well --- our engines do differ--in that most of the gasoline specific purpose model engines are aluminum cast jugs with a coating only on the inner walls
On most big stuff they use steel barrels - whole different ballgame
aluminum looses 50% of strength at 500 F
On some small industrial engines they use liners and on some converted gassers - liners
these are much more rugged in withstanding cyl pressures at high temps .
Also engines such as the ROTO there are cylinder liners

very rugged, but heavier setup
checking after landing ain't all that bad -as long as the test is consistant
Look at it this way----
adjust mixture and prop load to produce a power curve that NEVER sags

Listen to the engine
Look at theplugs
also measure temp -however you choose to do it
If the sound stays right and the temp remains the same -you are doing the right thing
As for racing engines which keep moving - I would want an on board temp -and then I would push that engine to the limit - that is what racing is all about
I would blow up an engine at least once - find out what it could stand.

been there -but in cars not models except way back when on Quickies
