In the past I have converted similar radios by swapping over the pot leads from throttle to elevator.
If you're lucky, that's all you'll have to do but if the centering and throws are out then you'll need to recalibrate the radio. In some cases (if there's no software calibration procedure) that can involve slightly rotating the pots so that the centering is correct but in most radios I've changed over this has been unnecessary.
Just make sure you take pictures beforehand so that if anything goes wrong you can return it to the original state.
If your radio has mechanical trims then you need do nothing extra, otherwise you'll also have to swap over the trim switch wires as well.
In some radios, the pots and trim switches plug into the logic board and it can be a simple case of swapping these plugs over. Murphy's law however, says that this won't be the case with your radios
