Thank you very much for the suggestion.
I have some washers that are ~.030" thick and some thicker ~.060".
How much down-thrust is typically necessary?

Thanks again,
Ryan

I'm not sure on the SAE sizes but I can tell you that a 1mm thick washer is good for approx. 1 degree. Based on you desription I would add 3 1mm washers to each top mount bolt to get 3 degrees of down thrust. You could start with 2 washers, fly it and then add more if needed

Make sure that your elevator is centered using the clevises and no trim in the transmitter.

What engine and prop are we talking about here?
