Extruded or expanded polystyrene will be much easier to work with.

Now that you can cut your own wings you'll realize the possibilities that skill gives you.

A house dimmer to a 24VAC transformer at your local home center will work fine for a bow up to around 30" and will be much safer than 120V AC. You'll need one rated for HVAC, not just a doorbell.

One last thing to try if you have a mind to, try slaving another channel to the throttle and plug the esc's into two different channels.

If you are going with the delta wing, I'd keep the canard small and fixed. Use elevons on the wings just to keep things simple.
