It's been 4 months since my last update as I have been wrestling with UL Power over obvious quality control issues. Fortunately, I was able to get down to the bottom of the issues and find exactly why these piston/cylinder issues are happening. The details of this will be posted on my blog at www.myulpower.com
However, now the engine is back together and running well in preparation for the sale of N316NM. What!? yes that's right, times are changing and I have a new project on the horizon so 316NM has to go. www.316nm.com for more information. Until she sells, I'll be keeping the build log up to date.
