inspection Checklist on this website.  Below, Brendon Doherty working the left main while I worked the right.  Should finish up mid April, when we will perform our final ground runs, put all the panels and covers and fairings back on, and get her ready to fly.

We'll keep you posted.
