L2, when you do compass swings, are these orbits relative to a fixed point or just constant rate turns ? I understood from your earlier post that they were the latter and that you said that these required constant changes in power.
Have I misunderstood ?

If they are constant rate turns then please can you explain why they need power changes as I am still stuck on this point as I see it as the same as the model in the train as there is no reference to the fixed ground.

Thanks
