Ditto with what squeakalong said. Go with something easy on the first build that flies well. My first kit was a P51 by dynaflite. I did get it finished and it flew it did not fly very well because of lack of experience building.

From the three choices you give I'd agree the TF Elder would be the starting point...however the Elder takes some skill to build correctly and you have the tail-dragger aspect to consider for take-off and landings. As a long time builder and flyer, and seeing from your post you have one ARF under your belt (hopefully still flying it) I'd suggest something like the Carl Goldberg Eagle 2 kit or Tiger 2 kit, or a SIG 4-Star 40 or Mid-Star 40. Any of these offer great manuals and plans and when built nicely are very successful in the air. The SIG Mid-Star 40 has a mid-wing design that offers a bit more stability and is a ball to fly; the 4-Star 40 and Tiger 2 kits are low wing models which are more agile in the air and, therefore, require more attention when flying from the pilot. All are good r/c models. PLEASE: if you are just getting started, stay away from the P-51 (and similiar type models) until you have 3 or 4 models under your belt. They are fast and require ALOT of pilot input/attention/experience to fly. We want you to be successful and enjoy the hobby so ask all the questions you want as you build and follow a practical model design learning curve. You'll be rewarded with a very good building/flying learning curve that will allow you to fly that P-51 later with confidense.
Soft landings.
