Looks like you just need to check out their website to get all those answers, I don't know all those numbers off hand.

The handle is going to give it some lift for sure. It's got a slight postive angle of attack on it. So does the top of the black dummy engine compartment.
The rudder I'm putting it on the back in the middle. Just making it out of coroplast, sinking it down into the foam withe epoxy like in this pic. That is the basic shape I'm using, but prolly will make it as tall as it can go under the dummy engine housing. Cutting a slot in the coroplast for the hinge. Then using a pull pull wire. There is a servo for the main wheel already there for you ... might as well put it to more use and only costing me about $5 more for the pull pull rig. The wing is fun fly shaped and now with a big strong rudder it's going to hopefully hover and 3D well ... we'll see!
I was supposed to have this done a while back, hope to get it flying real soon!
