Is anyone running the 3/67 currently? If so, in what?

They are good engines and run reliably. The length is 8.7", 4.3" dia. It would be nice if there was a way to get 10# of thrust out of it. I'm currently flying one in a Midwest He-162. It's been my testbed. Initially flown with a dynamax/OS65, it now flys with the turbine. Carrys 46oz of fuel. A mixture of K-1 and Coleman fuel(white gas).
