Marty,
I would get Glenn Curtis to help you a little. Anyway. You need to hold the Slow Stick into the air with the wind blowing and walk into the wind a watch the blades spin up and make sure that they are both spinning good.. On the ground you have to wait for them to spin up and lift off, you cannot pull it off or it will do what is been doing, going right or left because the blades have not reachedthe speed it needs..
Just don't get into a hurry to take off. A hand launch might be good also, into the wind when you hear the rotors whistling.
Jim
