The sig LT 40 trainer will work well for you. I am not familiar with the hobbico you mention, but if it is a high wing trainer with dihedral, it should be fine. It is possible to learn all by yourself, but if you have a computer, you can buy a simulator which will help a lot.

Another good airplane choice is the Kadet senior ARF. it flies even more slowly than the typical .40 sized trainers.
