Well I thought I had my problem solved but it's back to square one for me too. I set my AD to 40 and ran my engine twice with no problems. Yesterday the local Hobbytown had a grand opening and I was asked to demonstrate my turbine. I tried to run it for the crowd. It started okay but when I tried to run it up it would sputter and flame out at around 120,000. The only difference I can tell was it was a much hotter day than the day I had the successful runs.

Where do I go from here?
