What do you do when your engine has more power than you need and you have to run it rich in a full 4 stroke. I know several ways to get less power but which way is best.
The typical solution is to reduce the venturi diameter .005" at a time until you get the right setting at the right speed. That will also smooth out the run. An alternative, possibly better, solution is to reduce the pitch to reduce the efficiency in level flight. You can set it leaner to get the same airspeed, then the efficiency will increase dramatically in the corners. A third alternative is to reduce the nitro, which will also let you run leaner but increase the in-flight variation, too
Which of these is best is a matter of experimenting and optimization. To first approximation, you should try each method, and then optimize around that (which may include engine, trim, handle settings, and flying adjustments), then try the next method, repeat, and at the end, decide which works best. With a lot of experience you can short-cut some of it, but overall this is a few weeks worth of flying sessions at least, and you need a wide variation on the weather to really find the best.
