Falps or flaperons
Yeah, I guess you're right. F-16 and F18 etc do use flaperons. If you are planning to have your CG on your trailing edge and have a computer fly your plane, then I would also use flaperons. Otherwise I suggess you use Tailerons for steering and flaps as flaps. I fly my F-16 with tailerons and it works just fine right down to touchdown.
