This past weekend I was able to take my Tower Trainer MKII out for my first ever flight and My son and I had a blast. I bought the plane used and want to make sure that I am giving the plane proper maintenance in between flights. What are some things I should be doing to the plane to make sure that I have successful flights each time with no stalls or equipment malfunctions? What is the proper maintenance for the servos and engine, elevators and ailerons ect..????
