I started flying two years ago, so I am still a newby. My first radio was a Hitec laser 6. It came with my first trainer which is tail dragger kit. While building the kit, I was so anxious to get in the air, I picked up an ARF trainer which has tricycle landing gear. The laser 6 worked out okay with one plane, but when I finished the kit while getting ready for flight I found myself always having to trim out each plane every time after take off. Not necessarily a bad thing, more of a nuisance of needless field adjustments, and possible risks of wrecking the planes.
I have recently purchased a Futaba 9 CAP Super which will store all of the planes I foresee every having, and a foam Edge 540 wanting to get more flight time in with the foamie due to convienence. Getting the Futaba 9 was the best decision I made in my two years with the hobby. My suggestion would be to spend a little extra on a quality radio like Futaba or JR rather than buying twice.
