RE: Not a second plane but an additional plane
Blazer, there are a number of planes out there. A couple that you might want to consider:
1. Avistar- It`s a trainer, yes, but with a good 46 up front it can take you to the next level. It can be more of a sport plane than your LT-40 but still retain some trainer like characterics.
2. World Model T-34. Easy flying low wing trike gear. Super smooth flyer.
