That's the basics of it, but trim and incidences can be very touchy. By leveling the stab, and checking wing against it, you are setting those together. But the stab should also be set with reference to the centerline of the model, as well, which is "built in" as the model is built, and rather diffiicult to change, once it is built. That's why a lot of Pattern Plane designs incorporate stab incidence adjusters during building. You can get quite involved, making minute adjustments on wing, stab, and motor thrust lines, to make the "perfect" flying airplane to your flying style. It just depends how much work you want to do...

Then, there's the engine thrust, which can be sometimes tricky to get just right - only crashed my Gentle Lady, with an OS .10 about 6 times, before I ended up with about 7 degrees of downthrust, so it wouldn't crash every time I landed!

There are several Trim Charts on the following websites, that can give you some pointers. They have basically step-by-step instructions, and they can give you a big insight into why your plane flies the way it does...and they cover everything from incidences, to engine thrust, to aileron differential, on and on. I use them all the time, especially with a new bird.

It's near the top, under "trimmming your plane"...check out all the charts, print out a couple, and go fly! Have someone with you, that can tell you the next step, and take notes of what you see your plane do...it's easy to forget on the ride from the field to home - don't ask how I know this!!

Good luck, let us know what you find out!!
