11X6 2 blade or 10X7 3 blade should be fine on a strong 46.
Take pictures at the field before you fly it.
I'm assuming you've mastered your trainer.
Check all control surfaces, make sure NOTHING is reversed.
Range check the radioboth with the engine off and running (have someone stand "on the tail" to do your range check with the engine running).
Give all control surfaces a tug to make sure the hinges are still stuck good.
Make sure all servo screws are tight, and make sure you have a "safety" (either clips or fuel tubing) installed at every control horn.
I recommend you stand on the runway, behind the plane for the first takeoff. Tail draggers act differently than trainers, and it will pull left quite a bit until the tail comes up.
Don't yank it off the ground, let it fly itself up.
Keep the gear down. Never raise the landing gear on a maiden. Just trim, fly, and landall within 6 or 7 minutes.
When landing, fly the plane all the way down.
Oh, and most importantly, check the CG one more time before leaving the house. Make sure it's balanced, and the batteries are still good.
Good luck.
