LT-40 is a great choice, and not a difficult build. Follow the instructions and it will turn out great. My only suggested mods would be:

replace the push rods in the kit with something a little less temperature sensitive;
add additional suport for the push rod tubes in the fuslage near to servos;
replace the plastic clevises; and
add some triangle stock between the vertical stablizer and fuselage.

Other than that, build it fly it have fun.

Good luck!
