Looking Good
I built the LT-40 approx 3 maybe 4 years ago. I still have the airplane and use it when I have a guest that wants to give RC a try.
I power it with a 10 year old FP-40 engine and although it's no fire breather it flys great. The hardest part is landing the airplane because it just keeps floating down the runway.
Good luck with your project, They are a keeper!
