I think I will be getting the pipe from Wren. There have been good things said about these pipes.

The test run was short, but it read 7.2 lbs at 190,000 RPM. The load cell in this stand reads low so I will have more details once I run it myself on my test stand. I will record the temp, thrust etc.

I will likely use a throttle curve so I have half thrust at half stick. This is the advantage of running it on a test stand first. I will read the thrust and adjust the curve accordingly. Sorta like a reverse expo.

I too like the idea of LiPo's as I will try to keep the wieght of my L39 as low as possible.
