Nitro Models Kangaroo and Reflex on trailing edge
I am putting together an Kangaroo and doing some mods (have a thread going in the Tips and Techniques Forum)
I know some (all?) delta wings run some reflex on the trailing edge of the wing. (ie. ailerons or elevons up a few degrees) I noticed that the kangaroo has some reflex dialed in at the wingtips.
My question is this. Theres an airfoiled stab section with an elevator that goes right behind the prop. The stab is semi-symetrical. Should I install it upright like a normal semi-symetrical wing? Or should I invert it, to mimic the reflex on the bottom of the wing?

RE: Nitro Models Kangaroo and Reflex on trailing edge
Install it upright as shown in the pic I'd say. You'll need the reflex and I also think that part of the hinging deal is to expose the leading edge of the elevator into the bottom airflow and duct it up over the upper surface. The drooped leading edge will help to do that.
