Question: How many get past the first trainer?
When most seasoned fliers think of trainers, the little 40 size planes immediately come to mind and is what they often recommend for beginners. These little toys are fine if the beginner is twelve years old or younger. Most grown men entering the hobby however, would benefit more from starting with a larger and better flying flat bottom winged airplane. The absolute best of which is the Kadet Senior ARF. This is a big, well built, sharp looking plane that flies extremely well. It's also a very versatile plane that a person isn't likely to bore with quickly.
I think one reason beginners get itchy to move on to a symmetrical winged airplane is due to having made a poor choice with their first plane. Another reason may have to do with their age. The younger the beginner the more he is going to associate a faster and badder plane with a bigger... well, you get the idea.
