I need some help picking a cub. I have an os .25 engine for it. I am looking at either a Global J-3 Cub 25 ARF .20-.28 with a 48" wing span for $99.99, a Modeltech J-3 Cub with a 48" wing span for $89.99, or a Thunder Tiger Lazy Tiger Cub Slow Flyer for $99.99. I would like to get something that I can use flaperons on. Would I be able add a servo so that I can use flaperons if the ARF doesn't come set up for them??

Any other thoughts on these cubs?? Anyone with experience on them??
