My first kit was a Goldberg Eagle 63, which was the precursor to the Eagle II. Great plane both to learn to build with and to learn to fly on. Just take your time to understand the instructions and make sure you build it straight (make sure you use a FLAT building surface) and it should come out fine.

You also mentioned you were looking for a Tiger Shark or a Thunder Tiger engine, along with a used 6 channel radio. The only advise I would give here is to go with the Thunder Tiger engine if you are limiting yourself to these two choices. By most counts Thunder Tiger builds a fine product, especially their Pro .46. I have never heard the same said for Tiger Shark engines, though. Other possible engine options would be OS, such as the .46 FX, or the Tower branded engines from Tower Hobbies.
