If a person utilizes a good instructor, a low wing trainer like the 'Hangar 9 P51 PTS' might work for a lot of new pilots.
In the US, many AMA chartered clubs have volunteer instructors so the instruction is free.
You might check the BMFA site (http://www.bmfa.org/) to see if it's the same in the UK.

No matter how "good" you are on any simulator, flying a real model is different.
