That depends.

If you have the self discipline to limit the throttle manually, you will not have a problem, though you may have to mount your receiver battery behind the wing's trailing edge to get the model to balance properly. Adding weight to the tail is not the preferred method. Moving the absolutely necessary equipment around to obtain the proper balance is preferred.

If you have an instructor/helper person and if you need their assistance - I do not know your abilities - you might not have to worry about overpowering the model with the .46. I do know that some of the Falcon 56 Mk.II models would zip right along with a K&B .40 of the era and that it could cause low time pilots a moment of anxiety here and there. However you may be a fine pilot. I have no way of knowing. I do know that the modern .32 to .37 engines are considerably stronger than the old K&B .40 and are as light to boot. The more modern .46 schneurle ported engines tend to be heavier. The weight is more of a worry than the extra power.

I'm sure that the venerable old Falcon 56 Mk.II can be built to accept either size engine without a problem. You might have to be a bit more creative with the .46, but it can be done.
