Hi Andrew - the 4*60 just happened to be my first kit build after starting to learn on a ARF LT-40.
Easy build and laser cut.
I like the larger size compared to the 40.
Easy to kit bash if you'd like. LOTS of building threads on the 4*60
If you click on my profile and follow the link to my RC site, I have a pretty good building thread with text on the 4* I did.
Good Luck and Good Flying
