Standing behind plane, you want the engine to angle to the right 2 degrees(two thin washers under front two engine mounting holes).
Most ARF'S come with built in right thrust. No up angle. Your cg must not be correct if it noses over real easy. As you taxi, you must hold full up elevator to help keep tail down and better tail wheel steering.

I had a Great Planes Extra 300 that wasn't very good on taxiing, and it would nose over as is mentioned. I moved the landing gear forward about an inch and this solved the problem and made it very stable for taxiing. CG of the plane itself isn't the problem, it's the relationship of the CG to the wheels. I've found that for taildraggers the wheels need to be at least as far forward as the leading edge of the wing.
