Flaperons will make the airplane more likely to tip stall if it has ailerons only on the outer portion of the wing. Since the Ready has full span ailerons, they work fine. I had them on my Ready and Cessna and they did make the landing approaches steeper and slower. Using flaps correctly requires a different technique from normal landings and once it is mastered it is really fun. Putting flaperons on the Ready is not necessary at all, but it allows you to safely learn a new skill, which is always good.

Set the flap rate at 125% on your transmitter. You will need all the travel you can get in flap mode to made much difference.
