Has any one heard about the release date? Does any on know the specs? Does it replace the G-23? Whats the cost?

In the December issue of Model Airplane News there is a column in called Thinking Big. The article starts on page 116, and ends on page 120 talks about the new G-26. Officially it is called the G260PU. The G-26 will be a direct replacement for the G-23. It features an improved cylinder design with four transfer ports, a narrow 1mm, high RPM single ring piston, and a new combustion chamber shape. It is rated at 2.35 hp at 12,000 RPM with the included canister muffler. That is supposedly a 24-percent increase over the G-23. No release date is given in the article. I would like to have it on a H9 Taylorcraft!
