If you are going to try and take off using lots of canard make sure you have a way of changing the throw in-flight. During your takeoff roll leave your controls neutral until speed builds to let the wings and canards start to have laminar flow. If you hold full control like a soft field take off it will take longer to get the surfaces flying, and then bang they will become effective all at once and you will jump into the air.

Thanks for useful info. I will have the canard set up with dual rates - the large throw only for take off (as I said earlier). The very useful piece of information is to wait with the elevator/canard input until the speed has picked up.
Intention is to have the gear set up like the original with the main wing neutral and the canard slightly negative. During take off I will then need to pull the stick back slightly to level the canard.
