RE: Advice please for Rookie
Low wind makes the Slo-V and excellent choice, especially for your smaller field. I would recommend that!
For your larger field Again the Slo-V is good if the wind is low.
You could consider some others as well.
Multiplex Easy Star is an excellent plane and available RTF.
The T-Hawk is also an excellent plane which is available with or without radio.
Finally, if you prefer to be able to walk into the hobby store and buy the plane and the parts, then the Aerobird Challenger.
These three will be good for your larger field and, once you get good with them, you will probably be able to fly them at your smaller field too.
