Please find attached photo of my completed 10.6 cc v8 aero engine. About 600 parts in total. Still have not got it to run yet due to lack of compression. I suspect the valve springs to be too light. Will change these some time. If that dues not work I will remake the pistons with more metal on top to raise the compression. Enjoyable to make but too small for me! Started now making a 1/4 scale Rotary BR2 to the Blackmore design. Which is a better size.
