In my experience (I am also a beginner), the .40LA is just fine. The LT-40 is a big trainer, so if you want fancy aerobatics, I would recommend the .46FX. My LT-40 flies just fine with the .40, and I can still fly it through some basic aerobatics. I waited on the .46FX until I had a plane that would suit it better. I would say if you're just learning the basics, go with the 40LA. Hope this helps, good luck
