Ailerons are already on the bottom. I used 2 bolts and a front lip system to mount the wing. Right now I'm just looking to have some fun, maybe later I'll do combat. Our club is not real big on combat. We do have one guy who wants to try it though. He is flying a delta style with an OS .40la. I think my ST .40 might leave him behind! I also added light weight wire landing gear so that should prevent things getting caught in the linkage. I'll post a picture later.
