I taught my 6 year old how to fly by doing this exercise which leads to a lot of understanding of flight.
First establish pitch and direction for either up or down- like pull back or down on transmitter stick
Then do the same for aileron roll giving direction like left or right.
Quiz:
Child stands, ask I want to go------up and child reponds verbally and shows with right hand motion of pull stick back(slow of course)
Then try left roll,right roll and down. Do over an over.
Learning to fly is reactive where flying is proactive. You need to teach how to correct his/her mistake.
Game now, what do I do?
Have the child walk and you behind them will introduce a problem and the child will react by telling you and moving his hand to correct for his mistake.
Example:
The child is walking(and you) and you push their left shoulder down(your going left and I want you to go straight talking), so the child responds by moving his left shoulder up and the hand goes to the right. You say stop when he is level and you take the unequal pressure off the shoulder.
So the left or right shoulder are the ailerons and pushing forward or pulling backward on both shoulders is the elevator!!!!
Game 1 -- trying to keep the plane level only. After mastery--
Game 2 -- now explain right and left turn where the aileron needs some up elevator.
Game 3-- now you explain what a cross wind does and how you correct in each of the 4 conners.
Game 4-- fly in a circle and maitain the same height.
Kids at that age should go for it using a buddy box and time in the air. If they adapt, then you will move thru each game.
If it doesn't come together, try 6 months or a year later.
At our club, a totally deaf person wanted to learn how to fly. So I came up with this approach and he soloed in a short time.
Ailerons pressure were the shoulders, elevator was pushing forward or pull aft on shoulder, rudder was turning of the head and throttle was thumb on the back of the head either up or down.
