I am about to make my first glow plane purchase. A lot of people seem to think the LT-40 is one of the better planes for beginners. However, bigedmustafa pointed me to the Thunder Tiger 60 plane at the following link:

I kinda like the idea of a 60 size plane over a 40. I assume the 60 is a little heavier plane? I currently have the HobbyZone Super Cub electric plane. I have been trying to teach myself to fly and it has not gone well. I'm hoping by hooking up with an instructor and using a glow plane I will have better luck. The Super Cub just seems so light that I struggle with it.

What are the advantages/disadvantages in learning on a 60 size instead of a 40?
