RE: sig 4* 40
Is the 46 an LA or AX? The AX would work well. I moved a 46LA from my trainer to the 4 *, but shortly after, I bought and installed an OS 50SX.
A suggestion I make when I see someone getting a 4 * is to add an extra set of hinges one bay inward from the wing tips. The wing on the 4* is large, and the plane floats forever on landings. Sometime down the road, you may want to do a popular modification and clip the wings one bay. This will improve the roll rate and the plane will still be gentle on the landings. If you have hinges already installed one bay inward, it'll make the modification a lot easier. And if you don't ever clip the wings, an extra set of hinges won't hurt.
