I'll give this a "go" here. First of all, if you're interested in flying any type of Warbird, I'd highly recommend visiting this site [link=http://www.rcwarbirds.com/Techniques/Technigues.htm]RC Warbirds - Techniques[/link]. There's a TON of information of flying warbirds and if you scroll down into the "Flight Operations" section of the page I think you'll get a detailed answer to your question.

As I watch some people at the field with WWII type aircraft it's full throttle and yank back on the stick, ya the airplane gets off the ground but not very realistic looking.
In my experience that's a recipe for Warbird disaster. You need to develop enough groundspeed to first bring up the tailwheel while managing rudder to keep the aircraft straight. This is a gradual progression of throttle, not a "jam it open" kind of event. If your takeoff doesn't look "scale" then you're probably not doing it correctly.

What actually produces this problem? Is it the touque from the engine, I thought this but I've tried to ease in with the throttle and the "loop" occurs. Do I ease the throttle, add down elevator and a little right rudder, I can't believe it's this difficult,...
I'm guessing here, but it sounds to me like you're taking off before the plane is ready or you're giving it too much elevator too soon, or possibly both. Yes, there's a torque factor that causes the plane to Yaw, but the severity is somewhat airframe dependant. What type of Airplane are you flying? It would help to know plane, engine and prop. Don't give up; you're correct its not that difficult, once you get the hang of it. Heck, I'll bet there was a time when you thought riding a bike was difficult, right?
