David,

For the record, my C-ARF Rookie II is setup with elevators (inboard) and ailerons (outboard) with the canard throw set to about 32mm up/down. 42 flights with a P-120, no issues.

I realize you have a Kangaroo and I think you'll want to fuse the surfaces together and use a single link to the control surface to create elevons. I recommend that. Had I done that on mine I would have saved a little money and had an easier time programing my 9 channel radio.
