How do props relate when you drop the diameter.
on my TTPro .60 I'm running 12 x 6.
on the top flight prop chart, below the 12 x 6 comes the 11 x 10.
If I switched to an 11 x 10 I am now traveling 10'' per revolution ( theoreticly (sic)) But I dropped an inch in diameter so how does this 11 x 10 relate to to 12 x 6 ????
Is there an overlap in the performance of the low pitch 12'' and the high pitch 11'' ?

The 11x10 (in general) will have a faster top end straight and level speed, accelerate slower, and be less appropriate for hovering and pulling through long uplines.
You're trying to maintain a similar load on the engine to keep it in its power band. So if you increase the diameter you want to lower the pitch unless you're trying to change your top end RPM for some reason.
