RE: LT-40 main gear question
Assuming that you are new to the hobby, the flimsy main gear will flatten on your less than perfect landings. When you notice the tail is a dragging, just rebend until the plane is level. BTW, you have picked the very best trainer yet created. Balance toward the more nose heavy balances, and it trims out to recover from slight errors in control better. As you improve, move the battery back to balance towards the rear of the range, increase the control throws, and the acrobactics improve. It will fly inverted quite nicely, even do outside loops at that balance. All around a fun airplane to learn with.
Have your instructor teach you how to do loops and rolls, cuban 8's, split S's, etc, before he trys to teach you to land. Basic acrobatics build the eye hand coordination required to avoid rolling into turns when you are low to the ground. Practice slow speed flight while high above the ground. Practice flairing and landing approaches while 30 feet above the runway. When you can do that, then land.
