IMO having two four stars 40 and 60 I would cut one wing bay to stop it from floating on landing.
Flaps what for? it flies very slow as is.
sheeting the wing again what for? the best feature about unsheeted wing is that you can fix in no time.
just to remind you guys its a Low wing from the ground.
you guys are looking how to get into mods that will delay you from actual flying, build it as instructed and go fly it.
