RE: Flaps or flaperons?
I agree with everyone here. I use flapperons on my seaplane so I can get it out of the water faster, I don't use them for landing. My throw measurement on the flapperon down is 1/4." On a semi scale plane like your mentioning is not a good idea. Some fast sport planes, flapperons are fine, and others forget about it! Your plane was designed to fly scale like, any extra quick drag your plane could make your plane eat dirt before you know it.
