Popriv,

The easiest way is to use an incidence meter to set stab, wing, and thrust settings. An incidence meter is a good investment having been a great tool for me for years once I realized its true values. You can setup thrust lines using a level and a protractor albeit more difficult. Building them straight from the ground up certainly results in more enjoyable flying.

Your on the right track in getting your airplane setup correctly. Personally I try very hard to get everything setup mechanically correct first before ever going to the computer mixing. Centering the trims via linkage adjustment as much as possible to ensure the greatest mechanical advantage for the servos. Take your time use the trimming information above taking everything one step at a time. Test fly between changes being sure to take notes as to what you have changed and how much so a change can be easily be lessened or reversed. Your end result will be a good flying machine.

Regarding taking your time: One of the most difficult things for me to do was to learn to work on only 1 thing at a time. You will maintain greater consistancy in your efforts, and you will know when you are done with each step. I used to try and do 3 or 4 things at once, and it resulted in misinterpreting the results, and making many changes incorrectly. Just one step at a time, and it comes together much faster.

Tiger 60 - one of my favorite flyers. See my gallery.

Washers used to shim the mount are ok, but only temporarily. They compress the wood and the angle then changes.

Actually, the above website is a whole lot of great information
