Rick,
I am told that partial throttle takeoffs are actually less beneficial to the engines than full. The reason is that in the last part of the throttle travel, the mixture is enriched. So if you run full throttle, the engine is getting a richer mixture than partial. BUT...
If you are going to climb for 10 minutes at "the top of the green", and if you have enough runway, I myself don't see why it hurts. The engine does not know it is the first minute of takeoff vs the other 10. Unless you count the very brief period of reduced airflow during the takeoff roll.
In the end, I always do full throttle takeoffs because I don't believe it *reduces* engine wear to do partial throttle takeoffs, and I want to be at 1000' AGL as quickly as possible, to give me altitude to deal with an engine failure.
My 2 cents.
Kevin
