Yea, I can actually tune it to about 10,500 on the ground with a good wooden 18x6 and I can get around 10,000 on the APC but the engine tends to lean out and pull more RPM in the air so I always tune it back to a rich state on the ground hoping for about 9,500 in the air with a good smoke trail. The main point is I can pull about 1000 more RPM with the header and can AND save 6 real onces of weight.

And Tom, shame on you teasing us with a flight report on a possible new plane with an OS 160 then telling us it is way to much engine. We are real men, Tim Talor men, Drive her till she blows men, Men who have sold all of our little engines. Guess I will just leave it on the Tunnel Vision (which is way to much fun anyway) and live without a Baby Bunny for a while longer.
