As for the second point, I specifically asked Paul at RC customer service about the F3 recommendation and he said RC would never recommend that setting. I said I heard it was in writing and he said, not from RC - it may have come from a reseller, but not RC. Since I have never seen how this was written, I couldn't specifically speak to it. Do you have a copy of the recommendation? It would be interesting to send it to Paul for his opinion and get this cleared up.
Here is the page from the booklet that came with my RC. Since the factory settings were E0, the bottom grouping applies.
