Some excellent comments, keep them coming.

To pick up on some points:

Deadsticks - I hardly ever have them either. Other than for running out of fuel (D'oh) I have never had a deadstick on my OS 61 FX and OS 91 FX, and only once on my YS 120 FZ and Laser 70. A few more on others, but can't remember the last time.

Running in before finishing the kit - Most of my engines have been in more than one plane and I certainly appreciate the benefit of not having to run in when in its second plane. However I don't see the point of running the engine until the plane is ready to go. It always takes longer to finish a kit than I ever think it will, and I don't want to go through the hassle of running in the engine then laying it up for storage when I can leave it NIB.

Hobbsy, I'm glad your not one of the people I thought I might have upset!

Well at the moment the majority of you seem to have a test stand, and can't live without.
