Hmm, 34 years of flying RC
Dozens and dozens taught over the years.
LT-40 is absolutely the best 1st airplane.

Balance it forward where shown with throws indicated - fly’s well for initial training

Move balance toward the rear and increase throws - learn basic acrobatics

Inside/outside loops, rolls, and all combinations of these basic maneuvers.

Works well with 40’s and 45’s, use a lower pitch prop like 10-5 or 11-5
