Many times when I suggested that they give it a try, they would come up with many excuses, like they have no interest. Once I twisted their arms by double dog daring them by saying, "If you're afraid of not being able to fly my "toy" airplane, I understand". Once they felt they had no choice and got a few minutes on the sticks, all of a sudden, they became very interested. I found out when someone claims to have no interest, what they are really saying is they're afraid of giving it a try. Of course their ego won't allow them to come right out and admit that they're scared. lol
